Treatment

Treatment of hyperpigmentation may include hydroquinone, kojic acid, azelaic acid, ascorbic acid, tretinoin (Retinol), topical glucocorticoids, and licorice extract. Note that all treatments will fail if the affected area is exposed to the sun and if there is not adequate UVA/UVB protection.
