I never had a Glycolic Peel but I have had two Beta-lift peels. (Supposedly this is what the celebrities get days before Award Nights to make their skin look "amazing").
This peel lifts dead skin off your face and stimulates new, young, and healthy cells to the surface. I really liked this peel a lot, yet I only have had 2. I've noticed some of my scarring has lessened, but not 100% I would need more peels for that. Unfortunately, my derm doesn't want me doing any peels as of now b/c I am on a strong medication. Yet I absolutely recommed the peel yet you will need more than one or a few treatments. It is a lunch time peel with no down time. You will peel about 2 days after the treatment. Also what I found amazing was that the day I got one of my peel treatments, I had burned myself with a curling iron above my eyebrow. It turned that nasty brown color (to scab and scar) yet 2 days after when I started to peel, it was magically gone!

No scab, and no scar!!
