A very good exfoliant I discovered a few years ago in my institute and it is the only exfolient that is efficient on my skin: I have a sensitive and fine skin except on the chin where my skin is thick. Multivitamin Thermofoliant allows me to make my skin thinner on the chin (I've used so many exfoliants that were useless!) and I use it on the rest of the face as well, rubbing gently. I use it once a week.
