Measured across 73 comparable products with 2 or more sellers. Products carried by more sellers show wider spreads, so the price index figure for the same brand is higher because it counts only products with 3 or more sellers.
7 wider gaps excluded: 4 where the gap is too wide to trust; 3 where we haven't confirmed the cheaper price in the last 7 days.

4 comparisons where the gap is too wide for us to call it a saving
One seller lists it at 1.73x the other.
A gap that wide is usually a listing problem rather than a real saving, so we're showing both prices without calling one a deal. We'd rather show you the doubt than a number we can't stand behind.
These two listings may not be the same pack size — needs review.
One seller lists it at 1.07x the other, or one listing declares a multipack. A box of ten against a single unit is a pack difference, not a price difference, so we're showing both prices without calling either one a gap.

Frequently asked
- Where can I buy authentic COSRX?
- Vetted third-party sellers we currently track for COSRX: Stylevana, YesStyle, StyleKorean, Olive Young US, Amazon, Ulta Beauty, Koreabe, DodoSkin, BuyBeautyKorea, and Soko Glam. COSRX's own store also sells direct. We verify every seller before listing and never take payment to rank.
- Is COSRX on Amazon authentic?
- Only when the listing is sold by the brand or a seller the brand authorizes. Unknown third-party marketplace sellers are the counterfeit risk — check who ships the item, not just the platform, and be suspicious of prices well below every other authorized seller.
- What's the cheapest place to buy COSRX right now?
- The lowest tracked COSRX price on this page is AC Collection Acne Patch at YesStyle — $6.40 (as of Oct 8, 2026). We rank by real landed value, never pay-to-rank.
- Where is COSRX cheapest right now?
- AC Collection Acne Patch at YesStyle — $6.40 (as of Oct 8, 2026).
- Which seller is usually cheapest for COSRX?
- Across the 73 COSRX products we can compare today, Stylevana is the cheapest on 29 of them. No seller is cheapest on everything, which is why we compare per product rather than recommending one shop.
- Are COSRX products authentic on The K-Beauty Plug?
- We only surface COSRX from authenticity-checked sellers — the brand's own store, K-Beauty specialists, and pharmacies. Unvetted marketplace resellers are filtered out.
- How much does COSRX cost in the US?
- It depends where you buy it. Across 73 COSRX products we can compare today, the cheapest seller charges an average of 13.4% less than the typical seller — about $2.66 per product, and up to $7.36 on one. We measure against the median of the other sellers rather than the most expensive one, so a single overpriced listing can't inflate the figure. Stylevana is usually the cheapest. Prices checked Oct 10, 2026.
