First a bit about skin: The main function of the skin is to provide a barrier between the body and outside environment. Think of it like a brick wall. The Bricks are the corneocytes (dried out, non-living cells on the skin’s surface that are ready to shed). The Mortar is an intercellular matrix composed of lipids (fatty acids, hormones that help maintain skin hydration, firmness and softness) surrounding the corneocytes.The Paint on the wall is the acid mantle on the surface of the skin, a physical and chemical barrier that keeps out microorganisms and irritants.
So let's talk Moisturizing. When the skin’s barrier function is damaged, it needs repairing and strengthening. This involves replacing the lipids in the skin that have been depleted or removed. Barrier repair ingredients are typically rich in lipids that are similar to the intercellular lipids found in skin. And guess what...beeswax and Plant Oils and waxes have been used over centuries for this purpose because they are a good source of fatty acid lipids. They are also protective, providing a temporary film over the skin to help it retain moisture. Yep, our grandmothers certainly knew what they were doing!
Now on to Hydration. While moisturizing ingredients seal moisture into the skin, hydrating ingredients help increase the water content of the skin. A humectant, for example, has the ability to attract water from the air and bind it to the skin’s surface, facilitating hydration. And plant extracts can also bring water, minerals and vitamins to skin.
