While it's true sun spots are not usually cancerous, you should see a doctor about any irregular spots on your skin or any dramatic changes in the way your skin looks or feels. Never assume that a sun spot is benign, and always consult a physician before pursuing any course of therapeutic action.
Once you've got a diagnosis, you have a range of treatment options for sun spots, including several prescription and over-the-counter drugs, as well as a variety of dermatological procedures. Laser therapy, for example, destroys the cells that produce the extra pigment, while cryotherapy, or freezing, destroys the extra pigment itself. Dermabrasion and chemical peels both involve removing the top layer of damaged skin so that a healthy new layer can grow back [source: Mayo Clinic].
If these sorts of treatments seem too costly or labor intensive, you can take a topical approach instead. Look for solutions that contain hydroquinone; some cosmaceuticals contain it, too. Hydroquinone prevents the overproduction of melanin and runs interference for new skin cells, allowing them to develop and eventually mask -- or "fade" -- the damaged areas [source: My Skin Care Connection]. Kojic acid and tretinoin solutions have also been used to treat sun spots -- although not as successfully as solutions with hydroquinone -- as has the antioxidant vitamin, retinol.
If you don't buy the hype about pricey skin repair regimens, there are some other ways to treat sun spots. Read on to find out which all-natural methods could get your skin glowing again.
