COSRX SALE
10% Off All COSRX Products
Now through September 30, 2026. Every product in the COSRX collection is included — cleansers, toners, essences, serums, ampoules, moisturizers, sunscreen, masks and the PEPTIDE-132 hair care range.
What Should You Shop During the COSRX Sale?
Rather than walk you through all seventeen, here are eight that cover the steps most routines are actually missing.
COSRX Advanced Snail 96 Mucin Power Essence
Best for: Dewy-looking hydration before your cream
The COSRX product most people have been meaning to try. A lightweight essence built on 96% snail secretion filtrate, and the one that made the brand famous.
COSRX Hyaluronic Acid Hydra Power Essence
Best for: Lightweight hydration without the snail mucin texture
Same routine step, more conventional feel. A good pick if slip-textured products are not for you. $17.50.

COSRX The 6 Peptide Skin Booster Serum
Best for: A peptide-focused step for mature skin
Peptides are gentler than acids or retinoids, which makes this an easy targeted addition if strong actives have felt like too much. $21.50.
COSRX Hyaluronic Acid Intensive Cream
Best for: Skin that feels dry by midday
The most straightforwardly moisture-focused cream in the collection, in a 100 g jar. $17.50.
COSRX Advanced Snail 92 All in One Cream
Best for: A simple moisturizing step
One product doing the work of several — the sensible choice if you know you will not keep up with five steps. $19.00.
COSRX Full Fit Propolis Light Ampoule
Best for: Dull-looking skin that wants glow
A honey-like glow step built on black bee propolis. The most indulgent product in the range at $27.00.
COSRX Low pH Good Morning Gel Cleanser
Best for: An affordable everyday cleanser
The entry point of the whole collection at $10.99, and a gentle place to start if you are new to the brand.
COSRX Aloe Soothing Sun Cream SPF50
Best for: Your final morning skincare step
Lightweight, no white cast, and a travel-friendly 50 ml size that makes reapplication realistic. $12.95.

Already Use COSRX? This Is a Good Time to Restock
If COSRX is already part of your routine, you probably know exactly what you are running low on.
- Down to the last of your Snail 96 Essence?
- Cleanser nearly empty?
- Want a backup sunscreen before the next trip?
- Been meaning to add a second cream for the colder months?
With 10% off through September 30, restocking now costs less than restocking in October.
New to COSRX? Start With One Step
A sale is not a reason to buy a seven-product routine. It is a good reason to finally fix the one step your routine is missing.
- Need more hydration? Start with an essence — the COSRX Advanced Snail 96 Mucin Power Essence or the COSRX Hyaluronic Acid Hydra Power Essence.
- Need a moisturizer? Choose a cream — the COSRX Hyaluronic Acid Intensive Cream.
- Interested in peptides? Consider the COSRX The 6 Peptide Skin Booster Serum.
- Need a daily cleanser? Start there — the COSRX Low pH Good Morning Gel Cleanser.
- No sunscreen yet? The COSRX Aloe Soothing Sun Cream SPF50 is the easiest habit to add.
One product, used consistently, will do more for your skin than five bought in a hurry.
