I am 23 and have ice pick and light purple spot acne scarring. Peels, IPL, and pro-fractional have helped some but only temporarily and I have not received the more permanent result I want. I have an appointment booked with my doctor for the total FX and I want to get the best result possible. He said that I should do anywhere between 10 and 30% for the deep FX portion. I have read that with more aggressive treatments there is a bigger risk for hyper pigmentation. Would 30% be too aggressive?
