I wanted to hate this mask because it's so pricey...but I can't. There's a reason it's gotten a lot of hype, and that's because it works. It's my go-to mask when my skin is acting up, and I've found that when I use it as a spot treatment, the admittedly tiny jar lasts me months.
One word of caution - this mask will dry up on you if you don't use it, especially once there's only a tiny bit of product in the jar. Always make sure the lid is on tight!
