Korea MFDS Cosmetics Advertising Violations: A 178-Ad Case
RU Статья пока только на английском.
Сайт на русскомContents · 5 sections
In short: most Korea MFDS cosmetics advertising violations are claims that make a cosmetic sound like a medicine. MFDS is Korea’s Ministry of Food and Drug Safety.
In the MFDS announcement of 24 July 2026, 142 of 178 flagged ads (80%) were of that kind, and MFDS did not stop at the online resellers: it traced the products back to the companies legally responsible for them and referred 23 of those companies (33 ads) to regional offices for inspection and administrative action.
This case uses only what the MFDS press briefing states: “Cosmetics that prevent vaginitis and treat acne?” 178 cosmetics ads disguised as medicines caught1 (Korean; Cosmetics Policy Division and Cyber Investigation Team, 24 July 2026). MFDS did not publish company names, and we do not name or assess any company.

Process: how the inspection worked
MFDS says it ran the check because some companies were suggesting internal vaginal use of cosmetics, or advertising pain relief or acne prevention and treatment in ways that could be mistaken for medicines. The briefing cites Article 2 of the Cosmetics Act, under which cosmetics are products applied to the outside of the body.
The inspection had two stages:
- Resellers first. Ads by general online sellers (businesses registered only for mail-order sales) were flagged and blocked.
- Then the responsible seller. MFDS traced each product to its cosmetics responsible seller, the company registered with MFDS that answers for the product’s safety, quality and labelling. That step found 10 more improper ads posted by the responsible sellers themselves.
An attachment to the briefing explains why the same body area can fall under three regimes. A product that treats a disease such as vaginitis is a medicine. Purified water sold with a douche device for internal cleansing is a medical device. A wash used only on the external genital area is a cosmetic, and cosmetics may not be used internally.
Result: blocking and administrative action
The briefing records two outcomes: all 178 posts were referred for blocking, and the 23 responsible sellers face inspection and administrative action by their regional MFDS offices. The outcome of those actions was not available at the time of the briefing, so we do not report one.
MFDS said it will keep tracing ads back to responsible sellers rather than only removing reseller posts. For a brand, this means copy written by a reseller can still come back to the company responsible for the product.
What exporters can apply to their product copy
The inspection targeted Korean online ads, but the same lessons apply to the product sheets and listing copy that go to overseas buyers.
- Drop disease names and “treat” or “prevent”. The MFDS list (inflammation, skin regeneration, treats acne, anti-inflammatory) is a practical red-flag list. Similar wording can make a product an unapproved drug in the US: a public 2024 FDA warning letter treated a Korean contract-made sunscreen as an unapproved new drug because of anti-ageing and “cell recovery” claims (Warning Letter 320-24-422).
- Use functional-cosmetic claims exactly as approved. Rewording “eases acne-prone skin” to “prevents acne” was enough to be flagged. See Korean functional cosmetics for the legal categories.
- Keep evidence for every claim. Korean law lets the authorities ask for substantiation of labelling and advertising claims; our guide to cosmetic claim substantiation in Korea covers what counts.
- Give resellers a wording guide. Because enforcement follows the product back to the responsible company, it is safer to hand overseas buyers both the approved wording and a list of words to avoid.
The briefing also points readers to MFDS’s cosmetics regulatory support centre, helpcosmetic.or.kr, for Korean and overseas regulatory information.
