Very happy with VI peel on face, but not so much on neck

I had great results with a medium depth VI peel on my face. I asked my provide to put the solution on my neck as I have wrinkles and sagging that I hoped to improve. She told the me neck skin was thinner, so she could not put as much on. I wish she had talked me out of putting any on! The skin on my neck became very sensitized. It has been a year, and it still gets red and irrirated more easily than before. The texture is also off. I would recommend this procedure, in fact I had 3 last year. I would just advise everyone to avoid your neck.
