Stretch marks are tears that occur in the deepest layers of the skin. They are caused by a lack of collagen and elastin during periods of intense growth, such as pregnancy and growth spurts in adolescence. They affect the belly and breasts (in pregnant women), arms, shoulders, hips, thighs and buttocks. Studies also suggest that stretch marks are linked to hormonal changes. In fact, the hormonal imbalance that occurs during pregnancy and puberty notably reduces the production of collagen and elastin. The skin loses its elasticity.
The color and appearance of stretch marks differ. There are 2 types :
- Red stretch marks (striae rubra), inflammatory: following the stretching of the epidermal layer, the blood vessels of the dermal layer become visible.
- White stretch marks (striae alba), mature: they appear where the blood vessels have faded. Their silvery-white color is due to the fat that lodges under the epidermis..
Stretch marks are permanent scars. However, innovative treatments can reduce the appearance of stretch marks. During the consultation, your doctor will recommend the appropriate treatment for your type of stretch marks.
