- 1). Talk with a dermatologist about topical treatments that can lighten the darkened areas. Common ingredients include hydroquinone, tretinoin (derived from vitamin A), corticosteroids, azelaic acid or glycolic acid. Your doctor might recommend using a combination of topical agents for optimal results. Follow your doctor's instructions regarding proper use and do not apply the treatments in larger amounts or with greater frequency than recommended.
- 2). Certain dermatological procedures can normalize skin color; they include chemical peels with agents like glycolic acid, trichloroacetic acid, laser resurfacing, and cryotherapy, which employs the use of liquid nitrogen. You will need to commit to several sessions to achieve maximum benefit.
- 3). Wear a sunscreen of at least SPF 15 daily, regardless of the season, if the area of hyperpigmentation is not covered by clothing. This will keep already darkened skin from getting darker.
