I am amazed by this mask! I used last night for the first time and am seeing smoother skin this morning! I've used a few other masks, to include a very expensive one that promises immediate results, but none of them compare to what I am seeing this morning! I subscribed to receive these on an ongoing basis and am so glad I did.

Worked great for my skin

First time I used this face mask was after a 10 minute Vitamin C 'peel' and application of 1.5%glycolic acid (with a facial pad). Left it on for about 45 minutes at which point the mask felt 'dry'. My skin felt so soft afterwards- it literally absorbed all of the moisturizing elements. Easy to apply and stayed put until removed. Highly recommend!

Effective and easy to apply

Been using for a a month and really like the way my skin feels as well as some of the blemishes that have gone away. Easy to take on a trip and easy to apply. Only downside is I wish it was for the entire face and not partial.
