If you’ve binge-watched Single’s Inferno 4 (we totally did too!), you’ve probably wondered: How do the contestants look so effortlessly flawless? Spoiler alert: It's not just good genes or Netflix magic. 

From dewy "glass skin" to lips glossier than a Jeju sunset, Single’s Inferno 4 contestants have become walking billboards for Korea’s hottest beauty trends — and netizens are eating it up. 

We’ve decoded some of the most popular K-beauty products spotted on the contestant's vanities, from lip combos to cushion compacts that’ll have you serving looks so flawless they’d make even Netflix’s 4K cameras blush.

The Cushion That Dethroned Foundation: Jungsaemmool Essential Skin Nuder Cushion

Used by four contestants (including sportscaster Kim Min-seol and model-turned-It-girl Lee Si-an), this Jungsaemmool cushion is the secret behind their "I woke up like this" glow. Its micro-fine pigments blur pores and redness while mimicking skin’s natural texture — no cakey finish in sight.

But the magic lies in its "hue-balancing tech," a proprietary innovation that neutralises discoloration and evens out skin tone, whether you’re battling sunspots or post-bonfire blush. 

Infused with hydrating heroes like hyaluronic acid, the lightweight formula doubles as skincare, locking in moisture for a dewy radiance that aligns perfectly with Korea’s obsession with glass skin.

Why everyone’s obsessed: It’s the brainchild of Jung Saem Mool, celebrity makeup artist to K-drama royalty like Son Ye-jin. Bonus: Refillable compacts are eco-friendly catnip for Gen Z.

Jungsaemmool Essential Skin Nuder Cushion is available for $26.50 (set of cushion compact and refill) on Lazada.

Pro tip: Complete your eye look with the Heroine Make Long Up Mascara Super Waterproof (another cast favourite) for monsoon-proof lashes.

Contour Like A Pro

If there’s one K-beauty step Koreans treat as non-negotiable, it’s contouring. Forget heavy bronzers — Seoul’s approach is all about subtle shadows that mimic natural bone structure. 

Nowhere is this more evident than on Single’s Inferno 4, where Si-an’s razor-sharp jawline and perfectly sculpted nose owe their drama to two iconic products: Etude House Contour Powder and Too Cool for School

Unlike Western bronzers that lean orange, the Etude House Contour Powder has a grey-beige undertone that subtly chisels cheeks, temples, and jawlines without screaming “makeup.”

So why is this contour powder beloved in Korea? For starters, it neutralises redness and creates depth on East Asian skin tones, making it a perfect match for many. The sheer, buildable formula is forgiving for beginners; a light swipe provides a hint of definition, while layering allows for more dramatic contouring when desired.

The best part is its skin-like finish. The powder blends seamlessly into the skin, avoiding the dreaded “muddy” look that can occur with other products.

Etude House Contour Powder is available for $18 on Lazada and $36.72 on Olive Young.

Too Cool for School Art Class by Rodin

This three-colour face palette is so ubiquitous in Korea that even the contestants had to label it with their names. 

Featuring three shades — warm taupe for bronzing, cool grey-brown for contouring, and neutral beige for blending — they work together to create dimension and definition that looks like you were born with it.

But it's not just about looks. This palette is a skincare champion too, formulated without parabens or mineral oil to keep even sensitive skin happy.

Too Cool for School Art Class by Rodin is available for $26.03 on Amazon.
