I did my second peel, which I have not completely recovered from- I used a 25% solution. I haven't noticed much difference at all in my fine lines. Does it take many peels to notice a difference? I'll tell you this: I will NEVER do a full face 25% peel again. OUUUUUCH! The tightness drove me BATTY and I finally peeled and it was such a relief. I will only do parts of my face from now on. Wow. It was so much tighter and uncomfortable post-peel than the 4 layers of 12.5% even. It itched and was so tight it was UNBELIEVABLE. I did it a week ago and my face is still red in some places and "re-flaking." Man oh man. Somebody was right when they said that when you heal from a peel and say WOO HOO I'm ready for another peel is akin to giving birth. You FORGET the pain!! LOL Applying it was not the *problem*. It was the extreme tightness and waaaaaiiiiting to peel. OMG I wanted to peel the skin myself to get some relief!! My face is still a tad swollen in areas- not bad at all, but I can tell. I just don't want to keep doing peels if they aren't going to improve my fine lines. My skin is even and I don't have age spots. Is it worth it??
