## How it works

Blemish-prone skin often ends up torn between addressing active spots and calming the redness they leave behind. This serum opens on Propolis Extract, with niacinamide third, ahead of panthenol, ectoin, and the centella complex, and Ceramide NP near the end. That order pairs a soothing, barrier-minded base with niacinamide's tone-evening role rather than a harsher acid. Used consistently, marks and redness tend to look calmer without the sting some acid-forward spot products cause. Smooth a thin layer over the face or on marks after toner, morning and night, before moisturizer.

## How to use

1. Use the AC Collection Blemish Spot Clearing Serum after toner and before moisturizer, morning and evening.
2. A thin layer over the areas with marks, or over the whole face if that is where the congestion sits.
3. Toner first, this second, then moisturizer, and sunscreen last in the morning.
4. Twice a day. Do not use it on the marks alone and skip the rest of the routine; the moisturizer over the top is what keeps it comfortable.

## FAQ

### What is the AC Collection Blemish Spot Clearing Serum for?

Propolis Extract opens the list, and niacinamide sits third, ahead of panthenol and, further down, ectoin and the centella trio of asiaticoside, asiatic acid, and madecassic acid. Ceramide NP appears near the end alongside tea tree leaf oil. That order describes a serum built around a propolis and niacinamide base for blemish-prone skin, with a barrier-supporting lipid layered in behind them.

### Is this serum suitable for reactive, blemish-prone skin?

The list has no fragrance, no denatured alcohol, no added silicone, no paraben, and no mineral oil. That combination suits reactive, blemish-prone skin looking for a fragrance-free, silicone-free serum rather than a heavier treatment product. Anyone managing an active, diagnosed skin condition should still read the full list above against their own known triggers.

### How soon will lingering marks look better with this serum?

Niacinamide and the centella complex work toward a more even look over repeated applications rather than a single use, and ectoin's comforting effect on stressed skin follows the same pattern. Marks that have already settled tend to fade gradually across weeks of consistent morning and evening use, not overnight. Sporadic use produces a slower, less consistent result than a steady routine.

### Can I layer this serum with a separate spot treatment?

Applied after toner and before moisturizer, this serum is built to sit early in a routine rather than replace a dedicated spot treatment. It can be smoothed either as a thin layer over the whole face or focused on areas with lingering marks. Whether a separate spot treatment pairs well on top depends on that product's own ingredient list, which this formula cannot speak to.

### How do I check that this bottle is the genuine Korean-market AC Collection serum?

The bottle carries its original Korean-market barcode, 8809598450561, unaltered from the version sold in Korea. COSRX runs its own verification program rather than relying on a reseller's claim: the batch number and expiration date printed on your bottle can be entered on COSRX's verification page at cosrx.com. Read those two figures off the bottle in your hand, since that is what the check is actually for.
