| Korea vs export | Confirmed minor discrepancy, source-verified but of uncertain cause. Comparing the declared ingredients on the Korea Olive Young listing against the brand's own US site (cosrx.com) on 2026-08-27: the KR list has 23 ingredients in an order matching the US list, but the US list has one additional ingredient — Sodium Chloride, positioned 4th — that does not appear anywhere in the KR list. Everything else in both lists is identical in content and order. This could reflect an actual minor formula difference (e.g., a viscosity-control salt added for the US market) or a listing that is slightly out of date; the discrepancy is reported as observed, not with an asserted cause. |

Is it OK for sensitive skin?
Declared facts only, not a suitability verdict: no fragrance listed; no labeled fragrance allergens declared; no denatured alcohol listed. No irritation-related fact here implies suitability for any skin type.
Can I buy it outside Korea?
International shipping: Amazon; Sold in Korea only: Olive Young Korea; Shipping scope unverified: COSRX official site (cosrx.com), Soko Glam; Global price: US$14.00 (list, cosrx.com).
Is the Korean version of COSRX's Low pH Good Morning Gel Cleanser different from the US version?
There is one verified ingredient discrepancy — the US site's (cosrx.com) declared ingredient list includes Sodium Chloride, which does not appear on the Korea Olive Young listing's declared ingredient list, as compared directly on 2026-08-27. All other ingredients match. Whether this is an active formula difference or a listing update lag is not confirmed.
Is it vegan?
No vegan certification mark appears on COSRX's own US product page as of 2026-08-27.
Is it cheaper in Korea?
Yes, at list price — 9,900 KRW (roughly on par with, or below, USD $14.00 list once converted) in Korea vs $14.00 list / $11.20 sale on the brand's own US site, for the same 150ml size.
