I love this stuff and have been buying for years! Have tried many more expensive, newer products, but always return to this for a quick skin pick me up. I use a lot of strong products on my face, prescription and otherwise, and sometimes develop flaky or dry skin. I apply this mask in the shower and remove with a Clarisonic or washcloth and emerge with truly glowing, clear skin. Will this mask get rid of more serious issues like melasma or sun damage? Probably not. I go for professional grade chemical peels for that kind of issue. But for a beautiful skin brightening-up that makes makeup go on flawlessly and gets rid of any kind of dullness? Love it and it will forever hold a place in my routine. I have tried multiple enzyme peels from other, generally more expensive brands (Juice Beauty, Andalou Organics, Peter Thomas Roth, Z. Bigatti, Ren, etc) and just keep coming back to this one.
