I had laser hair removal professionally done. During the pandemic, I had purchased an at home laser for the few pesky hairs that I was still trying to get rid of. About 1 year ago, the laser accidentally slipped out of my grip & I burned the outside of my labia. I didn't notice until showering, that the area had turned completely white. The skin has healed but remains white. It is mostly smooth but also slightly rough. Is there anything I can do to help with the discoloration.
