The COSRX Advanced Snail 96 Mucin Power Essence, a viral K-beauty serum, has been praised for its firming and glow-inducing results. Now available at £11.40 during Amazon's Prime Day sale, down from £23.99, the product has gained cult status among beauty enthusiasts seeking flawless skin.
What Makes the Serum Special?
Formulated with 96.3 percent Snail Secretion Filtrate, the serum claims to maintain skin hydration while combating dark spots and signs of ageing such as fine lines and wrinkles. The snail mucin contains glycolic acid, glycoprotein enzymes, and copper peptides—ingredients typically found in high-end products. Other brands also offer snail mucin products, such as the Beauty of Joseon Revive Serum Ginseng + Snail Mucin (£11.25 from LookFantastic) and Byoma's Phyto-Mucin Glow Serum (£15 from Cult Beauty).
Our Writer's Seven-Month Test
Trends Writer Lucy Farrell tested the serum daily for seven months. Initially, after four months, she was not convinced—finding it slightly drying and not seeing the 'glass skin' effect. However, after seven months, her opinion changed. 'My skin now looks brighter, smoother and more even-toned, and it's become a product I don't want to be without,' she said.
Farrell made two key adjustments: applying the serum to damp skin immediately after cleansing, and using it twice daily instead of once. These changes helped lock in moisture and improved results significantly. She noted that the tacky texture absorbs quickly and does not leave skin sticky.
Final Verdict
Farrell concluded that patience and consistency are crucial. 'The age-old saying 'good things come to those who wait' applies to skincare,' she said. After consistent use, her skin maintains a lasting radiance without appearing oily, and her complexion has become more even. She emphasised that users should not expect overnight results and must apply the serum regularly to see genuine improvements.
