Although multiple factors contribute to premature senescence, aging itself can be divided into different categories. Genetics can play a role with how well the skin ages over time. A poor diet, alcohol, and stress can lead to the early damage to the skin. The environment can cause damage to your skin such as exposure to pollution, and too much sun will damage the skin which is called photo aging. All of these factors can cause the loss of subcutaneous support of the fatty tissue between your skin and muscle.
Many individuals suffer from discoloration of the skin or unevenness of the color of the skin. Some of the more common causes for changes in skin color are illness, injury, and inflammatory problems. Discolored skin patches also commonly develop in a certain part of the body due to a difference in melanin levels. Melanin is the substance that provides color to the skin and protects it from the sun.
Melasma (muh-LAZ-muh) is a common skin problem that causes brown to grayish-brown patches that can appear on multiple areas of the body. Most people get it usually on the face, their cheeks, bridge of their nose, forehead, chin, and above their upper lip.
Scars occurs when the dermis is damaged by injury, surgery, from acne or scab picking. Dermis sends out fibroblasts, cells that produce collagen, to begin rebuilding tissue immediately. In a rush to repair itself there may be either too much collagen creating a raised Keloid scar (Hypertrophic), or a lack of collagen leaving an indent (Atrophic) like the divot scaring from chickenpox. A scar is an area of fibrous tissue that replaces normal skin after an injury. Scars result from the biological process of wound repair in the skin, as well as in other organs and tissues of the body. Thus, scarring is a natural part of the healing process.
