Another vote here for not going the E-Bay route. Have you considered laser? Yes it would be more expensive but it might do a better job against acne scars. And it's possible that in the end the cost difference might not be that significant when you factor in the number of treatments needed and the amount of downtime each type of treatment requires. I would at least look into any and all options first and include laser skin resurfacing
- but leave out the homemade one. Best of luck.
