Skin is the largest organ of the body, which acts as the first barrier against many harmful external factors. Knowing your skin type is the first step toward beautiful and healthy skin. It also helps in choosing proper skin care products.

The skin has different layers:
The uppermost layer of the skin is the epidermis, it acts as a physical barrier to prevent entrance of bacteria and to prevent water vaporization from the skin.
The dermis is right below the epidermis and is composed of elements that are responsible for skin toughness and elasticity.

There are five main skin types, which are: normal, dry, oily, combination and sensitive skin; also note that usually male skin is more abundant in collagen; so it is about 20% thicker than female’s, it is also oilier with larger pores and has a richer blood supply.

Human skin tone ranges from almost colorless to almost black. Knowing the skin tone helps in understanding skin’s reaction toward sun and choosing the best sun protection program. In addition, it is important to know the skin tone when seeking for cosmetic procedures.
