Emollient / Occlusive Hydration & Barrier

What it is & what it does

Lanolin is a waxy emollient and occlusive derived from wool.
It is excellent at reducing water loss and softening very dry, rough skin, which is why it is common in protective balms. Lanolin allergy exists, particularly in people with chronic dermatitis.

Usage & cautions

People with a confirmed lanolin allergy should avoid it.
Information approach Consumer-friendly summaries are informed by established cosmetic ingredient references such as INCIDecoder and Paula’s Choice Ingredient Dictionary, while avoiding turning ingredient-level evidence into medical claims about the finished product.
