Importance of skin care?
Of all the body's organs, the skin is the most versatile. It is the only organ that is directly and constantly open to the outside world. Skin protects against external agents, heat and cold, air and the elements, and bacteria. It is waterproof, repairs and lubricates itself, and even eliminates some waste products from the body.
Like its relatives, hair and nails, it reflects both physical and mental health. Skin can warn of internal illnesses with changes in color or texture, with the appearance of spots or blemishes. It provides our sense of touch and can be rough or delicate, smooth or wrinkled, depending on our needs or age.
It can prickle, blister, tingle, itch, ache, sweat, stretch, shrink, bleed, and blush. Skin contributes to the production of vitamin D, vital for healthy bones and joints. It controls body temperature. It can display emotions, is a source of social and sexual attraction, and denotes racial origin. "The skin of an average adult covers almost two square meters and weighs more than two and a half kilos."
