I am a light skin Asian and using 50 % glycolic peel at home. I have done 4 peels already. How much longer till I see fading in the spots? I feel like the spots are getting darker and more are forming. Please, advise. I have gotten peels done professionally and started with the 30% glycolic peel before upgrading to the 50% glycolic. But it don't seem like the peels are working but getting worst.
