In depth
What it does
A plant oil pressed from flax (linseed) seeds, rich in omega-3 fatty acids, used as a nourishing emollient in skincare formulas. As an emollient ingredient, it is particularly valued for rich in omega-3 alpha-linolenic acid, nourishing, barrier-supporting emollient, and softens and conditions skin.
Skin type guide
Best suited to normal, dry, or combination skin. Lightweight emollients work for oily skin too — richer ones are best reserved for dry and very dry skin types.
How to use it
Works best as a later step in your routine, after water-based serums and treatments. Emollients help seal in earlier layers, so their placement matters — put lighter textures on first.
