Glycolic acid is pretty light, so it would take a while to get rid of even shallow scars. You should try something like BHA acids, while would help more. For more immediate results, you should look into getting some stronger peels done at a dermatologist office (not as bad as you might think). You can definitely get rid of light scars with chemical peels.
oh ok thanks ! is there any kinds of scars that peels cant get rid of ??? also i read some where that if you use a AHA cream for like 8 months , it is the equivalent of a deep peel. i dont know if that was just becasue they were advertising cream... ??? thanks !
