Hydroxystearic Acid
May feed Fungal Acne
Fungal acne-safe products avoid ingredients that feed Malassezia yeast, the cause of fungal acne. Unlike regular acne, fungal acne appears as small, uniform bumps and won't respond to typical acne treatments. If you suspect fungal acne, consult a dermatologist for proper diagnosis.
Explained
Hydroxystearic Acid (HSA) is a wax-like fatty acid. It is a surfactant, emollient, and emulsifier.
Surfactants are cleansing ingredients. They reduce the surface tension of dirt and grime to be removed easily.
HSA is an emulsifier in certain formulations. Emulsifiers prevent ingredients from separating.
This ingredient may not be Malassezia folliculitis, or fungal acne, safe.
