 Skin aging is a fact of life; everyone will face it sooner or later. In order to understand how this process works, it is important to know the basics of skin. The epidermis, dermis, and subcutaneous tissue are the three layers that compose the human skin.1. Epidermis is the skin’s surface, a layer rich in keratin that provides toughness and water-resistance. This layer of skin is where dead cells are shed and where melanin (a dark pigment) is found. 2. The second and thicker layer is the dermis, which is composed of nerves, fats, blood vessels, elastin, and collagen fibers, which provide elasticity. 3. The third layer is composed of fat, keeping us warm and is the one on contact with our internal organs.There is an aging process that takes place over the years regardless of external influences. – After the age of 20, one percent less of collagen is produced in the dermis each year. The collagen and elastin fibers become thicker, more clumped, and looser, resulting in inelastic and brittle skin and eventually in wrinkling and sagging.  – In our 20s, the skin’s exfoliation process decreases by more than 20%, causing dead skin cells to accumulate and stick together for longer periods of time.– In our 30s, the transfer of moisture from the dermis to the epidermis is slowed and fat cells start to shrink. These effects make the skin look dull and thin.– In our 40s, collagen is no longer produced. The collagen and elastin fibers break, thicken, stiffen, clump together, and lose their elasticity. This results in wrinkles and aging lines. – In our 50s, the skin becomes dry and is easily bruised, damaged, or broken because the oil glands have decreased in size. In women, menopause causes a decrease in estrogen levels, leaving the skin drier, thinner, more sensitive, and less toned. |
 A second type of aging is an aging provoked by environmental damage and it can be controlled. Some examples are: Thickening of the external layer of epidermis, precancerous changes, freckles and sunspots, and huge losses of collagen, elastin, and other important elements. As a result of these processes, the skin becomes rough, with uneven tone, and wrinkled.Free radicals (electron-hungry molecules or atoms) are the cause of these chemical changes. Some of the environmental influences generating free radicals are pollution, smoking, and ultraviolet radiation. Antioxidant enzymes and molecules, such as vitamin C, vitamin E, and carotenoid pigments, can protect us from free radicals. Glucose, a fuel necessary for our bodies, presents another threat.
