This woman's wrinkling around the mouth is about the mildest that I would consider appropriate for a peel.  Any less wrinkling, and I'd ask her to wait.  She was a good candidate from the standpoint of skin color: her pale skin was at low risk for a noticeable change in pigmentation resulting from the peel.

Our target was correction of the wrinkles in the upper and lower lips, and the more prominent wrinkles that looked like parentheses around the corners of her mouth.
