Highest-evidence picks
Hyaluronic Acid
Natural polysaccharide that binds water up to 1000 times its own weight. Topical application creates a surface humectant effect without dermal penetration.
Glycerin
The simplest trihydric alcohol and one of the most common humectants in cosmetics. Draws water from the environment and retains it in the stratum corneum.
Dimethicone
Silicone polymer that forms a protective film on the skin to lock in moisture. Gives products a silky texture and does not penetrate the dermis.
Urea
A natural moisturizing factor (NMF) present in the stratum corneum. Low concentrations moisturize; high concentrations act as a keratolytic. The gold standard for hyperkeratosis and xerosis.
Niacinamide
Vitamin B3 form with a wide action spectrum: brightens pigmentation, strengthens the barrier, minimizes pores, and reduces sebum production.
Salicylic Acid
Beta-hydroxy acid (BHA) with lipophilic properties: penetrates sebaceous glands, dissolves plugs, and exerts anti-inflammatory effects.
What to know
Malassezia folliculitis (often called «fungal acne» online) looks like uniform 1 to 2 mm itchy papulopustules on the forehead, chest, and upper back. The pathogen is a lipid-dependent yeast – Malassezia globosa and M. furfur – that feeds on fatty acids with chain lengths between C11 and C24. This narrow metabolic window dictates the entire skincare strategy: every ingredient that yeast can digest will worsen the rash, regardless of how «gentle» it is for normal skin.
Ingredients to avoid: olive, coconut, jojoba, argan, almond, avocado oils, isopropyl myristate, isopropyl palmitate, polysorbate 60 and 80, oleic acid, stearic acid, lauric acid, cetearyl alcohol in some formulations, ester-heavy emollients. Esterified vitamin E (tocopheryl acetate) is debated but most clinicians flag it. Fermented ingredients (galactomyces, lactobacillus ferments) feed the yeast and provoke flares.
Safe and active ingredients: ketoconazole 2% (prescription in EU, OTC in US shampoos), ciclopirox olamine, zinc pyrithione 1 to 2%, selenium sulfide 2.5%, climbazole. These act directly on the yeast and clear papules within 2 to 4 weeks of daily use as a leave-on or 10-minute shower mask. Glycerin, propylene glycol, butylene glycol, hyaluronic acid, urea, panthenol, niacinamide, allantoin, and silicones (dimethicone, cyclomethicone) are all safe humectants and emollients. Squalane is the one «oil» that yeast cannot metabolise because it lacks the right ester structure – it became the standard fungal-acne-safe emollient.
Practical routine: gentle non-ionic cleanser, an anti-fungal active (Nizoral or Stiefel Skinoren style product) left on the area for 5 minutes, then a humectant-only moisturiser based on glycerin and hyaluronic acid. Sunscreen options are limited – Purito Daily Soft Touch, Beauty of Joseon Relief Sun, and certain mineral SPFs without fatty alcohols work for most patients.
Frequently asked
How many fungal acne safe ingredients are in the Evigrade database?
Evigrade currently tracks 18 ingredients in the «fungal acne safe» category. Of those, 15 carry evidence tier A or B.
Which fungal acne safe ingredients are safe during pregnancy?
15 ingredients in this category are flagged as safe during pregnancy at typical cosmetic concentrations. Always confirm the choice with an OB-GYN.
Which ingredients suit sensitive skin?
15 ingredients in this category show both low irritation potential and low allergen risk, making them safe even for reactive and sensitised skin. A patch test is still advisable before first use.
How should I start using ingredients from this category?
Start with a single high-evidence ingredient (tier A or B) at a low concentration, 2–3 times per week. After 2–3 weeks without reaction, frequency can be increased. Do not introduce two new actives at once – if skin reacts, you won't know which one caused it.
