Alternating Glycolic Acid & TCA Peels

Hi, I want to alternate between glycolic acid peels 50% and TCA peels 12%. I usually have to do at least 3layers of GA peel to feel the sting, and even that I never had any peeling/flaking afterward.I also did tca peels 12% with 3 layers and this gave me better result with light peeling.Is it safe to do aha peel once/week, & do tca peel at the 4th week mark? I'm Asian with brown spots from past acne, with fine wrinkles.I just want to make sure I do not overkill my skin by this method.Thank you!
