People get wrinkles for a number of reasons, some of which include sun damage, smoking, dehydration and certain medications, according to Medical News Today. Wrinkles are a natural aspect of the aging process as the skin becomes thinner and less elastic.
Wrinkles occur naturally as skin gets older. The wrinkles are the result of creases, or folds, that appear as skin loses its elasticity, moisture and thickness. Wrinkles can also occur from spending lots of time in the pool as the water dehydrates the skin. Usually wrinkles first appear on the face from facial expressions. Genetic factors also play a significant role in how someone's skin ages and in what areas wrinkles start to appear. The most common areas on the body that wrinkles form on are the palms, face, neck and the tops of the forearms.
There are two main types of wrinkles, referred to as surface lines and deep furrows. Anti-aging creams and cosmetic products can reduce these fine lines, but deep furrows usually require more aggressive treatments, such as plastic surgery or Botox injections.
Sun damage plays a major role in why some people get wrinkles sooner than others. People who have light skin tend to receive much more skin damage from the sun, so this accelerates the aging process. People who smile a lot also get wrinkles. People who never wear hats or long-sleeved shirts tend to wrinkle sooner. Smoking is another factor which leads to accelerated aging of the skin.
