In my opinion I would say that the best thing I have come across so far is micro-needling, I have used many products and creams to get rid of acne scars and this has come out on top of them all.
Micro-needling of the skin is an increasingly common cosmetic procedure, but the Scientia Derma Roller is an FDA approved application which is simple enough that you can perform it yourself at home. In fact, it has similar results to Laser Treatment, Chemical Peels and Dermabrasion, but it is considerably less invasive and carries only a fraction of the cost.
have a look on http://www.derma-rollers.com and see what you think.
good luck.
