Our reaction to these masks was, "YAAAAAS!" While they were on, they felt cooling, refreshing, & relaxing. The instructed 30 minutes passed too fast! After we took them off, the effects were immediately visible — our cheeks were lifted, taut, & plump. We masked in the evening which we recommend since we woke up with glowing skin. Two thumbs up Dr. Jart, we'll absolutely use these again!
