I found a great deal at a highly revered local spa for a 99% glycolic facial peel recently. I have been eager to try a facial of this degree for some time now. I am young, but have some sun damage already from tanning a few years back (I now protect my skin dilligently), and also a few minor scars along my chin from old blemishes. Is this type of peel worth it? Or is it too abrasive? Can it correct the concerns I have, or should I skip it and try something more mild? Thanks!
