Stretch marks are thin, linear scars that develop in males and females after rapid growth. It is a very common condition that can be very distressing, but is usually only of cosmetic concern. Stretch marks commonly occur in boys and girls during puberty, where there is rapid growth and weight gain, and during pregnancy. Bodybuilders, especially if they take steroid drugs can develop stretch marks.
The most effective treatment for stretch marks is the fractional laser. The laser's energy penetrates into the dermis and stimulates fibroblasts and the production of new collagen. The new collagen thickens the skin of stretch marks to make it more closely resemble normal skin. It also improves the red discolouration of new stretch marks. A series of treatments are usually necessary and results are excellent.
