I'd be shocked if you haven't seen this overnight sheet mask all over your FYP. Smooth it on your face and go to bed. When ya wake up to peel it off, it'll be clear (a sign that your skin's absorbed all the mask's goodie collagen, niacinamide, allantoin, and hyaluronic acid).

I picked this up in South Korea last month (brag), and I've used it every other night since religiously. It makes my skin feel as soft as buttah after I wake up and peel off the remnants of it, thanks to collagen, ceramides, and hyaluronic acid. Annoyed I didn't buy it at 32 percent off though...

I'm so annoyed I didn't wait to buy this on Cyber Monday since it's currently a whopping 50 percent off. But whatever, now I can tell you after testing it how fab it is for calming down angry, aggravated zits, thanks to niacinamide, centella asiatica, and allantoin.

When I went to Korea with a group of beauty editors, everyone flocked to the Beauty of Joseon section of the store in search of this beloved sunscreen. It blends in so easily with zero white cast—a strong feat for an SPF 50 with UVA and UVB protection.

Most cushion foundations, although so glowy and stunn, only come in a few shades. Womp. But not this TirTir one, which actually has a variety of 40 (!!) shades—basically unheard of for a K-beauty foundation. When our editor Olivia Truffaut-Wong tested it, she said it felt hella lightweight while offering up a medium to full coverage.

When I've got red patches on my face, I just pat this in and it basically disappears. Magic, huh? (Sorta, it's a combo of the green tint and centella asiatica soothing the hell outta my skin.) This 30 percent off deal won't last, though.

FYI: Toner pads are the "it" thing in Korea rn, including these exfoliating ones from Needly that are on sale over Black Friday weekend. Wipe 'em all over your face, stick 'em on as makeshift sheet masks, or spot treat with 'em on your zits. The world is your oyster.

Cool thing about this formula (which was developed by Charlotte Cho, founder of K-beauty retailer Soko Glam): It's both hydrating and exfoliating.
