I love love love this mask! It's exceptionally hydrating (especially after an at-home facial, complete with microwave steam towels)! I typically leave a thin layer on overnight under my heavier night cream. When you wake up, your skin is super soft and supple! Also, it's a great value. I've only ever purchased the 1 oz mask in sample packs, and it lasted me at least 5 full masks, plus wearing it under my moisturizer several times. So go for the big one, it will last forever! Oh and p.s. keep it in the fridge for a refreshing, soothing, and cooling experience.
