Is PIH Following Fraxel Repair Permanent?
I am being treated with 4% hydroquinone for the past 4 months for post-inflammatory hyperpigmentation (PIH) following Fraxel Repair. The hydroquinone does not seem to be working. Is PIH permanent? If not, will it eventually disappear on its own? Furthermore, if it ever gets resolved, is there a chance that it may come back?
