OUR SKIN TO AGE 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 photoaging. All of these factors can cause the loss of subcutaneous support of the fatty tissue between your skin and muscle.
The loss of the elastic tissue (elastin) in the skin with age causes the skin to hang loosely. … This is caused by thinning of the epidermis (surface layer of the skin). Skin becomes more fragile. This is caused by a flattening of the area where the epidermis and dermis (layer of skin under the epidermis) come together thus causing wrinkles.
