I started getting VI Peels in Oct 2010 and have gotten about 6 from Oct 2010 to Dec 2011. Love them. I get them on Thurs, put makeup on on Friday and go to work. I plan to stay home all weekend to peel and am fine to go back to work on Monday. I have very oily skin, so the dryness after peeling is a blessing for a few weeks. Acne is much better and old scars are reduced, not perfect, but better than anything else I have tried with out uses lasers. If you have new acne and scars you will need to get more peels to address the new issues.
I really think your experience all depends on who you have do it. My Nurse Practicioner told me what to expect and she was 100% accurate. No surprises or exagerated results. She told me I would need to get multi peels to get the results I wanted. PS: I do have very sensitive skin and could not use some of the harsher lotions and bleaches on my face, but had no issues with the VI Peel.
