My dermatologist recommended this peel and it is the best product I have ever used. I began using the entire actifirm line after seeing the results from this peel alone and my skin has never looked better. I used to have montly in-office peels but with daily use of the actifirm line I don't even need to do that anymore. I am an experienced skin-care user and have tried it all from prevage to skinCeuticals. This is the best kept secret out there.
