Ceramides in skin care are especially beneficial for skin over 40. Skin care products containing ceramides help replenish the skin's ceramide deficiency, so the skin starts to look and behave like a younger version of itself, and stays better hydrated, firm and plump.
Ceramides occur naturally in the skin and make up around 50% of our skin's composition. Ceramides are lipids that act like a grout between tiles; they bind the gaps between skin cells together and prevent moisture from escaping. In addition, ceramides keep your skin cells in the right order, which helps water stay inside the skin and on the other hand prevent pollution, bacteria and free radicals from entering.
