First I want to say thank you for your business! Now to answer your question...Everyone skin is different and because of that results may vary from person to person. You can expect the texture of the skin to start improving within the first few weeks. Skin tone should start evening out after about a month. Collagen and elastin improvement will begin after your first two to three months. Small scar reduction takes around six months to a year.
Every human body improves at a different rate so have patience with yourself and the results will come! The good thing about glycolic acid is you will always keep improving over a period of time.
