Cholesterol is a naturally occurring lipid found in the skin's stratum corneum that, alongside ceramides and fatty acids, helps maintain the skin barrier and prevent transepidermal water loss. In skincare formulations it functions as an emollient and barrier-repair agent that improves hydration and skin resilience.
| Reported effect | How often | Notes |
|---|---|---|
| Mild contact irritation | Rare | Occasional redness or stinging, more likely in sensitive or compromised skin. |
| Allergic contact dermatitis | Very rare | Isolated reports; cholesterol is generally well tolerated and non-sensitizing. |
| Comedogenicity / clogged pores | Rare | Low comedogenic potential, but possible in acne-prone individuals at high concentrations. |
