Is 30% Glycolic Acid Safe to Use on a Weekly Basis on Mixed Race Skin?

Depending on the PH and free acid content of the 30% glycolic acid peel, weekly treatments may be excessive depending on your skin's reaction to the peel.   If there is not redness, peeling or inflammation following the peel, it may be OK to have it done every week.  If the skin is red and peels after each treatment, weekly applications are probably too frequent.

30% Glycolic Acid should only be used by a professional and not to be used on a weekly basis.  Using it on a weekly basis could do more harm than good. Your skin could become red, irritated and peel. This is something I would think you do not want on a weekly basis. Look for a licensed aesthetician in your area to assist you with your acne spots, scars, and oily skin.

I would be cautious! Is this a professional product? It really depends on the ph of the acid. I would only leave it on 30 seconds then, neutralize with water. If your skin responds well, you can leave it on longer the next time. Gycolic acid is a great exfoliator, but weekly treatments may be excessive. Over time, this will decrease pigment spots from acne. A deeper peel would help improve acne scars.

Glycolic acid is superficial peel, it will NOT affect pores, acne scars or oily skin.

Light or superficial chemical peels using glycolic acid penetrate to the bottom layer of the epidermis and will stimulate growth of a new epidermis. They are better suited for mild to moderate textural imperfections, fine lines, pigmentation irregularities, and acne lesions. They may also be helpful for pores and oily skin but do little for acne scars. They are designed to be repeated weekly or every other week because of their quick re-epithelialization times. There is little discomfort, minimal down-time, and gives reasonable results. There is no "cook book" approach to application times as this will depend on many individual factors.
