COSRX, the Full Guide: Snail 96, Low pH, BHA and What to Buy First
Why COSRX's single-hero formulas — Snail 96, Low pH cleansing and the cult BHA liquid — earned their status, and what to buy first for your skin concern.
COSRX — short for Cosmetics + RX, as in prescription — is the Korean skincare brand that built a global following on one simple promise: a single hero ingredient per formula, at an honest concentration, with nothing added to distract it. The Advanced Snail 96 Mucin Power Essence, the Low pH Good Morning Gel Cleanser and the BHA Blackhead Power Liquid are among the most repurchased products in K-beauty, and COSRX is the largest brand on Skin101's shelves in Israel, with nearly fifty products covering every step of a routine. This guide maps the lines — and answers what to buy first, depending on what your skin is asking for.
- •COSRX stands for Cosmetics + RX — minimalist formulas built around one hero ingredient at a meaningful concentration.
- •Advanced Snail 96 Mucin Power Essence contains 96% snail secretion filtrate; the Advanced Snail 92 All in One Cream carries 92%.
- •The Low pH Good Morning Gel Cleanser has a mildly acidic pH similar to healthy skin, so it cleanses without stripping.
- •BHA Blackhead Power Liquid is the cult liquid exfoliant that built the brand's reputation for blackheads and congested pores.
- •COSRX is the biggest brand at Skin101 in Israel — from pimple patches to the newer peptide and vitamin C generation.
The Snail 96 universe
Snail mucin is the ingredient that made COSRX famous, and the numbers on the labels mean exactly what they say. The Advanced Snail 96 Mucin Power Essence is 96% snail secretion filtrate in a lightweight, serum-like texture that hydrates deeply, supports skin recovery and layers under anything without stickiness — the closest thing K-beauty has to a universal first serum. When skin wants the same comfort in a richer step, the Advanced Snail 92 All in One Cream carries 92% of the same filtrate in a bouncy, non-greasy cream that seals the routine morning or night. Together they are the definition of a starter Korean routine: one essence, one cream, and a glow that shows up within weeks.

Low pH, liquid acids and the patch in every drawer
The rest of the cult was built at the sink. The Low pH Good Morning Gel Cleanser washes with a mildly acidic pH similar to healthy skin's own, with tea tree oil and a whisper of BHA — the reason morning skin feels refreshed rather than tight, and the reason this gel became a global bestseller. Two or three evenings a week, the BHA Blackhead Power Liquid works inside the pore, dissolving blackheads and excess sebum; with consistent use, texture smooths and pores look visibly tighter. And for the blemish that arrives anyway, the Clear Fit Master Patch is an ultra-thin, transparent hydrocolloid dot that flattens spots discreetly — thin enough to wear under makeup through a full workday.

The new generation: peptides and 23% vitamin C
The newest COSRX generation moves from soothing into performance. The Advanced Vitamin C 23 Serum delivers 23% pure vitamin C — one of the highest concentrations in K-beauty — aimed at stubborn dark spots and dullness, and best reserved for skin already comfortable with actives. The 6 Peptide Skin Booster Serum takes the opposite temperament: a generous 150ml of six peptides in a watery booster that firms, plumps and smooths early lines, gentle enough for every day. Between the two sits the quiet logic of the whole brand — name the concern, and there is one single-minded formula for it.
What to buy first
Start where your skin complains loudest. Dehydrated, dull or post-blemish skin: Snail 96, adding the Snail 92 cream when nights turn dry. Oily skin, blackheads or congestion: the Low pH cleanser plus the BHA liquid, introduced slowly. Sudden breakouts: keep the patches in the drawer before you need them. Early lines and lost bounce: the 6 Peptide booster. Stubborn pigmentation: Vitamin C 23, always with daily sunscreen. Every one of them is available in Israel at Skin101 — and because COSRX formulas are deliberately minimal, they combine into a routine without fighting each other.
Why buying from the official importer matters
Counterfeit K-beauty is a real problem — the bestselling serums and sunscreens are exactly the products faked most often, and a convincing box tells you nothing about what's inside. Every item at Skin101 arrives through the brands' official importer in Israel and carries the importer's stamp with the official usage instructions on the packaging. It's the simplest authenticity check there is: look for the importer's label, and when a deal elsewhere seems too good, ask why.
Frequently Asked Questions
What does COSRX stand for?+
COSRX combines Cosmetics and RX, the pharmacy symbol for a prescription — a nod to the brand's philosophy of minimalist, problem-focused formulas built around one hero ingredient at a meaningful concentration.
Is snail mucin suitable for sensitive skin?+
Generally yes — snail secretion filtrate is a hydrating, calming ingredient that most skin types tolerate well, which is a large part of why Snail 96 became a global staple. As with any new product, patch test first and introduce it into the routine gradually.
How often should I use the BHA Blackhead Power Liquid?+
Start with two to three evenings a week on clean, dry skin and build up only if your skin stays comfortable. Skip other exfoliants on the same night, and wear sunscreen daily — a rule that applies to every liquid exfoliant, not just this one.
