The Proderm skincare system consists of mousse formulations that are scientifically developed to gently treat and prevent a range of minor skin disorders. Proderm has been designed to be a soft, non-greasy mousse that's easy to apply, and gentle on skin. Proderm contains palmitic and stearic acid, which are two natural lipids found in the composition of human skin. The unique lipid/water formulation restores the skins natural moisture balance which, in turn, helps to protect the skin, without destroying the skin barrier as some topical drugs do. This special formulation penetrates deeper into the epidermis (outer layer) of the skin to give maximum protection and moisturisation.
The barrier function of the skin is vital for controlling loss of moisture from the body and also protects against external substances entering the body. The upper layer of the skin consists of 85% lipids (ceramides and fatty acids) and 15% water. If this composition if lipids and water becomes disrupted, the protective barrier function of the skin becomes compromised. If you imagine the structure of the skin to be similar to a brick wall, the lipids are the mortar between the bricks (skin cells), which hold the structure together. Obviously, if the lipids (or mortar) are lost, the structure becomes unstable. This results in excess moisture loss from the body which perpetuates the condition. It also renders the barrier function of the skin ineffective, which allows external irritants to be more readily absorbed into the skin. When you experience irritation, it's because there are tiny breaks in it that are causing inflammation. What Proderm does is to quickly penetrate your skin and fill any small tears with soothing lipids. The result? Completely non-greasy moisture replenishment that repairs the natural barrier function of your skin.
