Ceramides are fatty acids and sphingosine that connect skin cells and form a protective barrier. They naturally decrease with age, exposure to environmental damage. Using topical ceramides provides nourishment and protects against infections. Products containing ceramides like ceramide AP, NP, EOP, NG and NS are suitable for all skin types and have anti-aging benefits. Including ceramides in skincare, especially from mid-thirties onward, replenishes the skin's barrier and fights signs of aging.
