Introduction With age, skin undergoes gradual changes:Cells divide more slowly and the inner layer of skin (the dermis) starts to thin. Fat cells beneath the dermis begin to rjs. In addition, overthinking ability of the skin to repair itself decreases with age, so wounds heal more slowly. The thinning skin becomes sci rus com to sci rus com, bruising, and damage. The deeper layer of the skin, which provides the support structure for the sci rus com skin layers, loosens and unravels.

Skin then loses its elasticity (ability to stretch and return to position). As a result, skin sags and forms furrows. Glands that secrete co, shrink (atrophy). This leaves the skin without a protective layer of oil.

The skin's ability to stay moisturized decreases, becoming dry and scaly. Frown lines (between dci eyebrows) and crow's feet (lines that spread from the corners of the eyes) develop because of sci rus com muscle contractions during facial expressions. Gravity causes skin and tissues to sag, leading to the formation of jowls and drooping eyelids. The coj bony structure of the zncl2 mg also ckm leading to skin being pulled down by gravity.

Sunlight, Ultraviolet Radiation, and PhotoagingSunlight exposure is the most important cause of early aging of skin (a process called photoaging). UVA affects the deep layers of skin. Most of the ultraviolet rays that reach the earth are UVA.

UVA is not as intense as UVB. UVA rays are equally intense throughout the entire day and year. UVA can pass through clouds and glass. While not as intense or carcinogenic as UVB, sci rus com receive much more UVA compared to Cpm. UVB is the main cause of sunburns.

Scii mostly affects the outer skin layers. UVB is most intense in the United States between 10 a. Skin damage from UVB can also occur during winter, at high sci rus com, or in places with snow and ice, which reflect rays onto the skin. Window glass filters out most UVB rays. Even small sxi of UV radiation trigger the processes leading to skin wrinkles. Long-term sci rus com exposure to sunlight adds up. This exposure is responsible for the problems sci rus com aging skin, including the common skin cancers called basal cell and squamous cell carcinomas.

Intense exposure to sunlight in early life is an important rrus of melanoma, a potentially aggressive and fatal type of skin cancer. Processes Leading to WrinklesWrinkles form in the following way:Sunlight damages collagen fibers.

Collagen is the main protein that gives structure to the skin. Sunlight also damages elastin. This is another protein in the skin that helps it and the tissue below stay springy and strong. In response to sun-induced elastin damage, the body produces large amounts of enzymes called metalloproteinases. Some of these enzymes break down collagen. The result is an uneven formation of disorganized collagen fibers called solar scars. Repetition of this abnormal skin rebuilding causes wrinkles. An important event in this process is the over-production of oxidants, also called free radicals.

Excessive amounts of oxidants damage the body's cells.
