It seems Hye-jin's beauty stash holds the key — she owns a bottle of MISE-EN-SCÈNE Perfect Serum, an ultra-popular hair serum that's loved by many Korean celebrities for its hydrating and detangling properties. Get it on Shopee for $10.75.

Let's face it: some popular Korean beauty products simply won't fit deep skin tones, and there are loads of them, no thanks to the fair skin sported by many female celebrities.

Which is why we're paying even closer attention to Ji-yeon's makeup bag. As the only female cast member with noticeably tanned skin, her picks — like the rom&nd Better Than Eyes eyeshadow palette in Dry Buckwheat Flower — work better for girls with deeper skin tones. Get it on Shopee for $13.52.

Undeniably the it-girl of this season, beauty products used by Si-an on Single's Inferno have been blowing up nonstop on TikTok. The Round Lab Dokdo Toner Pads she uses are no exception, and we can see why. These pads are efficient and convenient to use, especially when you're travelling or on the go.

Bonus: these toner pads are infused with birch sap, which both hydrates and calms skin — perfect for sweltering weather, whether it's on Inferno, or here in our sunny and humid city! Get it on Shopee for $19.60.

Spotted on Haelin's dressing table, we reckon the Mediheal Hyalu Moist Essence Mask is one reason why her skin always looks flawless on camera. This sheet mask delivers hydration deep into the skin layer, keeping it moisturised and plump.

If you've got a little room to splurge, the Hair Ritual by Sisley's Precious Hair Care Oil is certainly worth checking out. It's at least partially responsible for Hye-jin's luscious locks, providing nutrition, radiance and softness to each strand without weighing it down.

It seems Si-an is a huge fan of Dasique's eye and cheek palettes, especially in one episode where she is seen sitting with four or five of them. Fans of the blushing beauty's style can opt for the Dasique Blending Mood Cheek palettes, which come in Candy Berry (Si-an's pick!) and Blueberry Sorbet. You can get it on Shopee for $20.93.

Steal A-rin's understated style with the ETUDE Contour Powder duo, a fuss-free contour palette that's perfect for sculpting your features. The palette captures the look of real shadows, giving your makeup a natural look, and comes in two variations: one for warm tones and the other for cool tones.
