I got a lot of these masks back when they were on sale. The ones I purchased were Pomegranate, Bamboo, Lemon, Coenzyme Q10, Aloe and Silk Cocoon (Hyaluronic Acid in the picture was a free sample). I love the Etude House masks because they're pretty cheap, moisturizes, and actually fits my face very well! A lot of the sheet masks I've used in the past were too large, but these masks are cut just right. Each "flavor" is supposed to do something different, and the claims are written on the package in English--e.g., Pomegranate is "Smooth & Energizing" while Coenzyme Q10 is "Tightening & Firming". I'm not sure if each one does something different, but after using the mask, my skin is definitely smoother, more moisturized, and feels "plump". The other thing I've noticed is that Silk Cocoon has a white cream-type serum (all the other masks have the standard clear-type formula that you find in most sheet masks) so that was a bit weird, but still works. I would recommend and repurchase!
