Lipids such as ceramides, cholesterol, and fatty acids are key components of the skin's barrier that help reduce transepidermal water loss and maintain hydration. In skincare they restore and reinforce the stratum corneum barrier, improving skin softness and resilience.

Allergic contact dermatitis | Rare | Can occur with specific lipid sources (e.g., lanolin, certain plant oils). |
Folliculitis | Very rare | Occasionally associated with heavily occlusive lipid-rich products. |
