For acne scarring you probably need a more aggresive treatment regimen than something you can get at home. I have seen a number of these cases and the results that can be achieved in a MediSpa environment are great. I also know a number of people who were dissapointed with the Home Tx regimens.
I suggest you go to a good spa and get the micro treatment done. Those drug stores machines are not as powerful as the spa quality machines. I get micro once a season to maintain my smooth skin, and I have baby soft skin, with a few pimples here and there but I am into maintainance when it comes to my skin. Don’t go cheap on your skin, the older you get the harder it is to restore it. I am 26 and noticing that my acne scars heal slower now. Good Luck!
PS- Check out DermNew if you want a at home treatment. I just got it as a gift and its decent. Still doesnt compare to at the spa but it can work in between your appointments.
