What products can be used to heal a burn/blister from using hydroquinone 4%? (photo)

In April 2016, I had a mole removed/frozen from my nose, but received a dark scar from the the procedure. Dermatologist prescribed hydroquinone 4% in October 2016, and as of February 2017 I've experienced darker pigmentation. The area is very similar to a blister and instead of lighting up, it's darker around the area. Is bio-oil, coconut oil or viatamin E recommended, to condition the area and heal the burn/darker area now that I've discontinued using the hydroquinone 4% product?
