I'm doing 4 treatments of fraxel and IPL. The first 2 treatments looked like this would be successful but spots came back even darker. 3rd treatment the same thing, spots darkened flaked off, had clear skin for a week then spots came back darker. I'm going in next week for my fourth treatment. I really don't think this is working but I don't know what to do? Spoke with the doctor who said I have low vitamin D. She perscribed me 50,000 vitamin D, 4weeks later no change to skin. Please help.
