How can i convince my mother to let me undergo an acne scarring treatment?

Physician's help: Parents often have curious superstitions about acne and interfere with needed treatment -- even young people nowadays get scarring that will be a liability for a lifetime. You won't be able to persuade her, but if this is an indicated procedure, a competent physician may be able to. If your primary care doctor can't help, cajole a dermatology consult.
