I've never been a big mask wearer. I just don't find the time or have the patience to sit and plaster some mud on my face. I was given the Aceology Probiotic mask as a sample. I was hesitant at the long leave on time of 30 minutes and wasn't too hopeful it would be any different from other masks I tried in the past. When I opened the pouch, I was surprised to see the face mask all ready to go. I assumed it was just some gooey stuff to slather on my face. I put it on, put on the timer, and went about my daily chores. When I removed it, my face was so much healthier looking. It felt nourished, moisturized and even had a nice glow. I have sensitive skin and suffer from redness. This mask really toned it down and helped my skin look less inflamed. I was pleasantly surprised and I've been converted to doing masks, well done Aceology! They seem a bit pricey, but for the quality and results, I'm willing to splurge on them once in awhile.
