If the word peel scares you, don’t worry: I consider myself to have sensitive skin and I actually purchased the extra-strength by accident. It has never irritated and feels very refreshing. It is not the old-fashioned mask that you spread on and peel off...there is no real peeling involved. No red skin or flaking. I'm not sure others notice a difference, but I notice a reduction in fine lines and just a general improvement in skin tone. Then again, I have had a few compliments lately on my "general" appearance...maybe these peel treatments are why?
