Can the dark skin from my second degree burn go away?

Hyper pigmentation: If your burn is recent then it is likely to fade with time. The deeper the burn, the longer the Healing phase. Some folks tend to hyper pigment more than others and sun exposure while healing can make it worse. There are treatments for hyper pigmentation (laser, bleaching type creams). However if the burn scarred the skin then it is more difficult and may require excision.
