Cera Microcristallina (microcrystalline wax) is a refined petroleum-derived wax used in cosmetics as an emollient, thickener, and structuring agent that helps stabilize emulsions and bind oils. It is commonly found in lipsticks, balms, creams, and ointments to improve texture and consistency.
| Reported effect | How often | Notes |
|---|---|---|
| Contact irritation | Rare | Mild irritation may occur in sensitive individuals, though the ingredient is generally well tolerated. |
| Allergic contact dermatitis | Very rare | Rare sensitization reactions have been reported, typically linked to impurities rather than the refined wax itself. |
| Comedogenicity / pore occlusion | Uncommon | Occlusive properties may contribute to clogged pores or breakouts in acne-prone skin. |
