السيراميدات

Ceramides are lipids that occur naturally in skin — they make up much of the barrier that keeps moisture in and irritants out. As we age, and under environmental stress like sun and AC, ceramide levels fall, and the barrier weakens: skin becomes drier, more reactive, more easily irritated. Ceramide skincare replenishes what's lost. It suits dry, sensitive and mature skin especially, and there's no wrong way to use it . In a moisturizer or serum, morning and night. Ceramides work best alongside other barrier-supporting ingredients like hyaluronic acid and ectoin. For skin that needs barrier focus, see Sensitive Skin and Dry Skin.
