In our reference data, Aluminum/Magnesium Hydroxide Stearate can feed Malassezia (fungal acne).
Aluminum/Magnesium Hydroxide Stearate is a metal-soap complex used in cosmetic formulations primarily as a thickener, gelling agent, and stabilizer, particularly in anhydrous or oil-based systems. It helps suspend pigments and control viscosity rather than providing a direct therapeutic skin benefit.
| Reported effect | How often | Notes |
|---|---|---|
| Mild skin irritation | Rare | Occasional transient redness or irritation, generally in sensitive individuals. |
| Contact allergy/sensitization | Very rare | Allergic contact dermatitis is uncommonly reported for metal stearate complexes. |
| Comedogenicity | Rare | Stearate-based ingredients may theoretically contribute to pore congestion in acne-prone users, though data are limited. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
