Try: Sulwhasoo Snowise Ex Brightening Mask, $130

Each disposable sheet mask is infused with white ginseng and individually fermented for two weeks for some serious brightening that seeps deep into the skin.

"Fermented skin care products are the most natural and traditional way to restore 'good' bacteria to the skin to reduce inflammation because they are much more easily and efficiently absorbed into the skin," says Hilary Burns-LaRiche, education and marketing manager at Sulwhasoo. (By contrast, probiotics that are eaten have to make it past stomach acid alive to have any benefit.)

Try: Fresh Black Tea Instant Perfecting Mask, $88

The black tea in this firming mask isn't the usual stuff you brew. It's a ferment (aka kombucha) that's loaded with antioxidants. According to Fresh co-founder Lev Glazman, the elixir reenergizes the skin's cells. This moisturizing cocktail also features other skin-improving (and refreshing-sounding) ingredients, including lychee seed extract to support natural collagen and jicama root juice for extra hydration. Translation: it plumps up skin and helps prevent sagging.
