Stretch marks are caused by rapid weight loss or weight gain, often due to pregnancy. Though they may be unsightly, stretch marks are not a health concern. Topical creams and various cosmetic procedures have been known to dramatically improve the appearance of stretch marks, though they may not be able to get rid of the marks completely.
Tretinoin
The Mayo Clinic suggests that tretinoin, a vitamin A derivative often used to treat acne and aging skin, may be helpful in treating stretch marks. Tretinoin cream is available by prescription only and is most effective on young stretch marks that are "less than 6 weeks old." Tretinoin is applied topically and works by removing damaged layers of the skin and promoting collagen growth. Do not use this medication if you are pregnant.
Laser Therapy
There are three types of laser treatment for stretch marks, according to the Mayo Clinic, and they are excimer laser, pulsed dye laser therapy and fractional photothermolysis. Excimer laser treatment works by targeting the discoloration in the stretch marks to remove the excess pigmentation and make the stretch marks blend into the surrounding skin. It is best used on older stretch marks that have begun to fade. Pulsed dye laser therapy works by promoting the growth of collagen and elastin, thereby healing the damaged layer of dermis. It works best on newer stretch marks. Fractional photothermolysis is similar to pulsed dye laser therapy in that it also works by stimulating collagen and elastin growth.
Microdermabrasion
Microdermabrasion is a popular skin resurfacing treatment that can also improve the appearance of stretch marks. The treatment involves a machine that uses a diamond-tipped wand to gently slough off the damaged layers of the skin. Like tretinoin and some laser therapies, it also promotes collagen growth to replace the damaged skin. Several treatments may be necessary to obtain optimal results. Microdermabrasion is often done at a plastic surgeon or dermatologist's office. Recovery is generally quick with little to no downtime.
