I had a friend who had this done only a week ago, I have not seen her since as she is still in hiding! Not sure if it was that exact some procedure but it cost her 7K. I offered to do it for here for free but Nooooo she wanted to part with some $$$$. They do say that beauty is only skin deep but ugliness goes right to the bone!
Looks to me like this is actually a legitimate treatment for acne scaring. It does sound expensive, but so are most elective surgeries. A medical CO2 laser is going to be several magnitudes more pricey than the chinese things we're familiar with.
