It’s been a few years since Korean skin care first landed on our radars (also known as our Twitter and Instagram feeds), but the beauty world’s collective fascination for all things K-beauty shows no signs of slowing down. Korean skin care is known for its groundbreaking formulations, surprising ingredients and flatlay-ready packaging. It got us obsessed with sheet masks, introduced us to bee venom and snail mucin and even prompted us to google words like “chok-chok,” “ampoule” and “essence.” And thanks to makeup artist Ellie Choi’s now-viral skin care routine—and accompanying selfie showcasing her impeccably smooth, translucent skin—another term has been added to the ever-expanding K-beauty lexicon: glass skin.
What Is Glass Skin?
“Glass skin is a term for exceptionally smooth, even-toned and lustrous skin that’s so flawless it has the appearance of glass,” says skin care blogger and K-beauty expert Jude Chao. “It’s simply a clear and elegant way of describing a certain type of enviable complexion,” she adds. Like its predecessors “honey” and “dewy” skin, glass skin aims for an intensely moisturized skin that gives off an almost transparent complexion and a “very youthful, lit-from-within glow,” adds K-beauty and skin care blogger Sheryll Donerson.
The Glass Skin Regimen
While some skin care trends are focused on particular products that promise instant visible results, achieving glass skin requires a multi-dimensional approach, says Chao. “The surface of the skin must be extremely smooth, without bumps or rough texture. Directly beneath the surface, there should be a large amount of water in order to create the moist and lustrous appearance that catches and reflects light. Finally, the skin should look plump and firm,” Chao explains.
Achieving this coveted dream-like visage requires “a consistent skin care routine consisting of a cleanser, toner, serum, exfoliator and a hydrating moisturizer,” says Donerson. And because intense hydration lies at the core of a glass skin regimen, Chao recommends opting for “watery products with humectants like hyaluronic acid and glycerin and considering using either multiple layers of one hydrating product or several layers of different ones,” she explains. K-beauty staples like toners, essences and sheet masks are the most effective hydrators, according to Chao.
Below is a step-by-step guide on how to achieve clear, glowing, glass-like skin.
Step 1: Double cleanse
Asian skin care introduced us to double cleansing, and we haven’t looked back since. A clean canvas is a must when it comes to your skin care routine, especially at night when your face has collected all that dirt, grease and makeup residue. Start with a cleansing oil or micellar water for your first cleanse, then follow with a gentle foam wash or cream cleanser.
Step 2: Exfoliate
We can’t talk clear and smooth skin without mentioning exfoliation. “Whether using a physical exfoliator (such as crushed walnut or gentle jojoba beads) or a chemical type (like glycolic or lactic acid), this step will slough away dead skin cells that dull skin and clog pores,” says beauty chemist and skin care expert David Pollock, founder of JustAskDavid.com. Don’t overdo it, though. Two to three times weekly is ideal to avoid irritations, especially if you have sensitive skin.
Step 3: Tone
Traditional toners are often ignored because some find them to be too drying, but in Korean skin care, they take on an entirely different role. K-beauty toners are formulated with refreshing and moisture-enhancing ingredients (like green tea, galactomyces, ginseng and floral water) and are applied not only to restore the skin’s pH levels but also to provide base hydration and allow better absorption of oncoming products. “Layering is key here to achieving the extremely hydrated skin that’s necessary for glass skin, so the 7 Skin Method—applying up to seven layers of toner to your skin—in general, works well for this,” explains Chao.
Step 4: Add an essence
Essences, the less-concentrated relatives of serums, tend to be more lightweight and watery in consistency (a cross between serums and toners). Like targeted treatments, they’re formulated to address skin concerns like pigmentation and redness but with the added purpose of delivering mega moisture and hydration.
Step 5: Treat with a serum or ampoule
The Korean counterpart of serums, ampoules typically contain a higher concentration of multitasking active ingredients. “[These] concentrated actives help nourish the skin, reverse signs of aging and promote collagen to help provide firmness, minimize pores and even out skin tone,” explains Pollock. Some ampoules are only meant to be used over a certain period of time (to target skin emergencies), so for daily use, switch to a hydrating serum with moisture-boosting ingredients like hyaluronic acid, ceramides and vitamin E. “For structural firmness, vitamin C and retinoids will encourage collagen production most effectively,” adds Chao.
Step 8: Seal with a Mask
K-beauty has given us some of the best skin care tips and tricks, but masks are arguably the ones the beauty world is most obsessed with. They also happen to be the easiest way to soothe tired skin, repair damage and lock in and replenish moisture.
