Others say it’s a “game changer” for aging complexions.
In 2024, I got more compliments on my complexion than ever before. While I test hundreds of skin care formulas for a living, I credit my newfound glow to the viral Cosrx Snail Mucin Essence. (Just ask my friends, I can’t stop raving.) Since I’m such a fan of the K-beauty brand, I’m refreshing my 2025 regimen with its other popular formulas. Notably, I’m snagging the Peptide Skin Booster Serum, which happens to be a whopping 55 percent off thanks to an on-site coupon.
The now-$11 product contains a treasure trove of skin care heroes, including hyaluronic acid to deeply hydrate, plus niacinamide and six peptides to plump and smooth fine lines and wrinkles. To experience its benefits, apply the lightweight serum as the first step in your regimen after cleansing. Thanks to its soothing feel and gentle-yet-effacious ingredients, the product is safe for all skin types.

I’m not the only one eyeing the Cosrx Skin Booster Serum; more than 20,000 people purchased the skin care gem in the past month alone, according to Amazon. One reviewer raved that they “looked 15 years younger” after using the serum for a month, adding that their skin “feels tightened and moisturized,” plus their “radiance is out of this world.” The same person went on to crown the product a “game changer.”

Fans of all ages and skin types swear by the budget-friendly pick. A customer in their 60s with combination, blemish-prone skin saw “almost instantaneous results” with the serum; it “firmed,” made their “pores appear smaller,” and delivered “such a healthy glow.” Another shopper confirmed that the serum left them with a “more radiant and youthful” complexion, making their skin “noticeably smoother, plumper, and more hydrated” after just one application.
