The skin is the largest organ on our body and is comprised of the main layers with a multitude of sublayers. The three main layers of the skin are the Epidermis, the dermis and the subcutis. The epidermis is the top layer of the skin and the part of the skin that is visible to the naked eye. The dermis found beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue. It takes approximately 28 days for the skin to generate itself and for the cells to reach from the subcutaneous layer up up to the epidermis where it is sloughed off the body. The more hydrated you are the thicker the epidermis layer becomes which is generally only the thickness of a tissue comprised of 5 layers. Eating antioxidants and using natural products rich in antioxidants help protect our body's from damaging free radicals which not only age us but in excess can also eventually cause cancer.
When dealing with laser skin treatments laser treatments can reduce wrinkles, blemishes and scars by causing slight trauma to the below cells forcing them to produce collagen that we lose as we age. This is best treated in the dermis and subcutis layers of the skin and these are the layers of skin that are in charge of regenerating itself.
