In our reference data, Palmitic Acid & Stearic Acid can feed Malassezia (fungal acne).
Palmitic acid and stearic acid are saturated fatty acids used in skincare as emollients, thickeners, and emulsifying or co-surfactant agents to stabilize creams and provide a smooth, conditioning skin feel. They are generally considered safe, well-tolerated base ingredients rather than therapeutic actives.
| Reported effect | How often | Notes |
|---|---|---|
| Comedogenicity (clogged pores) | Uncommon | Palmitic acid in particular is rated mildly comedogenic and may contribute to breakouts in acne-prone individuals at higher concentrations. |
| Mild skin irritation | Rare | Occasional redness or stinging, more likely in sensitive or compromised skin. |
| Allergic contact dermatitis | Very rare | Sensitization to fatty acid components is infrequently reported in patch-test literature. |
