This is the term used to describe the outer layer of skin, which acts as a barrier between the body and the environment. The Epidermis varies in thickness, from very thin under the eyes to quite thick on the palms and soles of the feet. Different areas may also contain hair follicles, nails, sweat and sebaceous glands. The epidermis is constantly renewing itself, shedding dead and damaged skin cells each month to reveal new, smoother skin.
The majority of skin care products only penetrate as deep as the Epidermis. For products to make a long-lasting difference to the condition and look of the skin, they need to go much deeper. Collagen, Elastin and Hyaluronic Acid are all present in the Epidermis, with natural levels decreasing as the body matures, which is what causes the skin to show age and obvious signs of damage.
