Skin health is maintained by an oily (waxy) solution called sebum; 25-30% of the skin's sebum is made up of wax esters. The prime role of wax esters is to hold moisture in the skin, which keeps skin looking and feeling firm. As we hit our early 20's, our production of wax esters starts to decrease, allowing moisture to escape from skin cells. This begins the aging process of skin. Jojoba is the only plant known to produce wax esters similar to those in our skin. Jojoba is naturally hypoallergenic and contains powerful antioxidants, Omega 6 & 9 fatty acids, and Vitamins A, D and E. Remarkably, when applied to skin, the wax esters in jojoba provide similar nurturing and moisturising properties as our own sebum. Skin recognises jojoba as its own and lets it in to deliver active ingredients into the deeper layers of our skin.
