Do you know what the largest organ in our body is? Human skin is actually our largest organ in the body. Not surprisingly, it can cover up to a surface area of 2m. We are covered entirely with it. Our skin is very important in the way that it gives the first impression to people when we see each others’ face. Do you ever have problems like dry skin or acne? Understanding more about this vital organ in our body can help us to take good care of it and choose the right skincare to maintain our glamorous skin.
Some of the functions of Normal Skin Structure
The skin is very important to us. It offers protection for us from harmful external stimuli such as UV, micro-organisms, and allergens. The skin consists of three layers, namely the epidermis, dermis and subcutaneous tissue. All three of these layers play a role in the normal skin functions. The epidermis is the outermost layer and is the thickest layer among the three. It mainly contains special skin cells called corneocytes which act to form the “barrier” for our body against the environment outside.
The dermis beneath the epidermis is a layer of connective tissue with most of the collagen and elastic fibers to give strength and toughness to our skin. The deepest layer is the subcutaneous tissue which contains loose connective tissue and fat. The fat stored in this layer offer some insulation to our body to keep our skin warm all time. Also, the blood vessels in the skin mainly are present in the subcutaneous tissue.
