What is more effective at clearing minor acne scars photo facial or the energy green peel?

Nothing specific: Numerous methods of resurfacing facial acne scars can work. Depending on how deep the scarring is different treatments may work better than others. In general facial resurfacing can be done with chemical peels, laser, or dermabrasion. Each of these has mnay variations. Some are minimally invasive and can be done in a spa or physicians office. Others go deeper and require anesthesia.

Neither!: Both of the listed options will do little to nothing except lighten your wallet, but the peel, depending on depth, will likely have the best of these two choices. If your acne scars are truly minor, then consider a "real" facial peel, dermabrasion (not microderm), or laser resurfacing. Unless you have a treatment that requires actual healing, there is bound to be little to no improvement at all!
