COSRX Snail Mucin Essence

COSRX Advanced Snail 96 Mucin Power Essence

코스알엑스 달팽이 에센스 · 코스알엑스 어드밴스드 스네일 96 뮤신 파워 에센스

A lightweight 96% snail-mucin essence that layers in hydration and helps a stressed barrier settle — without a heavy or greasy finish.

96% 달팽이 뮤신을 담아 수분을 겹겹이 채우고 지친 장벽을 가라앉히는 가벼운 에센스 — 무겁거나 번들거리지 않는 마무리.

Best for: Dehydrated, sensitive, or post-blemish skin that wants hydration and recovery in one lightweight step.

Not for: Anyone with a known allergy to snail-derived ingredients, or people who dislike a slightly slippery, tacky essence texture.

이런 사람에게: 수분과 진정을 가벼운 한 단계로 원하는 건조·민감·트러블 진정기 피부.

이런 사람에겐 비추: 달팽이 유래 성분에 알레르기가 있거나, 약간 미끈하고 쫀득한 에센스 제형을 싫어하는 사람.

What people say [4][6]

Pros and cons below are recurring themes across major retailer reviews (Olive Young Korea, Olive Young Global). Exact review counts sit behind dynamic widgets and were not captured — marked accordingly.

아래 장단점은 주요 리테일러 리뷰(올리브영 국내·글로벌)에서 반복적으로 나타나는 내용이다. 정확한 리뷰 수는 동적 위젯 뒤에 있어 확보하지 못해 그렇게 표시했다.

Pros

  • Noticeable plumping and hydration for most skin types
  • Often calms redness and post-acne irritation
  • Layers cleanly under toner, serum, and moisturizer
  • 대부분 피부 타입에서 뚜렷한 수분·볼륨감
  • 홍조와 여드름 자국 진정 경험이 많음
  • 토너·세럼·수분크림 사이에 깔끔하게 레이어링

Cons

  • Slippery, slightly tacky feel that some people dislike
  • Snail sourcing is a dealbreaker for vegan or ethics-focused users
  • Occasional stringy bits of filtrate from the pump
  • 미끈하고 약간 쫀득한 사용감을 싫어하는 사람도 있음
  • 비건·윤리 기준 사용자에겐 달팽이 원료 자체가 배제 요인
  • 펌프에서 가끔 실처럼 엉긴 여과물이 나옴

Good to know

Snail-derived, so patch-test if you have known allergies. It is fragrance-free, but still introduce it on its own so you can read your skin's response.

달팽이 유래 성분이므로 알레르기가 있다면 패치 테스트를 권한다. 무향이지만, 새 제품은 하나씩 도입해 반응을 살피는 것이 좋다.

Brand claim: COSRX markets 96% snail mucin for hydration and barrier strength, and states the essence is hypoallergenic, "proven by 68 days of testing with 87 participants."

브랜드 주장: 코스알엑스는 96% 달팽이 뮤신으로 수분·장벽 강화를 내세우며, "87명 대상 68일 시험"을 근거로 저자극(hypoallergenic)이라고 표시한다.

Independent test data: Beyond the brand's own participant test, no independent third-party clinical data was confirmed at build time.

Where to buy

Global: Amazon, YesStyle, Olive Young Global
