The pink color of the skin is expected after an erbium laser resurfacing and will go away within a couple of months in most cases. If you have pigmentation, or a brown discoloration, that is most likely not going to go away quickly. It is very important that you protect your skin from the sun with a physical sun block that contains titanium and zinc. This should be applied several times during the day, every day. I'd recommend discussing your concerns with your physician. If your skin can tolerate it, I'd prescribe a cream with hydroquinone that you would apply daily. The cream can be irritating to some, and the irritation can make the pigmentation worse, so we don't want that to happen. Fortunately, the discolorations should eventually resolve, and the wrinkle reduction that an erbium laser can achieve is well worth the inconveniences you are experiencing.Andrew Campbell, M.D.Facial Plastic SpecialistQuintessa Aesthetic Centers
