How it works
Rough texture and congested pores are often met with a nightly leave-on acid serum rather than a rinsed-off step. This formula builds on rice seed water and rice extract, saving glycolic and salicylic acid for the final stretch of a 48-entry list. Niacinamide and a run of hyaluronate forms cushion those acids rather than leaving skin unbuffered. Rinsing off rather than staying on overnight keeps the acid contact time shorter than a leave-on treatment. Massage it over damp skin a few times a week, then rinse and follow with moisturizer.
Key benefits
- Rice appears as both seed water and extract on the list
- Glycolic and salicylic acids handle the visible smoothing
- Inositol, the second half of the name, is on the list

COSRX RED RICE INOSITOL Exfoliating Care Pore Wash-Off Peel Serum
What is this wash-off peel serum actually meant to do?
Rice seed water sits ninth on the ingredient list, with inositol nineteenth and rice extract further down, giving the formula its named base. Glycolic acid and salicylic acid also appear on the list, positioned well toward the end among the final entries, alongside a run of hyaluronate forms and ceramide NP earlier on. The formula is built as a rinse-off exfoliating step rather than a leave-on serum, meant to be massaged on, left briefly, then washed away.
Is this peel serum gentle enough for sensitive skin?
No fragrance, essential oil, denatured alcohol, silicone, paraben, sulfate surfactant, mineral oil, or added colourant appear anywhere on this ingredient list. Glycolic acid and salicylic acid do appear, though both sit near the very end of a 48-entry list, well behind the panthenol, niacinamide, and multiple hyaluronate forms that make up the bulk of the formula. Anyone with reactive or acid-sensitive skin should still patch test first and start with a shorter contact time before leaving it on for the full recommended window.
Will one use of this peel serum visibly smooth my skin?
A wash-off exfoliating step like this one works through repeated, spaced-out use rather than a single dramatic result, since the acids on the list sit toward the end rather than the front of the formula. Coptis japonica root extract and dipotassium glycyrrhizate are positioned mid-list as calming support for the exfoliating step. Using it a few times a week and watching how skin responds over several weeks is the realistic way to judge whether it is working for you.
Can I use another exfoliating acid on the same night as this peel?
This is already an acid-based wash-off step, with both glycolic and salicylic acid on the list, so layering a separate leave-on AHA or BHA treatment the same night would stack two exfoliating steps at once. Niacinamide, panthenol, and the hyaluronate forms further up the list are the ingredients this formula pairs with afterward for hydration. Spacing this peel out from other acid treatments in your routine, rather than combining them in one session, is the safer approach for most skin.
How can I tell this is the real Korean-market formula and not a repackaged version?
COSRX runs its own authentication system rather than leaving it to a reseller: the verification page on cosrx.com asks for the batch number and expiration date printed directly on your unit's carton. Checking those codes against what is actually printed on your box, rather than a description in a listing, is the reliable way to confirm what you have. This bottle does not carry a barcode we can confirm here, so the batch and expiration codes remain the check to rely on.

How to use
- Use the RED RICE INOSITOL Pore Wash-Off Peel Serum in the evening, after cleansing, on damp skin.
- A thin layer massaged over the face in light circles, kept clear of the eye area.
- Leave it briefly, rinse it off, then carry on with toner, serum and moisturizer the same evening.
- Two or three evenings a week. Do not use it on the same evening as another exfoliant or a retinoid.
Worth knowing
- This formula carries an active acid, so pairing it with another exfoliant in the same routine is worth spacing out.
