There's been much talk of the hour-long, twelve-step skincare routine that Korean women reportedly indulge in twice a day to keep their complexion looking its best, but, seriously, who has time for that?
Sheet masks, on the other hand, are a Korean invention we can totally get behind.
Unlike traditional masks that you spread on then wash off, with a sheet mask, all the skin-soothing goodness is saturated in a face-shaped sheet that you place on cleansed skin, then peel off when it's done.
They do look slightly scary, like some kind of a post-cosmetic surgery bandage, but the effects are well worth 15 minutes of weirdness - plus they make for a good Instagram post.
Here are our top 10 sheet mask marvels...
1. The perfect shot
"I've always been impressed by how good Korean women are at listening to their skin," says Katalin Berenyi, co-founder of Erborian.
"This inspired me to create 'shots' of serum for the skin - travel-friendly, take-anywhere masks that promise instant beauty results for all women."
The Erborian Bamboo Shot Mask, £6 each, enriched with Bamboo Waterlock complex, is designed to create the 'tchok tchok' plumping effect that Korean women covet.
2. The luxury lifter
The mack daddy of all sheet masks, Givenchy Le Soir Noir Face Mask, £225 for four, Debenhams, is a black lace beauty inspired by the Riccardo Tisci's catwalk designs.
Pressing a reservoir on the packet releases Vital Black Algae Sap Concentrate, a powerful serum that works with the lace to lift and resculpture where you need it most.
3. The beauty-foil booster
A world first, the Estee Lauder Advanced Night Repair Concentrated Recovery Powerfoil Mask, £16 each, is a foil-backed sheet that allows the hyaluronic acid-rich serum to penetrate deeply and deliver maximum moisture in just 10 minutes.
4. The waterless wonder
New at Selfridges, Nannette de Gaspe's Restorative Techstile masks are unique because they're dry - the lifting properties of the Neck Masque, £70, are woven into the fabric and are activated by massaging. Plus, they can be reused about five times.
5. The cutesy cooler
Forget what it does to your skin (which is moisturise marvellously with soybean extract, mushroom extract and witch hazel), this Pretty Animalz by Look Beauty mask is one seriously adorable skincare treat that makes you look like a tiger when you wear it. Snap it, story it, it's cute.
6. The marine miracle
Starskin Detoxing Sea Kelp Leaf Face Mask, £12.50 each, ASOS, is a two-part mask that's cut from sustainably sourced Korean sea kelp and with a whole bottle's worth of organic serum added, bringing 72 hours of hydration and wrinkle-smoothing marine goodness.
7. The next gen hero
Formulated to give skin a wake-up call, Maskorea's Too Many Light Night's Sheet Mask is enriched with Vitamin C to pep up tired or dehydrated skin.
8. The triple threat
Combining antioxidant-rich raspberry, soothing rosehip and collagen-boosting Tamanu oil, Origins Plantscription Youth-Renewing Sheet Mask, £32 for 6, John Lewis, soaks skin with a trio of anti-ageing actives.
9. The radiance renewer
Bringing the expertise of the Splendieuse range to an intense weekly treatment, Nuxe Splendieuse Anti-Dark Spot Perfecting Mask, £30 for 6, Escentual, supplies your skin with an amplified dose of the patent-pending, dark spot-defeating serum/
10. The spot corrector
If you're prone to acne, drenching your skin in serum might exacerbate the problem, but Skin Republic Spots & Blemish Sheet Mask, £4.99 each, Superdrug, won't.
Instead, tea tree and salicylic acid get to work on reducing oil, clearing pores and calming existing blemishes.
