General Functions of Your Skin

Defense Skin features a protective function by virtue of its ability to endure physical influences: Due to the smooth, resistant, and elastic covering and its particular fatty hypodermic region, the skin has the capacity to absorb external shocks and pressures. Withstand chemicals and water: The horny cells, keratin, fatty tissues, and sebum of the skin prevent excess water, liquids, or chemicals from infiltrating. Control injuries and bacterium: The skin’s immediate and constant regeneration of cells and its acidic pH enable it to safeguard the body from injuries and microorganisms. Protect against the sun or ultraviolet radiation: Your skin affords defense against these elements with the aid of the horny layer, keratin and melanin, which rise from the basal cell layer toward the upper layers and tan the skin to avoid sunburns. Sebum and sweat also defend our bodies against ultraviolet and infrared radiation.

Respiration In people, the tissues of the skin, like all other tissues, breathe. (Oxygen is absorbed and carbon dioxide is expelled.) However, skin respiration is extremely weak.

Temperature Regulation One of the most important functions of the skin is its chance to regulate your body’s temperature. When the body becomes overheated, that is, once the internal temperature is elevated, vasodilation happens in your skin. This increases the quantity of blood circulating (giving the skin higher color) as well as the amount of perspiration secreted. In the event the temperature is too low, vasoconstriction happens. Then the diameter of the capillaries decreases by contraction. Less blood is passed, skin color fades, and perspiration decreases. These processes permit the body to save its warmth and protect itself against cold and therefore are responsible for skin reddening when hot and becoming white in the cold.

Secretion External. Your skin, through the secretions of the sweat glands, helps rid the waste. The sebaceous glands, which create a secretion called sebum, force out harmful substances. Internal. Skin secretes enzymes, fermentation substances, hormones, and so forth, which take part in nutritional exchanges. The most important hormone secreted by the skin is histamine (a tissular hormone which produces allergy symptoms).

Absorption Absorption is the most important part of the nutrition process. Since the skin is impermeable, it is crucial for your esthetician to find out how to avoid all the obstacles to skin penetration.

Regeneration To the other functions on the skin, you can also add that of cellular renewal, for the beauty and freshness of your skin rely on the rate with which it can regenerate itself (approximately 30 days). Renewal happens within the basal cell layer. All of the cells in this layer divide in half: One of the two new cells remains in the same position whilst the other travels to the next higher layer. Sooner or later, as the cell ages, it reaches the horny layer where it is eliminated by the desquamative layer.

Bactericidal Action Your skin is continuously touching microorganisms. Since the skin is acidic (i.e., it features a pH that varies from around 5.4 to 6.2), it effectively blocks most microorganisms from entering. That is why it’s always essential in esthetics to respect and maintain the skin’s acidic pH.

As you age, your skin becomes less able to renew itself. Using a good wrinkle cream helps prevent wrinkles.
