From India and dark skinned. I had melasma. The doctor recommended revlite laser for 20 sittings at 5 day interval in Jan'10. After which, my skin has hypopigmentation & have white spots all over my face. I keep applying sun screen regularly and I see good improvement. Certain areas turn from white to pink and gradually fade away.However there are still spots which don't seem to improve.Do the "not improved" spots fade away over time? Are these permanent? Is there any treatment I could go for?
