Korean skincare is often placed on a pedestal — and understably so. I’ve hardly tried an essence, snail mucin-spiked serum, or waterlight sunscreen from a K-beauty brand that’s disappointed me. This is particularly true for Cosrx. The ultra-popular skincare brand makes some seriously plumping formulas, many of which pave the way to glass skin. 

Conveniently, the brand is available to shop at Amazon, where it has thousands and thousands of five-star ratings. Better yet, a thrilling number of its offerings are on sale right now, including the best-selling snail mucin serum Emily Ratajkowski uses and its moisturizer counterpart that’s selling like hotcakes — seriously more than 100,000 people have bought it in the last month, per Amazon. My advice? Stock up while you can; these deals won’t last forever, but plump, poreless skin is always a good look.

Cosrx Snail Mucin ​​96% Power Repairing Essence

A best-seller at Amazon, this calming essence boasts over 43,000 five-star shopper reviews and ample acclaim, including from Emily Ratajkowski, who used the serum to calm her “freaked out” skin. True to its name, it contains snail secretion, an ingredient often found in skin-softening Korean beauty products thanks to its plumping powers. I’m a fan of the essence’s layerable formula, which plays well with other products in my routine and delivers an instant boost of smoothing hydration when my skin is particularly dry. 

Cosrx Snail Mucin 92% Moisturizer

A counterpart to the snail mucin essence, this moisturizer touts many of the same benefits, including long-lasting hydration and instant plumpness. In addition to its titular hero ingredient, the cream contains hydrating hyaluronic acid, line-lessening peptides, and a low dose of exfoliating glycolic acid to support supreme smoothness. One shopper says the cream helped them “obtain glass skin.” 

Cosrx Low pH Good Morning Gel Cleanser

This cleanser balances and maintains the skin’s pH levels for optimal clarity and smoothness. Spiked with beta hydroxy acid, it’s also ideal for mitigating overly oily pores — and, consequently, shrinking their appearance for a more glasslike look. Over 20,000 Amazon shoppers purchased this facewash in the past month alone. Furthermore, according to the brand, over eight million tubes have been sold worldwide.

Cosrx Niacinamide 15% Face Serum

ICYMI: Niacinamide, a form of vitamin B, is among the most versatile, universally-tolerated skincare ingredients, and has amassed ample acclaim from dermatologists. In addition to its calming, anti-inflammatory properties, niacinamide can whittle the appearance of large pores — and, in turn, bring you one step closer to the coveted, apparent poreless-ness for which glass skin is known. This serum contains an impressive 15 percent of the buzzy B vitamin, in addition to zinc — an excellent anti-inflammatory ingredient that also controls excess oil production, in turn lessening breakouts and further shrinking the appearance of pores. According to one reviewer, the serum significantly reduces midday shininess. 

Cosrx Honey Serum

Honey is more than a sweet treat. Topically, it’s antimicrobial, and can keep blemish-causing bacteria at bay. Honey is also a humectant, meaning it attracts, traps, and holds onto moisture from the environment, which in turn can plump the appearance of fine lines on contact. Finally, the vitamin-packed ingredient is a major glow-booster and can impart vibrance to dull skin almost instantly. This serum contains a heavy helping of its titular ingredient, and shoppers are impressed. The serum delivers a “natural dewy look” said one shopper, while another notes a “radiant glow” post-use.
