    Flax Seed Extract

    Also seen as: Linum Usitatissimum Seed Extract
    All ingredients

    What it does

    A botanical extract rich in lignans, omega-3 fatty acids, and antioxidants. Supports skin barrier, soothes irritation, and provides anti-inflammatory benefit.

    Best for

    Sensitive or compromised skin, neck creams, and formulations targeting visible firmness via barrier support.

    The full picture

    Flax seed extract delivers a profile of lignans, alpha-linolenic acid (an omega-3), and polyphenolic antioxidants. In skincare formulations it is typically a supporting active for barrier support and soothing rather than a hero anti-aging ingredient. Found in ALASTIN's Restorative Neck Complex alongside the brand's flagship TriHex peptide technology, where its role is to complement the peptide work with barrier and comfort benefits.

    Evidence

    A supporting botanical valued for lignans and omega-3 fatty acids, used mainly for barrier support and soothing. Robust independent clinical evidence specific to the topical extract is limited.
