After I had bad breakouts as teenager (circa 1995). I was left with a lot of deep acne scars and hyper pigmentations. My doctor decided to put me through a series of Iontophoresis Treatment (once a week). For about 1 year. I saw big improvement in every way. My skin was smooth, bright and clear. I didn't have any more hyper pigmentation or indentation. I'm very thankful for it. I don't see any place offer this treatment anymore. I'm not sure if it's because it require several treatments. Or it's an old technology. But it worked well and has no side effect. I think it's better than laser in my opinion.
Iontophoresis is a process using a low electrical current to create ion field to drive vitamins or medication through the skin surface. Each treatment lasts about 30 mins and it's painless.
