Let's start with the thing nobody tells you: "fungal acne" isn't actually acne. Not even a little bit.

It’s a completely different skin condition called Malassezia folliculitis, and it’s caused by an overgrowth of yeast, not bacteria. The reason this matters so much is that the treatments for regular acne (antibiotics, benzoyl peroxide) don’t work on it. In fact, antibiotics can make it significantly worse. And here’s the kicker: a study of 320 patients who walked into a dermatology clinic thinking they had acne found that nearly 29% of them actually had Malassezia folliculitis. That’s almost one in three people being treated for the wrong thing.

So if you’ve ever had stubborn, itchy bumps that won’t go away no matter what acne product you throw at them, keep reading.

This article is going to walk you through what’s actually happening on your skin, how to tell if it’s fungal, how to treat it, how to keep it from coming back, and why the internet’s “fungal acne safe” ingredient lists are well-intentioned, but scientifically oversimplified.

So what exactly is going on with your skin?

Here's where things get interesting. The yeast behind fungal acne, Malassezia, isn't some foreign invader you picked up somewhere. It already lives on your skin. On everyone's skin, actually. It makes up over 90% of the fungal community on human skin, and somewhere between 75–98% of healthy adults carry it. You've had it since you were born; it was likely passed to you from your mother's skin.

There are about 18 known species of Malassezia, but the ones most commonly involved in skin problems are M. globosa, M. restricta, M. sympodialis, and M. furfur (Gaitanis et al., 2012, Clinical Microbiology Reviews).

Now, here’s what makes this yeast truly unique in the fungal world: it can’t make its own fatty acids. Every other free-living fungus can synthesise long-chain fatty acids on its own, but Malassezia has lost the gene responsible for that. So it has to steal them from you, specifically, from the oily sebum your skin produces.

To do that, it has evolved an impressive arsenal of lipase enzymes, way more than other fungi. These lipases break down the triglycerides in your sebum into free fatty acids that the yeast can absorb and use. M. globosa in particular has a lipase called LIP1 that's about 100 times more active than the lipase from the acne bacterium C. acnes. It's basically a professional-grade sebum-digesting machine.

When commensal becomes chaos

Under normal conditions, this all works fine. The yeast eats a bit of your sebum, your immune system keeps it in check, and everyone coexists. The problem starts when something tips the balance: too much sebum, a weakened barrier, antibiotics wiping out competing bacteria, or a suppressed immune system, and the yeast population explodes inside your hair follicles.

When that happens, Malassezia overwhelms the follicle, the follicular wall ruptures, and your immune system mounts an inflammatory response.

How to tell if it's fungal acne or regular acne

This is the million-dollar question, and unfortunately, even dermatologists get it wrong a lot. A systematic review of over 1,200 patients found that 40.5% had a history of unsuccessful prior treatment, mostly antibiotics prescribed for what doctors assumed was regular acne. In a review of 110 pediatric cases, over 75% had been treated with antibiotics for supposed acne before anyone figured out it was Malassezia folliculitis.

But when you know what to look for, the differences are actually pretty clear.

Regular acne (acne vulgaris) looks like this:

Mixed lesion types: blackheads, whiteheads, inflamed pimples, cysts, all different sizes.
Concentrated on the face, especially the T-zone, chin, and jawline.
Individual pimples can be large and deep.
Usually not itchy.
Responds to antibiotics, retinoids, and benzoyl peroxide.

Fungal acne (Malassezia folliculitis) looks like this:

Uniform, small (1–2 mm) bumps: they all look the same. This is the biggest visual clue.
Often on the forehead, chest, upper back, and shoulders, basically wherever you have a lot of oil glands and hair follicles.
Itchy. This is a major distinguishing feature. Patients with MF were 7.4 times more likely to report itching than those with regular acne.
No blackheads or whiteheads (no comedones).
Does not respond to antibiotics, and may actually get worse on them.
Responds quickly and dramatically to antifungal treatment.

If your "acne" is itchy, looks like a rash of tiny identical bumps, sits on your trunk or forehead/hairline, and hasn't budged after months of typical acne treatments, there's a very good chance it's fungal.

Your skin microbiome: why balance is everything

Your skin is an ecosystem, and Malassezia is one player in a larger community. On oily skin sites (face, chest, back), the three dominant organisms are the acne bacterium Cutibacterium acnes, Staphylococcus epidermidis, and Malassezia species. Even though bacteria outnumber fungal cells by a huge margin, Malassezia cells are physically much larger, so their functional presence is roughly equal to bacteria.

Crucially, these organisms compete with each other. Research shows that C. acnes has hostile interactions with both Staphylococcus and M. globosa; they're essentially fighting over the same territory. When you take antibiotics, you wipe out C. acnes, removing the competitive pressure that was keeping Malassezia in check. The yeast then proliferates unchallenged. This is why antibiotic use is one of the strongest risk factors for developing fungal acne.

Your skin barrier is the gatekeeper

A healthy, intact skin barrier is surprisingly important in preventing Malassezia overgrowth. A key 2024 study demonstrated that it wasn't a weakened immune system that allowed Malassezia to thrive; it was physical barrier impairment, including increased water loss through the skin and structural disruption of the epidermis. When the barrier is damaged, the yeast gains enhanced fitness for colonisation.

Ceramides, the waxy lipids that hold your skin cells together, play a direct role: Malassezia growth is inhibited when ceramide levels are adequate.

And here’s the vicious cycle: Malassezia‘s lipases generate oleic acid from your sebum, which directly disrupts your barrier, which increases water loss and inflammation, which damages the barrier further, which lets more yeast in. This lipid dysregulation–barrier disruption–inflammation loop is self-sustaining and explains why fungal acne can be so persistent once it takes hold.

The takeaway? Stripping your skin of all oils to “starve” the yeast, as some online advice suggests, can actually backfire by destroying your barrier and making the environment more hospitable for Malassezia, not less.

What causes flare-ups (and why antibiotics are the worst offender)

Fungal acne doesn’t just appear randomly. There are clear, documented triggers.

Heat, humidity, and sweating are the biggest environmental factors.

MF is dramatically more common in tropical climates and during summer months. COVID-19 ICU patients frequently developed it due to the combination of fever, sweating, occlusive positioning, and broad-spectrum antibiotic use.

Antibiotics, especially tetracyclines (doxycycline, minocycline), are perhaps the most underappreciated trigger. In Prindaville's series, over 75% of MF patients had been recently treated with antibiotics. The mechanism is ecological: antibiotics kill competing bacteria, removing the natural check on yeast overgrowth.

Immunosuppression increases risk significantly. MF is common in HIV/AIDS patients, organ transplant recipients, and people taking systemic corticosteroids. One study found M. furfur in 16.7% of HIV-positive patients versus just 1.3% of HIV-negative controls. Heart transplant recipients developed MF within months of transplantation on immunosuppressive regimens.

Occlusive clothing and heavy skincare products create the warm, moist, lipid-rich environment the yeast thrives in. The 2023 EADV position statement specifically advises avoiding heavy emollients, occlusive topicals, and non-breathable fabrics like nylon.

High-glycemic diets play an indirect but mechanistically sound role. Foods that spike your blood sugar drive insulin and IGF-1, which stimulate your oil glands to produce more sebum through the mTORC1 pathway. A systematic review of 34 studies confirmed high glycemic load increases sebum production and acne severity. More sebum means more food for Malassezia, the connection is straightforward even though no randomised trial has directly studied diet and MF specifically.

Hormonal changes contribute mainly through sebum; peak Malassezia colonisation coincides with puberty when sebaceous glands become active.

How to treat fungal acne: what the clinical evidence actually supports

Let’s cut through the noise and look at what’s been tested in real studies.

First-line: topical antifungals.

For mild to moderate cases, topical treatment works well and is where most people should start.

Ketoconazole 2% is the most studied option, achieving clinical cure rates of 73–88% in trials. A Japanese study found that topical ketoconazole cream resolved cases in an average of 27 days.

The shampoo version (Nizoral or generic 2% ketoconazole shampoo) can be applied as a wash, lather it on affected areas, leave it for 5–10 minutes, then rinse.

Zinc pyrithione 1–2% (found in Head & Shoulders and similar anti-dandruff products) works by disrupting fungal cell membranes and depleting their energy stores. The EADV gives it a Grade A recommendation for MF treatment.

Selenium sulfide 2.5% (Selsun Blue) is one of the oldest treatments studied. Applied daily for several days then weekly for maintenance, it showed good results in clinical trials.

Ciclopirox olamine (0.77% gel or 1.5% cream) works through a different mechanism; chelating metal ions essential for fungal metabolism. The EADV also gives it a Grade A recommendation, applied twice daily for 2–4 weeks.

For more severe cases: oral antifungals

When topical treatments aren’t enough, oral antifungals are highly effective. A systematic review found oral antifungals achieved a 92% success rate compared to 81.6% for topical therapy.

The only true randomised controlled trial ever done for MF tested itraconazole 200 mg daily for 7 days against placebo. At five weeks, 84.6% of the itraconazole group was healed or markedly improved versus just 8.3% on placebo. Oral itraconazole also worked faster than topical ketoconazole, 14 days versus 27 days to resolution.

The EADV recommends itraconazole 100–200 mg/day for 1–4 weeks, or fluconazole 100–200 mg/day for 2–3 weeks. In a comparative trial, combining oral ketoconazole with ketoconazole shampoo achieved 100% clearance, better than oral alone at 75%. Oral antifungals do require a prescription and liver function monitoring, so you’ll need to work with your doctor.

One important note: not all topical antifungals work equally well. In the same comparative trial, topical econazole solution and miconazole cream performed poorly as standalone treatments, likely because the vehicle and the drug’s ability to penetrate into the sebaceous follicle matter as much as the active ingredient itself.

Keeping fungal acne gone: the maintenance plan that actually works

This is possibly the most important section of this entire article, because here's the hard truth: Malassezia is a permanent resident of your skin. You cannot eradicate it, and you shouldn't try to. The goal is keeping it in balance, and without ongoing maintenance, recurrence is the norm.

The data is clear on this. After successful treatment with ketoconazole shampoo, 47% of patients relapsed within six months without maintenance therapy. With regular maintenance, that rate dropped to 19–31%. Multiple clinical reviews note that relapse occurs in the majority of cases when treatment is simply stopped (Rubenstein & Malerich, 2014; Henning et al., 2023).

Think of it less like “curing an infection” and more like “managing an ecosystem.” You’re maintaining the conditions that keep a naturally occurring organism from overpopulating.

1. Regular antifungal washes: This is the cornerstone

Pick one and use it consistently on previously affected areas:

Ketoconazole 2% shampoo used as a body/face wash 1–2 times per week. Apply to affected areas, leave on for 5 minutes, rinse. This is the most evidence-supported maintenance approach.

Zinc pyrithione 1–2% wash 2–3 times per week, also helps with any associated dandruff or seborrheic dermatitis.

Selenium sulfide 2.5% once weekly.

The key is consistency. These aren’t “use until it clears up and stop” treatments; they’re ongoing maintenance, similar to how someone with dandruff uses anti-dandruff shampoo regularly rather than just during flares.

2. Barrier repair: protect the skin you’ve worked to clear

This might sound counterintuitive given the “avoid all oils” advice floating around online, but barrier damage is itself a driver of Malassezia overgrowth.

A stripped, dehydrated barrier creates the conditions for the yeast to thrive. Your maintenance routine needs to keep your barrier intact using ingredients that hydrate without feeding the yeast.

Focus on humectants like hyaluronic acid, glycerin, urea, and panthenol; none of these is lipids, and Malassezia cannot metabolise them.

Niacinamide (vitamin B3) is arguably the single best active ingredient for MF-prone skin maintenance: it regulates sebum production, strengthens the barrier by boosting ceramide synthesis, and has mild anti-inflammatory effects.

For safe emollients, use squalane (a saturated hydrocarbon with no fatty acid character), caprylic/capric triglyceride (confirmed non-growth-promoting by Dobler et al., 2019), or lightweight gel moisturisers.

Ceramide-containing moisturisers are clinically important for barrier repair; despite what some internet lists claim, their benefit in restoring barrier function likely outweighs theoretical risk.

3. Manage sebum production

Less oil on your skin means less food for Malassezia.

Use niacinamide (4–5%) daily: it reliably reduces sebum production.
Azelaic acid (15–20%) has antifungal, antibacterial, and anti-inflammatory properties all in one, plus it helps fade the post-inflammatory dark marks MF often leaves behind.
If you’re on hormonal birth control, discuss options with your doctor; some formulations reduce sebum production.
Consider your diet ( more on this below )

4. Lifestyle and hygiene habits

These sound simple, but they make a real difference.

Shower within 30 minutes of sweating: heat and moisture are among the strongest documented triggers. Don’t sit in sweaty gym clothes.
Use an antifungal wash after exercise. Even a quick post-workout application of a ketoconazole or zinc pyrithione wash to your chest, back, and shoulders can help prevent flares.
Change out of damp or sweaty clothing immediately. Occlusion + warmth + sebum = Malassezia paradise.
Wear breathable, moisture-wicking fabrics. The EADV guidelines explicitly recommend avoiding nylon and non-breathable materials over MF-prone areas.
Wash sheets and pillowcases frequently: at least weekly in hot water.
Be careful with hats, headbands, and helmets. Anything that creates occlusion and traps heat against your forehead and hairline.

5. Stop unnecessary antibiotics

If you’ve been prescribed oral antibiotics (especially tetracyclines like doxycycline or minocycline) for acne, talk to your dermatologist about whether they’re truly needed. These are the most consistently documented trigger for MF because they wipe out competing bacteria and give the yeast free rein.

6. Watch for early warning signs

You’ll learn to recognise the start of a flare, often a few itchy bumps in your usual trouble zones, especially after triggers like a hot, humid weekend, wearing a heavy backpack, or increased stress.

Catching it early and ramping up your antifungal wash frequency for a week or two is far easier than treating a full-blown flare.

7. Consider periodic “pulse” treatment

Some dermatologists recommend periodic oral antifungal “pulses”. For example, itraconazole 200 mg on the first day of each month as prophylaxis, particularly for patients with recurrent severe episodes.

This is a conversation to have with your doctor, but it’s an established strategy in the clinical literature.

The “fungal acne safe” skincare trend: helpful spirit, flawed science

The online “fungal acne safe” movement, largely originating from the blog Simple Skincare Science and tools like Sezia.co and SkinSort, has done something genuinely valuable: it brought attention to a condition that dermatology has historically neglected. Thousands of people have finally gotten the right diagnosis because of these resources. That deserves real credit.

But the central rule the movement promotes: avoid ALL fatty acids C11–C24, ALL esters, ALL polysorbates, ALL plant oils, and ALL fermented ingredients, takes a kernel of real science and stretches it way past what the evidence actually supports.

What the science does say

The core fact is correct: Malassezia needs exogenous fatty acids with chain lengths roughly between C12 and C24 to grow.

The most comprehensive growth study found efficient growth on palmitic acid (C16) and oleic acid (C18:1), while myristic acid (C14) supported only poor growth in the species tested, M. furfur and M. pachydermatis (Liebregts et al., 2025, FEMS Yeast Research).

It’s worth noting that the predominant species in MF, M. globosa, and M. restricta, were not studied in this particular paper.

Medium-chain fatty acids (C8 and C10) aren’t just non-nutritive; they’re actively antifungal, destroying Malassezia cell membranes.

And medium-chain triglycerides strongly suppress Malassezia growth in a dose-dependent way.

So yes, the basic framework, Malassezia eats certain lipids, is sound.

But the internet’s application of that framework goes wrong in three big ways.

Problem #1: Concentration matters, and online lists ignore it

Malassezia lipid metabolism is profoundly concentration-dependent. At very low concentrations, certain lipids promote growth. At higher concentrations, the same lipids become inhibitory.

Polysorbates are a classic example: they support Malassezia growth at the low concentrations used in lab culture media, but become growth-inhibitory at higher concentrations. A binary “avoid” list simply can’t capture this nuance.

Problem #2: What’s in a Petri dish ≠ what’s on your skin

A free fatty acid floating in nutrient broth behaves completely differently from the same fatty acid locked in an emulsifier complex or encapsulated in a delivery system on your skin.

Malassezia‘s lipases show very different hydrolysis rates depending on the structure of the ester: ethyl esters are easily broken down, isopropyl esters less so, and complex glyceryl or decyl esters much less so.

So isopropyl palmitate (simple ester, easily hydrolysed) is genuinely risky, but glyceryl stearate functioning as an emulsifier in a cream is a fundamentally different beast.

The only peer-reviewed study that directly tested common cosmetic ingredients against Malassezia found no growth on caprylic/capric triglyceride, cetearyl isononanoate, polyglyceryl-3 caprate, fatty alcohol ethers, paraffin-based substances, silicone-based substances, or PEGs.

Many of these are flagged as “unsafe” by online ingredient checkers.

Problem #3: Your individual skin determines what’s a problem

The three-factor model for Malassezia-related skin disease established that oleic acid only caused problems in susceptible individuals; the same amount on non-susceptible people did nothing.

Your barrier integrity, immune response, microbiome composition, and genetics all determine whether a given ingredient will cause issues for you.

This is why your friend can slather on coconut oil with no consequences, while it makes your forehead erupt.

Which ingredients actually matter (and which ones you can relax about)

Based on the lipid metabolism research and the Dobler et al. cosmetic ingredient study, here’s a more evidence-based breakdown.

Ingredients with genuine evidence of feeding Malassezia

Free oleic acid (C18:1) directly demonstrated to disrupt the skin barrier and trigger inflammation in susceptible people.
Most plant oils rich in long-chain fatty acids: olive oil (55–83% oleic acid), sunflower oil, argan oil. These are essentially buffets for the yeast.
Simple esters of long-chain fatty acids: isopropyl myristate, isopropyl palmitate (easily hydrolysed by Malassezia lipases).
Polysorbates at typical low formulation concentrations: these are literally used in lab media to grow Malassezia.

Ingredients the internet wrongly demonises

Squalane: this is a fully saturated hydrocarbon, not a fatty acid or ester. It has no ester bonds for Malassezia lipases to break. Dobler et al. found zero growth on saturated hydrocarbons. It’s safe. (Just don’t confuse it with squalene, the unsaturated version found in sebum, which M. restricta can oxidise to generate inflammatory peroxides. That oxidation of squalene is relevant to dandruff and seborrheic dermatitis pathology. )
MCT oil (C8/C10 only): Not just safe but actively antifungal. Caprylic acid (C8) destroys Malassezia cell membranes. The critical caveat: the MCT oil must contain only C8 and C10 fatty acids, no lauric acid (C12), because Malassezia can utilise C12 chains.
Mineral oil: A hydrocarbon mixture with no fatty acid components. Confirmed safe by Dobler et al., though its heavy occlusive nature warrants caution in hot, humid environments.
Ceramides: These are essential for barrier repair, and impaired ceramide levels are themselves a risk factor for Malassezia overgrowth. The clinical benefit of restoring barrier function almost certainly outweighs the theoretical risk.
Caprylic/capric triglyceride: Specifically confirmed as non-growth-promoting by Dobler et al. One of the safest emollients for Malassezia-prone skin.

Ingredients that deserve genuine caution

Cetearyl alcohol: Often assumed safe because it’s a fatty alcohol rather than a fatty acid. However, Dobler et al. found it specifically promoted Malassezia growth in their testing. Worth being cautious with.
Fermented filtrates (galactomyces, saccharomyces). Fermentation can concentrate fatty acids and amino acids that support yeast growth. Direct peer-reviewed evidence is limited, but the theoretical concern is reasonable.

The coconut oil myth

One claim you’ll see everywhere is that lauric acid (C12, the main component of coconut oil) is antifungal against Malassezia. While lauric acid does work against Candida, Pohl et al. found it had no measurable effect on M. furfur membrane integrity. Meanwhile, Malassezia possesses enzymes that can activate and utilise C12 chains.

So coconut oil, despite its “antimicrobial” reputation, may actually feed the yeast responsible for your fungal acne.

Building a skincare routine that actually works

The goal isn’t to strip your skin bare; it’s to make smart choices that support your barrier while not feeding the yeast. If you would like me to write an article with my top recommendations for each category, please leave a comment in the comment section.

Cleanser: Use a gentle, pH-balanced gel cleanser (pH 4.0–5.0).

Malassezia lipases, particularly MrLip5, the main sebum-digesting lipase of M. restricta, show peak activity at alkaline pH (7.0–8.0), while acidic pH significantly reduces their activity.

Keeping your skin slightly acidic, therefore, makes your sebum harder for the yeast to digest, not just less hospitable to the organism itself.

If you like oil cleansing, use pure MCT oil (C8/C10 only) or a squalane-based cleanser.

Active treatment (during flares): Layer in one or more of these

ketoconazole 2% shampoo as a short-contact wash (5–10 min, then rinse),
zinc pyrithione 1–2% wash,
sulfur (3–10%), which generates compounds directly toxic to fungi,
or salicylic acid (BHA), which penetrates into the follicle to clear the sebum and debris that harbour the yeast.

Hydration: Stick to humectants Malassezia cannot metabolise

hyaluronic acid (polysaccharide, not a lipid)
glycerin (simple polyol)
niacinamide (regulates oil, strengthens barrier, anti-inflammatory)
urea (keratolytic + humectant)
panthenol (provitamin B5).

Moisturiser: Squalane-based lightweight moisturisers, caprylic/capric triglyceride-based products, ceramide-containing moisturisers (La Roche-Posay Toleriane), or oil-free gel moisturisers that rely on humectant technology.

Sunscreen: Mineral sunscreens (zinc oxide and/or titanium dioxide) are the simplest choice. Zinc oxide has inherent antifungal activity as a bonus.

Chemical sunscreen filters are generally outside the problematic fatty acid range, but mineral formulations avoid any ambiguity.

Targeted treatment: Azelaic acid (15–20%) deserves special mention. It’s antifungal, antibacterial, and anti-inflammatory, and it fades post-inflammatory hyperpigmentation, making it uniquely suited for MF-prone skin that tends to scar with dark marks.

Diet, supplements, and lifestyle: what the research supports

No randomised trial has directly studied diet and Malassezia folliculitis. But the indirect evidence is strong enough to be actionable.

Eat fewer high-glycemic foods. A low-glycemic diet reduces the insulin and IGF-1 signaling that drives your oil glands into overdrive. An RCT in adolescent males showed a low-GI diet decreased acne severity by roughly 26% through reduced sebum production. Less sebum = less Malassezia food. Practically, this means fewer refined carbohydrates, added sugars, and highly processed foods; more vegetables, whole grains, legumes, and lean proteins.

Consider zinc supplementation. Zinc (15–30 mg/day as zinc picolinate or gluconate) supports antifungal immune function. A placebo-controlled trial found zinc supplementation significantly reduced fungal infections alongside other clinical benefits. Don’t exceed 40 mg/day without medical supervision, and take it with food to avoid nausea.

Probiotics show real promise. Oral Lactobacillus paracasei ST11 produced a 57% improvement in dandruff severity versus 16% for placebo, with decreased scalp Malassezia counts.

Topical Lactiplantibacillus plantarum reduced M. furfur growth and inhibited its damaging phospholipase activity in lab studies (Lanza et al., 2023). Topical L. crispatus and L. paracasei applied to patients with seborrheic dermatitis showed notable reductions in Malassezia abundance.

While we need more research, incorporating a quality probiotic, both oral and potentially topical, is a reasonable and low-risk strategy.

Manage stress and sleep. Chronic stress impairs both immune function and skin barrier integrity, creating conditions favourable for fungal overgrowth.

This isn’t just wellness talk; the connection between psychological stress, cortisol elevation, impaired barrier function, and increased skin susceptibility to infections is well-documented.

Aim for 7–9 hours of sleep, and find stress management strategies that work for you.

The bottom line

Malassezia folliculitis is real, it’s common, and it’s dramatically undertreated because it’s so frequently misdiagnosed as acne. The clues are there if you know what to look for: uniform tiny bumps, itching, trunk and forehead distribution, and stubborn resistance to acne treatments.

Treatment works. Topical ketoconazole, zinc pyrithione, selenium sulfide, or ciclopirox olamine will clear most cases in 2–4 weeks. Oral itraconazole or fluconazole resolves severe cases in 1–2 weeks.

But the real work is what comes after: consistent maintenance with antifungal washes, barrier-supportive skincare, lifestyle modifications, and learning to catch flares early.

The “fungal acne safe” skincare movement deserves credit for awareness, but its all-or-nothing ingredient lists collapse under scientific scrutiny. Malassezia lipid metabolism is species-specific, concentration-dependent, and profoundly shaped by formulation context and individual host factors.

Squalane, MCT oil, caprylic/capric triglyceride, mineral oil, and ceramides are not your enemy. A barrier stripped of all lipids is actually more vulnerable to Malassezia than one supported with smart emollients.

Your skin doesn’t need fear-based skincare. It needs informed decisions, barrier support, targeted antifungal treatment when needed, and the understanding that healthy skin is about microbial balance, not ingredient elimination.

That’s it for this week. Let me know in the comments what your ‘fungal acne’ skincare strategy is. And please share this article with a friend who struggles with fungal acne.

Until next week, if there is a topic you would like me to explore in depth, please share your ideas.

Lots of love,

Marina
