1 comparison where the gap is too wide for us to call it a saving
  • These two listings may not be the same pack size — needs review.

    One seller lists it at 1.00x 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.

Prices checked Oct 18, 2026. Shipping and duty are shown per seller above and are not included in these figures. Some seller links earn us a commission. It never changes which seller we show as cheapest — that's computed from price data before any link is attached.

We can only find one place to buy these right now, so there is nothing to compare. We'd rather say that plainly than dress a single price up as a comparison.

Frequently asked

Where can I buy authentic IOPE?
Vetted third-party sellers we currently track for IOPE: Olive Young US, Sephora, AMORE MALL, Koreabe, Soko Glam, DodoSkin, and BuyBeautyKorea. We verify every seller before listing and never take payment to rank.
Is IOPE 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 IOPE right now?
The lowest tracked IOPE price on this page is Expert Retinol Serum Hydrogel Mask 5ea 1.05 oz.(30g) at Olive Young US — $30.00 (as of Oct 14, 2026). We rank by real landed value, never pay-to-rank.
Where is IOPE cheapest right now?
Expert Retinol Serum Hydrogel Mask 5ea 1.05 oz.(30g) at Olive Young US — $30.00 (as of Oct 14, 2026).
Which seller is usually cheapest for IOPE?
Across the 12 IOPE products we can compare today, Sephora is the cheapest on 3 of them. No seller is cheapest on everything, which is why we compare per product rather than recommending one shop.
Are IOPE products authentic on The K-Beauty Plug?
We only surface IOPE from authenticity-checked sellers — the brand's own store, K-Beauty specialists, and pharmacies. Unvetted marketplace resellers are filtered out.
How much does IOPE cost in the US?
It depends where you buy it. Across 12 IOPE products we can compare today, the cheapest seller charges an average of 16.6% less than the typical seller — about $10.98 per product, and up to $23.00 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. Sephora is usually the cheapest.
