I've used a few of the Montaigne Jeunesse masks and for the first few thought they were just okay. I didn't think it left my skin feeling that different than when I used a regular scrub face wash. They were inexpensive and the smell was nice, but overall noting amazing.

The last time I used one of the masks things really took a turn for the worse. I had a very bad allergic reaction - something that I've never had once in life. After a few minutes of the mask being on my face it felt hot so I washed it off sooner than directed (and I'm happy I did). All evening I could feel my skin tightening up and in the morning my face was completely swollen. As bad as it sounds, my one eye was even swollen shut. It took about two solid days before the swelling started to decrease. Since this mask I've never once had a reaction to any face product (ie. mask, cream, wash...)

My friends have used the same masks with no reactions, so perhaps it could be my skin type. My advice - buyer beware.
