Whether you're looking to fade dark spots with regular use, or need a one-time brightening treatment, Garnier Skin Renew Dark Spot Treatment Mask, $2.83 per sheet, will do the trick. The tissue-thin sheet mask is doused in hydrating ingredients and vitamin C for brightening.

This sheet mask from Hada Labo Tokyo, $3.75 per sheet, contains hyaluronic acid and marine-based collagen to smooth out wrinkles and firm skin while hydrating.

During Fashion Week, the models backstage at Richard Chai were pampered with Dr. Jart+ sheet masks -- they're great pre-makeup. While there are a number of different formulas available, we like the Pore Minimalist Mask, $7.50 per sheet, which contains detoxifying ingredients like Korean charcoal to draw out all the gunk that clogs your pores.

DHC Alpha-Arbutin White Mask, $4.50 per sheet, does a little of everything. It contains mulberry, serine and peony extracts to moisturize, and alpha-arbutin to brighten skin. And it even has flaps that sit on your eyes to gently treat wrinkles.

Whamisa Organic Sea Kelp Facial Sheet Mask, $14 per sheet (available on Korean import site Glowrecipe.com), is exactly the kind of weird-looking beauty treatment that gets us going. Made entirely of sticky green sea kelp, it feels as strange as it looks, but once you take it off, you'll have a dewy glow that lasts for days.
