Wrinkles are folds that appear in your skin. They are found in the body parts that are predominantly exposed to the sun.
Genetics mainly determine your skin structure but there are other external factors that lead to wrinkling of your skin which are discussed below;
As you grow, the skin stops producing natural oils which initially provided nourishment for the skin. The fatty layer in the bottom part of the skin (dermis) diminishes leading to the formation of more pronounced wrinkles.
2. Exposure to ultraviolet (UV) rays.
UV rays break collagen and elastin fibres in the skin which form connective tissue that supports the skin elasticity. Interference of this tissue leads to wrinkling of the skin.
People who are involved in outdoor sports and activities are more likely to develop wrinkles earlier.
A poor diet involving much-processed food affects your skin negatively. Foods such as oily fish, fresh fruits and vegetables are required to maintain a supple skin since it contains the required nutrients.
4. Smoking.
Every drag you take pulls away the purse-string muscles causing premature wrinkles in your face. The addictive substance in cigarettes, nicotine, causes the narrowing of blood vessels in the upper layer of the skin. This leads to the formation of wrinkles since the skin is unable to get sufficient nutrients and oxygen.
