Ceresin is a refined microcrystalline wax derived from ozokerite (a natural mineral wax) used in cosmetics as a thickening, stabilizing, and emollient agent. It helps control viscosity and improve the texture and stability of emulsions, sticks, and balms.
| Reported effect | How often | Notes |
|---|---|---|
Contact dermatitis / skin irritation | Rare | Generally considered non-irritating; irritation is uncommon and often related to impurities or accompanying ingredients. |
Allergic contact sensitization | Very rare | Isolated case reports; ceresin is widely regarded as having very low allergenic potential. |
Pore-clogging / comedogenic effects | Rare | Heavy waxes may occasionally contribute to follicular occlusion in acne-prone individuals, though ceresin is typically low on the comedogenic scale. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
