According to Shellie Goldstein, founder of the AcuFacial, Skin can be defined as an organ comprised of layers of tissue that cover and protect muscles and vital organs of the body. There are three primary layers of skin:
- Subcutaneous Layer - the deepest layer which is made up of fat, blood vessels, nerves and cells.
- Dermis - the middle layer which is made of collagen (90%), elastin (5%), nerve receptors, sweat glands, hair follicles and blood and lymph vessels.
- Epidermis - the top layer which is made of many layers of cells that contain water, and eventually rise to the surface. As cells reach the top, they begin to dry out and die. The very top layer is called the Stratum Corneum. This layer contains dead cells which help protect the other layers.
As we age, it takes longer and longer for our cells to migrate to the surface. Skincare products affect the epidermis layer of our skin; however, it is believed that it is the activity that occurs in the dermis layer our skin that determines its health. Healthy skin looks and feels dewy—not red, blotchy or full of blemishes.
