1 week ago I had treatment with the alexandrite laser for freckles across my cheeks after carrying out a successful patch test before. The treated freckles turned dark brown and fell off on days 3/4. I went back yesterday to have treatment for the nose and chin. The dr. informed me that they would use the ruby laser. Today the spots look like burns and are raised like pimples.The spots are a reddish brown colour and have not gone dark brown. Is this usual and what steps should I be taking?
