I don t understand what is happening and i m vry depressed .Please help ,
Hi, usually 10% glycolic acid does not cause PIN, but still feel then stop the treatment. I would suggest.you stop applying all this treatment for now, let the lesion appear.it seems that either because of medicine you're applying had some sort of photo reaction.which is responsible for redness.decrease the dose or frequency with better sun protection.
