Stretch marks appear when there is an intense and rapid stretching of the skin, with rupture of the collagen and elastic fibers. This often occurs in gestation, puberty (by rapid growth) or body weight variation. Some medicines for oral or local use may also cause stretch marks, such as corticosteroids.
The treatment of stretch marks should be started as soon as they appear and are red, as they respond much better at this stage compared to those that are already whitish. Fractional CO2 laser, pulsed intense light, diamond peeling (skin exfoliation) and retinoic acid peeling, often combined, can be used for better and faster results. All these methods aim to stimulate the collagen and elastic fibers, reducing the size and improving the color of the striae, making them more discreet.
