Hello, for a year I've been using Philips Lumea 9000 Prestige for hair removal. I am caucasian, blonde hair (but dark hairs in specific areas). I have noticed some sort of dissappearance of my dark spots on the treated areas. Is it possible that the IPL device did this? Can I actually use this Lumea 9000 Prestige for treating dark spots, birth marks, scars and so on? How do I know which device can do that? And can I find the proper home procedure steps to work on this? Thank you!
