What is Korea changing?

Korea amended its Cosmetics Act on 30 December 2025 to introduce a new Article 4-2 dealing specifically with cosmetic safety assessments.

Under the amended Act, a Responsible Cosmetics Distributor, or 화장품책임판매업자, that falls within the new regime must prepare product-specific documentation capable of demonstrating that a cosmetic is safe before distributing or selling it.

That documentation must be reviewed by a person with the required cosmetics safety-related academic qualifications or professional experience. The legislation calls this person a Safety Assessor, or 안전성 평가자.

Korea's Ministry of Food and Drug Safety, known as MFDS, may also require safety assessment documentation to be submitted in circumstances prescribed by law.

In June 2026, the MFDS published its Guidelines for Preparing Cosmetic Safety Assessment Documentation to help businesses understand how the new assessment system is intended to operate.

Then, on 8 July 2026, it published a proposed amendment to the Enforcement Rules of the Cosmetics Act. This contains much of the practical detail needed to implement the legislation, including proposed Safety Assessor qualifications, exemptions, document retention requirements and recall-related provisions.

The formal public consultation on that draft closed on 18 August 2026.

This is being phased in, not imposed on every brand at once

The amended Act creates a staged transition rather than applying Article 4-2 to every Korean cosmetics business on the same date.

One of the key dividing lines is the Responsible Cosmetics Distributor's annual production and import value.

For businesses with annual production and import value of KRW 1 billion or more, as well as businesses registered as Responsible Cosmetics Distributors after the amended Act was promulgated, different products enter the system at different stages.

For existing Responsible Cosmetics Distributors with annual production and import value of less than KRW 1 billion, the Article 4-2 safety assessment requirement takes effect from 1 January 2031.

The Act also specifies how the threshold is calculated. In general, the previous year's production value and import value are added together. Where a full previous year cannot be calculated because of a new business, suspension of operations or similar circumstances, the actual operating period is annualised.

Smaller businesses are not operating under a lighter version of Article 4-2 before that date. They continue to be subject to Korea's existing cosmetics safety, manufacturing, ingredient, quality, labelling and advertising rules until the new safety assessment obligation becomes applicable to them.

Meet Korea's new Safety Assessor

One of the most significant features of the regime is the introduction of the statutory Safety Assessor role.

This is a new statutory function, but the material currently published by MFDS does not establish it as a separately licensed profession that every company must register with the regulator.

MFDS's published FAQ states that Responsible Cosmetics Distributors do not need to register their Safety Assessor. A business can designate a suitably qualified employee internally or use an external qualified professional.

What matters is whether that person satisfies the qualification requirements.

The July draft Enforcement Rules identify relevant academic fields including:

The draft also provides pathways for people who have relevant professional experience in cosmetics safety management.

Because these qualification criteria sit in the proposed Enforcement Rules, companies should not treat the draft wording as permanently settled until the amendment process has been completed.

What is already clear is that the Safety Assessor's role is more substantial than checking whether an ingredient appears on a prohibited list.

The underlying question is whether the cosmetic can be demonstrated to be safe when used under normal or reasonably foreseeable conditions.

What will actually go into the safety assessment?

This is where the size of the change becomes clearer.

MFDS's June 2026 guideline provides detailed guidance on preparing cosmetic safety assessment documentation, while the July draft Enforcement Rules propose the formal scope of records to be prepared on a product-by-product basis.

The assessment framework involves information concerning the finished product and its ingredients. Depending on the product and available data, relevant information can include areas such as:

Put simply, the safety file sitting behind a product may become almost as important as the formula itself.

Korean manufacturers are about to become even more important

Under the amended Cosmetics Act, the legal obligation to prepare the safety assessment documentation, have it reviewed and retain it sits with the Responsible Cosmetics Distributor.

That does not necessarily mean the Responsible Cosmetics Distributor generated all of the evidence needed to perform the assessment.

Korea's cosmetics industry is heavily dependent on specialist OEM and ODM manufacturers. Important safety information may also sit with raw-material suppliers, testing organisations and other parties in the supply chain.

MFDS clearly recognises that information flow is going to matter.

In June 2026, MFDS convened a public-private cosmetics safety assessment working group to discuss the system with industry and support practical implementation.

This issue goes to the heart of how the new regime will operate in practice.

A brand cannot assess data it cannot access.

If stability results, toxicological information, formula details or other relevant safety evidence sit elsewhere in the supply chain, the Responsible Cosmetics Distributor will need workable systems for obtaining and documenting that information.

How much is this going to cost?

There is no single MFDS-set fee for completing a cosmetic safety assessment.

The real cost will depend heavily on what data already exists for the product and what, if anything, still needs to be generated.

A company with usable stability, microbiological, raw-material and toxicological information already on file may be in a very different position from a company trying to reconstruct the safety evidence behind a product after launch.

Korean industry reporting nevertheless gives some indication of the potential cost burden.

In January 2026, Korean technology and industry newspaper Electronic Times reported that preservative efficacy, heavy-metal and microbiological testing can cost hundreds of thousands to several million won per product.

This helps explain why the cost issue matters, particularly for smaller businesses with numerous products and limited in-house regulatory infrastructure.

The same Electronic Times report described industry concerns that responsibility and costs could become concentrated on Responsible Cosmetics Distributors even though important safety data is generated during manufacturing.

This is an important distinction because the statutory obligation does not automatically shift to the OEM or ODM simply because the brand outsources manufacturing.

Could this slow down K-Beauty's famous speed to market?

Potentially.

K-Beauty's global success has been supported by an extraordinary manufacturing ecosystem where brands can work with highly specialised OEM and ODM manufacturers, respond quickly to new trends, and bring new products to market on timelines that many traditional global beauty companies would struggle to match.

The safety assessment system introduces another formal checkpoint into that process.

Once a product is within scope, the Responsible Cosmetics Distributor must prepare its safety assessment documentation and obtain the Safety Assessor's review before distributing or selling it.

In practice, that can mean gathering information from manufacturers and suppliers, identifying gaps, obtaining additional evidence where needed, organising the assessment and making sure the completed file satisfies the Korean requirements.

The July draft Enforcement Rules also propose meaningful consequences where required safety documentation is missing and a product poses or may pose a risk to public health.

Under the proposal, a cosmetic for which the required safety assessment documentation or children's product safety documentation has not been prepared or retained, and which causes or may cause a risk to public health, can fall within the recall provisions.

Separately, the draft would shorten the deadline for a recall-obligated party to submit a recall plan from five days to three days after becoming aware that the product is subject to recall.

The impact will not necessarily be equal across the market.

A large beauty group with dedicated regulatory staff, established toxicology processes and extensive safety-data libraries is likely to encounter a very different implementation challenge from a small indie brand launching multiple products with a lean team.

That could eventually change the economics of very large SKU catalogues.

Launching a new product may remain fast from a formulation perspective, but companies could become more selective if each additional SKU also creates another product-specific safety documentation burden.

While is too early to say that this will slow K-Beauty innovation as a whole it is reasonable to expect the new system will reward companies that are organised earlier, have better manufacturer relationships and maintain stronger regulatory records.

MFDS is already telling businesses to prepare

Although mandatory implementation begins in 2028, MFDS is not treating this as a problem companies should leave until 2027.

The dedicated Cosmetics Safety Assessment Support Task Force website says explicitly that the industry needs to begin securing safety data now ahead of the staged introduction.

The support programme is designed to help companies build the capacity required to respond both to Korea's new system and to increasingly demanding overseas safety regulations.

The programme advertises consulting and support for 1,500 companies, with priority categories including:

MFDS has also been providing tailored consulting to small and medium-sized Responsible Cosmetics Distributors since April 2026.

Korean reporting citing MFDS stated that, as of 31 July 2026, 588 businesses had already received consulting relating to preparation of safety assessment documentation.

That is a useful indication of the scale on which the Korean industry is already preparing.

Are Korean brands already selling in Europe better positioned?

In many cases, probably. Although it's not as simple as simply dropping the EU Cosmetic Product Safety Report into a Korean file and automatically treating it as compliant, brands already selling into markets that require formal product safety assessment may have completed much of the difficult groundwork.

They may already have substantial information relating to formula composition, ingredient safety, toxicology, exposure, microbiology, stability and other elements relevant to a product safety assessment.

Those brands should therefore be better positioned to map existing evidence against Korea's requirements than a business starting with little more than its formula and standard manufacturing paperwork.

MFDS itself is framing its support programme in the context of helping the Korean industry respond to global safety regulation and strengthening export readiness.

This could create an interesting divide within K-Beauty. Export-established brands that have spent years assembling regulatory dossiers for multiple jurisdictions may enter the Korean transition with substantial safety-data libraries already in place.

Domestic-first brands that have historically depended heavily on their manufacturer to hold technical information may have more work to do.

How long will the documentation have to be kept?

The July draft Enforcement Rules propose product-specific retention requirements for cosmetic safety assessment documentation.

The MFDS summary of the proposed amendment states that the documentation is to be retained until one year after the expiry of the use-by period or three years from the date of manufacture or import, according to the applicable provision.

Because this detail currently sits in the proposed Enforcement Rules, businesses should confirm the final wording after promulgation before locking these periods into permanent internal retention policies.

The important exception: products made in Korea purely for export

This is one of the parts of the reform most likely to be misunderstood internationally.

A product being manufactured in Korea does not automatically mean it will be subject to Korea's domestic Article 4-2 safety assessment requirement.

Article 30 of the Cosmetics Act expressly deals with products intended solely for export.

Products that are not sold domestically in Korea and are intended only for export are exempt from a number of domestic provisions, including Article 4-2(1), and may instead comply with the requirements of the importing country.

What about very small Korean cosmetics businesses?

There is an important difference between delayed application and a permanent exemption.

Existing Responsible Cosmetics Distributors below the KRW 1 billion annual production and import threshold generally receive more time, with Article 4-2 applying from 2031.

That does not mean all small businesses are permanently exempt.

The July draft Enforcement Rules propose a much narrower exclusion for certain Responsible Cosmetics Distributors with previous-year sales of KRW 1 billion or less that directly manufacture and distribute only cosmetic soap.

Again, because that exemption is currently contained in the draft Enforcement Rules, its wording should be checked after the final Rules are promulgated.

What should K-Beauty brands be doing now?

For many companies, 2028 probably sounds comfortably distant. In product-development terms, it is not.

MFDS is already encouraging the industry to start obtaining safety data ahead of implementation.

Brands should therefore be beginning conversations with their manufacturers and regulatory partners now.

Businesses with large catalogues may also want to start auditing existing SKUs rather than approaching the change product by product at the last minute.

A brand that identifies documentation gaps in 2026 or 2027 will be in a very different position from one discovering them immediately before a mandatory compliance date.

This is bigger than another compliance requirement

MFDS is framing the safety assessment system as part of Korea's response to increasingly demanding global cosmetics safety regulation. Its dedicated support programme talks openly about strengthening companies' ability to respond to global safety rules, improving export capability and helping the domestic system become established.

For an industry built around extraordinary manufacturing speed, accessible product development and an OEM and ODM ecosystem capable of turning concepts into finished cosmetics remarkably quickly, formal product-by-product safety assessment introduces another checkpoint into that model.

It also potentially changes where competitive advantage sits.

Brands with strong manufacturer relationships, organised regulatory systems, comprehensive safety-data libraries and products already capable of moving between highly regulated global markets may find the transition considerably easier.

On the other hand, the pressure may be felt more strongly by smaller companies running large SKU catalogues without that infrastructure.

None of this necessarily means Korea will lose the speed and innovation that made K-Beauty famous but it may mean that bringing a new cosmetic to market becomes a more deliberate exercise than it has historically been.

And with MFDS already telling businesses to start collecting their safety data, the Korean industry clearly is not treating 2028 as a problem for another day.
