First popularised in Korea and Japan, sheet masks are portable, easy to use and make everyone on the planet look terrifying (in a good way). More than a fad, they’re the skincare equivalent of eight glasses of water, since your skin bathes in serum for a nice chunk of time (many stand-alone serums evaporate after application, says Charlotte Cho, co-founder of Korean beauty site Soko Glam). Dermatologist Dr Jessica Weiser also likes them as a quick fix, to deliver “a ton of moisture and anti-ageing ingredients in one step”.
RETHINK THEM IF
You can’t stand the slime or cold feel. If that doesn’t appeal, stick to cream masks.
