Barrier lipid
Lipids naturally found in the skin's barrier that hold cells together and seal in moisture.
Replenish the barrier, reduce moisture loss, and help skin feel calm and resilient.
Moisturizers, barrier creams, cleansers; often combined with cholesterol and fatty acids.
Dry, sensitive, compromised-barrier, and post-treatment skin.
Very well tolerated; ideal after exfoliants, retinoids, or professional treatments.
They do not exfoliate or 'resurface' — they protect and repair.
Pair well with hyaluronic acid, niacinamide, and gentle actives to buffer them.
Explain as 'mortar between bricks' — the seal that keeps hydration in and irritants out.
