Waxing scars can be both embarrassing and difficult to get rid of--especially if they are in a very noticeable area, such as on your lip. Waxing has become a popular way to remove hair but it also can produce burning and scarring if not done properly. If you have a scar from waxing, however, there are treatments available that can help to reduce its appearance.

Purchase an over-the-counter lotion or cream containing alpha hydroxy acid and apply it to the scar. Products containing milder concentrations of AHA are preferred. AHA forces the skin to exfoliate, removing old layers of dead skin cells and bringing new, healthy skin cells to the surface. AHA can cause skin irritation, so do not apply this product to the scar site if you have a sunburn in that area or any kind of thermal or chemical burn caused by waxing.

Apply silicone gel or silicone sheets to your scar. While it's unknown exactly how silicone helps to fade the appearance of scars, some medical experts and researchers think it works by creating static electricity, which helps to flatten and smooth the scar, increasing blood flow to the area.

Talk to a dermatologist about your wax scar. He can suggest a possible method of scar removal appropriate for your type of scar. He also may be able to perform a number of procedures, including microdermabrasion, collagen injections, chemical peels, or fat transfers, in order to reduce the appearance of your scar. Also consider talking to a board certified plastic surgeon about laser scar removal, a cosmetic procedure which resurfaces the scar area using high-powered light.

Apply onion extract to the scar. While onion extract may not completely erase the appearance of your wax scar, according to a 1994 study published in the International Journal of Clinical Pharmacology Research, researchers found that onion extract was more effective in reducing the appearance of scars than using no scar removal treatment at all. You can buy onion extract in gel form, or you can purchase a scar removal product containing onion extract. You will need to reapply the gel to the scar for a number of months for it to be effective.
