I had mild to moderate acne for about 3 years, and have just recently succeeded in clearing it completely using benzoyl peroxide creams. I have many red/pink marks (no scars) left all over my face that I really want to get rid of. I understand it takes some time for a mark to heal, but some of these must be a year old or more because there are just so many. I have tried using hydroquinone and AHA cream for several months without noticeable results, and most recently I used hydrocortisone for 5 days to see if maybe the marks are post inflammatory erythema instead of PIH, as I originally thought. I haven t seen much change though, and I know I can t continue with hydrocortisone for more than a day or two more. What do you suggest to help these spots heal?
