Skin Care Products

Before getting into the specifics of skin care, it's a good idea to understand the skin itself. The skin is made up of three main layers: the epidermis, the dermis, and the hypodermis. The hypodermis is the deepest layer and contains a layer of fat. It also houses the larger blood vessels and nerves.The dermis contains the smaller blood vessels and nerves as well as the hair shafts and the sebaceous glands. The sebaceous glands produce sebum, an oily substance that it secretes into the hair shaft. Sebum makes its way up to the top of the skin through the hair shaft, where it covers the outer layer of the epidermis thereby providing a protective barrier for the skin from exterior dangers. A small coating of sebum will protect the skin effectively. An excess of sebum leads to overly oily skin and can cause acne.
