What Should Skincare Brands Know Before Entering the South Korean Market?-Chongsheng-Leading Chinese Cosmetic OEM & ODM Factory

South Korea is one of the most active cosmetics markets in Asia, but it runs on its own regulatory track. Before a foreign skincare product reaches Korean shelves, the brand usually has to lock in three things in order: a local responsible person in Korea, the right classification (general or functional cosmetic), and the documentation MFDS expects for that classification. Get any of those wrong and the timeline slips, or the product gets pulled at customs.

Below is the order of decisions a brand should make, and the most common pitfalls that delay launches into the South Korean market.

Is your product a general cosmetic or a functional cosmetic?

Korea splits cosmetics into two legal categories. The split is sharper than in most other markets because each category has a different review path, a different timeline and a different cost.

General cosmetics cover everything that does not claim one of the 11 functional effects MFDS defines (whitening, wrinkle improvement, UV protection, hair colour change, body hair removal, hair loss alleviation, acne alleviation, skin barrier restoration, stretch mark reduction, and a small number of sub-categories). General cosmetics go through a notification procedure with KPTA, not a formal MFDS review.
Functional cosmetics are products that claim any of those 11 effects. Each functional claim has to be reviewed or reported to MFDS before the product ships, and supporting efficacy data is usually required.

If your product positions itself around brightening, anti-aging, sun protection, hair density or anything that touches a functional effect, classify it as functional from day one. Reformulating later to remove a functional claim is doable but expensive, because it usually means removing or substituting the active and redoing the substantiation file.

Who handles the Korean-side paperwork?

Korea requires a local responsible person for every imported cosmetic. That person is a Korean-registered cosmetics distributor or importer who becomes legally accountable for the product in the Korean market: regulatory compliance, labelling, post-market surveillance, complaints and any recall.

A few practical points:

The local responsible person is not optional. Overseas brands cannot file directly with MFDS without a Korean entity acting on their behalf.
The choice of partner affects more than paperwork. Many local distributors also run warehousing, customs brokerage and channel sales, so the commercial terms of that partnership often determine margin on the Korean side.
Responsibility does not transfer to the brand after launch. The local partner stays on the hook for recordkeeping and reporting for at least five years under current rules.

What documents do you need before the first shipment?

The standard customs advance notice goes through KPTA and requires:

A Certificate of Manufacture (issued in the country of origin, notarised).
A Certificate of Free Sale (also notarised in the country of origin).
A TSE/BSE declaration covering any animal-derived ingredients.
A Korean-language label draft that meets Article 10 requirements (product name, distributor and address, full ingredient list, net content, batch number, expiry or period-after-opening, price, and either the "Functional Cosmetic" marking for functional products or the relevant warnings).
Microbiological, heavy metal and stability test reports.
For functional cosmetics: efficacy data, typically either a human clinical study or an in vitro study depending on the active and the claim wording.

Notarisation is the step that surprises first-time exporters. Certificates issued overseas usually need to be legalised at a Korean consulate or through an apostille, depending on the country of origin. This adds weeks and is the single most common reason first shipments miss their planned launch window.

What does the MFDS review actually check for functional claims?

MFDS does not check whether the active works in a scientific sense. It checks whether the claim is substantiated for the specific formulation, at the specific concentration, on the specific product type. Three things tend to drive the review outcome:

Active and concentration match the claim. If you use a whitening active outside the range MFDS recognises for that active, you cannot rely on published literature alone. You will need your own human or in vitro data.
The claim wording stays inside the functional category. Language that suggests medical or therapeutic action will get the application rejected even if the supporting data is solid.
The substantiation file matches the label. The label, the application form and the data package all have to point to the same effect. Inconsistency between them is a common reason for a second review cycle.

There is a practical shortcut. If your functional product uses an active and a concentration that appears in the KFCC (Korea Functional Cosmetics Code) appendix 4 list, the safety data requirement is simplified and the product can move to a reporting path instead of full review. Confirming whether your active is on that list before you start substantiation work can save several months.

What has changed in Korean cosmetics regulation recently?

Three shifts in 2025 and 2026 are worth flagging for brands planning a launch:

Natural and organic claims have been phased out. As of August 2025, the natural and organic categories no longer exist for cosmetics in Korea. Products that previously carried those claims have been reclassified, and new launches cannot use those terms on packaging or marketing.
Mandatory safety assessment is in force. From July 2026, every cosmetic placed on the Korean market must be supported by a documented safety assessment, reviewed by a qualified expert. This aligns Korea more closely with the U.S. MoCRA framework and the Chinese system.
UV filter limits tightened. Benzophenone-3 was reduced to a 2.4% maximum, and Tris-Biphenyl Triazine was added to the allowed UV filter list with a 10% maximum (not permitted in aerosol formats).

If your existing formulation relies on a now-restricted UV filter, or carries natural/organic language on the artwork, those will need to change before you can submit for Korea.

How long does the whole process take?

The honest answer is that it depends on which path your product falls into and how much substantiation is already in place. Indicative ranges from recent launches:

General cosmetic notification: a few weeks once the local partner, the Korean label and the notarised certificates are ready. Most of the elapsed time is documentation prep, not MFDS review.
Functional cosmetic review, using a KFCC-listed active and concentration: roughly 8 to 16 weeks, dominated by clinical or in vitro study scheduling.
Functional cosmetic review, using a new active or a concentration outside the KFCC list: 4 to 6 months and often longer. This is the path that surprises brands who assumed their published ingredient data would be enough.

Heavy metal limits in Korea are stricter than the EU for some categories (lead in clay-based powders, nickel in eye-area colour cosmetics, and certain phthalates). Confirm those limits against your product type before committing to a formula, because remediation at this stage is far cheaper than reformulation after a failed test.

Putting it together

A South Korean market entry runs faster when the order of decisions is respected: classify the product, pick the local responsible person, lock the Korean label, line up the notarised documents, then submit. Reverse the order and the launch date slips.
