COSRX Low pH Good Morning Gel Cleanser
코스알엑스 굿모닝 클렌저 · 코스알엑스 로우 pH 굿모닝 젤 클렌저
A mildly acidic (low-pH) gel cleanser with tea tree oil and a mild BHA that rinses away overnight sebum without stripping — built as a gentle morning wash.
티트리 오일과 순한 BHA를 담은 약산성(로우 pH) 젤 클렌저 — 밤새 쌓인 피지를 당김 없이 씻어내는 가벼운 아침 세안용.
Best for: Normal, combination, or sensitive skin that wants a gentle low-pH morning cleanse that does not leave the skin tight.
Not for: Anyone needing to remove makeup or sunscreen (it is a light gel, not a makeup remover), or those who dislike any tea tree scent.
이런 사람에게: 당김 없이 순한 약산성 아침 세안을 원하는 보통·복합·민감 피부.
이런 사람에겐 비추: 메이크업·선크림을 지워야 하는 사람(가벼운 젤이라 클렌징 제품 아님)이나 티트리 향을 싫어하는 사람.

What people say [3][4]
Pros and cons reflect recurring themes across retailer reviews (Olive Young Global, Amazon); exact counts sit behind dynamic widgets and were not captured.
장단점은 주요 리테일러 리뷰(올리브영 글로벌·아마존)의 반복 주제이며, 정확한 리뷰 수는 동적 위젯 뒤에 있어 미확보.
Pros
- Gentle, non-stripping morning cleanse that leaves skin comfortable
- Low pH suits sensitive and combination skin
- Subtle tea tree freshness without heavy fragrance
- 당김 없이 편안한 순한 아침 세안
- 약산성이라 민감·복합 피부에 잘 맞음
- 무거운 향 없이 은은한 티트리 상쾌함
Cons
- Too mild to remove makeup or sunscreen alone
- Low lather feels insufficient to some
- Contains tea tree essential oil — a dealbreaker for the fragrance-sensitive
- 메이크업·선크림 단독 제거엔 너무 순함
- 거품이 적어 부족하게 느끼는 사람도 있음
- 티트리 에센셜 오일 함유 — 향에 예민하면 배제 요인
Good to know
It contains tea tree oil and a mild BHA (betaine salicylate); patch-test if you react to essential oils. As a light gel it is not designed to remove makeup or sunscreen on its own.
티트리 오일과 순한 BHA(베타인 살리실레이트)가 들어 있어 에센셜 오일에 반응하면 패치 테스트를 권한다. 가벼운 젤이라 메이크업·선크림을 단독으로 지우는 용도가 아니다.
Brand claim: COSRX markets a low-pH (mildly acidic) morning gel cleanser with tea tree oil and BHA to cleanse gently while respecting the skin's acid mantle.
브랜드 주장: 코스알엑스는 티트리 오일과 BHA를 담은 약산성(로우 pH) 아침 젤 클렌저로, 피부 약산성 밸런스를 지키며 순하게 세정한다고 내세운다.
Independent test data: No independent third-party clinical data confirmed at build time; the low-pH positioning is the brand's claim.
