Cosrx Clarifying
The COSRX clarifying range gathers the brand's exfoliating toners and pad in one place, built around AHA and BHA chemistry that loosens dead surface cells and clears congested pores. The Aha/Baja and AHA BHA Clarifying Treatment Toners come in 150ml bottles, while the One-Step Original Clear Pad ships 70 pre-soaked sheets for swipe-and-go use. These are the formulas COSRX fans reach for when skin feels rough, looks dull, or breaks out around the nose and chin.

How to use COSRX clarifying toners and pads
COSRX built its reputation on simple acid formulas that do one job well. This collection holds three of them: two 150ml treatment toners and a 70-sheet pad. Here is how each one fits into a routine and when to reach for which.
AHA and BHA, and why both appear here
AHA (glycolic and similar acids) works on the skin surface, lifting away dead cells that make the face look dull. BHA (salicylic acid) is oil-soluble, so it travels into pores and clears the gunk that turns into blackheads. The COSRX AHA BHA Clarifying Treatment Toner pairs both, which is why it shows up in routines for combination skin that is flaky in some spots and oily in others.
The two 150ml treatment toners
The Aha/Baja Clarifying Treatment Toner and the AHA BHA Clarifying Treatment Toner both come in a 150ml bottle. You apply them after cleansing, before serum and moisturiser. Decant a little onto a cotton pad or palms and press it in. They are leave-on toners, not rinse-off, so the acids keep working while the rest of your routine goes on top.
The One-Step Original Clear Pad
The One-Step Original Clear Pad gives you 70 sheets already soaked in a clarifying solution. Swipe one across the face after washing. It suits anyone who wants exfoliation without measuring liquid, and it travels well because there is no bottle to leak. One jar lasts a couple of months at every-other-day use.
How often to use acids
Start two or three times a week and watch how skin responds. Acids can sting or flake if you go daily straight away. Once your skin is used to them, many people move to nightly use of one product. Do not stack all three on the same evening: pick a toner or the pad, not both at once.
What to layer on top
After a clarifying step, follow with a hydrating toner or essence, then a moisturiser. Acids can leave skin feeling tight, so the moisture layer matters. If your barrier feels raw, drop back to fewer acid days rather than pushing through.
Sunscreen is not optional
AHA in particular makes skin more sensitive to UV. Use these toners and the pad at night, and wear sunscreen every morning. Skipping SPF undoes the brightening work and raises the risk of irritation and dark marks.
Who these suit
Reach for this range if you deal with clogged pores, an uneven texture, or dullness. If your skin is very dry or reactive, introduce acids slowly and patch test first. Sensitive skin can still use them, just less often and with plenty of moisture afterward.

FAQ
Frequently asked questions
What is the difference between the two COSRX clarifying treatment toners?
Both are 150ml leave-on toners. The AHA BHA Clarifying Treatment Toner combines glycolic-type and salicylic acids for surface and pore exfoliation in one step. The Aha/Baja Clarifying Treatment Toner is the related acid toner in the same line. If you want both surface brightening and pore clearing, the AHA BHA version covers both at once.
How many sheets are in the One-Step Original Clear Pad?
Each jar holds 70 pre-soaked pads. At every-other-day use that lasts roughly two to three months. The pads are ready to swipe straight from the jar, so there is nothing to pour or measure.
How often should I use these COSRX acid products?
Begin with two or three nights a week. Once skin tolerates them, you can move toward daily use of a single product. Avoid using a treatment toner and the clear pad on the same night, since stacking acids raises the chance of irritation.
Can sensitive skin use COSRX clarifying toners?
Yes, but go slowly. Patch test first, start once or twice a week, and follow with a rich moisturiser. If you notice stinging that does not settle or persistent redness, cut back the frequency. The clear pad is often gentler to control because you can swipe lightly.
Do I need sunscreen with these clarifying products?
Yes. AHA increases UV sensitivity, so use these at night and apply sunscreen every morning. Without SPF you risk irritation and dark spots, and you lose the brightening benefit the acids give you.
