In general, hypopigmentation is incredibly difficult to treat, often with little to no success. There have been some documented cases of some treatment success using psoralens, tar, and lasers to stimulate melanogensis and repigment the areas. Ultraviolet therapy and phototherapy are effective against vitiligo. It treats the depigmented areas with a narrowband UVB light. Laser treatments can cause hypopigmentation, but have cured it, as well. The type of laser treatment needed will depend on the cause. Antifungal creams can be effective against tinea versicolor. However, more data and additional treatment options are needed to address this difficult-to-treat condition.
