Korea's functional cosmetics system

In Korea, a functional cosmetic is a category defined by the Cosmetics Act for products allowed to claim specific benefits such as brightening, wrinkle improvement or UV protection. To make those claims, a product must be reviewed by or reported to the Ministry of Food and Drug Safety. It is still a cosmetic, not a medicine.

Besides brightening, wrinkle improvement and UV protection or tanning, the categories include changing hair color, hair removal, relieving hair-loss symptoms, easing acne-prone skin, relieving itchiness by restoring the skin barrier and fading red stretch marks. Check the Ministry of Food and Drug Safety's rules for the exact scope and conditions.

A functional cosmetic helps with skin care, but it is not a medicine that diagnoses or treats disease. That is why such products may not use words like 'treat' or 'cure' in their claims. If you suspect a skin condition, see a dermatologist rather than relying on functional cosmetics.

A 2017 regulatory change moved several quasi-drug product types, such as hair dyes, hair-loss symptom relief products, hair removers and acne-care cleansers, into the functional cosmetics category. As a result, similar products may be labeled either as a quasi-drug (의약외품) or a functional cosmetic. Check the package to see which applies.

The package carries the words 'functional cosmetic' (기능성 화장품) along with the approved benefit, such as brightening or wrinkle improvement. Online product pages often show this information in the detailed specifications as well. Rather than relying on advertising copy, look for the official statement printed on the package.

Products that match a ministry-listed item in ingredients and concentrations as well as benefits, directions for use and testing standards can go through a simpler reporting process. Other products must submit safety and efficacy data, among other documents, for review. Either way, consumers see them labeled as functional cosmetics.

In Korea, products that have not been reviewed or reported as functional cosmetics are restricted from claiming brightening or wrinkle benefits. Regular cosmetics therefore tend to describe sensory effects, such as skin looking fresh or feeling moist. If you are looking for a specific benefit, check for the functional cosmetic label.

Yes. Sunscreens are functional cosmetics in Korea and display SPF and PA ratings. SPF mainly reflects protection against UVB, while PA indicates UVA protection, shown with plus signs. Labeling standards and testing methods follow Ministry of Food and Drug Safety rules, so the numbers on Korean products are regulated claims.

A shampoo labeled for relieving hair-loss symptoms is meant to support hair and scalp care. It does not mean the product treats hair loss or regrows hair. Products that only make hair look thicker by coating it are not included in this functional category. If hair loss worries you, consult a dermatologist.

Hair dyes that change hair color fall under functional cosmetics, while temporary colors that wash out with shampoo are excluded. Because hair dyes can cause allergic reactions, packages often instruct you to do a skin test before each use. Follow the directions carefully, and stop and seek medical advice if you react.

The acne-prone skin relief category is limited to rinse-off body and face cleansing products. That means leave-on products like creams or toners cannot carry this specific claim. A cleanser can only support skin care, so if your acne is severe or painful, see a dermatologist.

This category covers products that help restore the skin barrier and thereby help relieve itching and similar discomfort. They are moisturizing products for everyday discomfort and do not treat conditions like atopic dermatitis. If itching is severe or your skin oozes or cracks, see a doctor rather than relying on cosmetics.

This category covers products that help fade the red lines caused by stretch marks. It does not mean they remove older marks that have already turned white, and results vary between people. If you plan to use such a product during pregnancy, check the ingredients and talk to your doctor first.

Depilatory creams that remove body hair chemically are functional cosmetics in Korea, while tools that physically cut or pull hair are not. These creams can irritate skin, so follow the package directions closely, keep to the stated time, and avoid using them on broken skin or areas the label warns against.

It means one product has approval for two or more functional benefits. For example, a cream recognized for both brightening and wrinkle improvement is often called dual functional, and adding UV protection makes it triple functional. Check that each benefit is actually listed on the package.

Imported cosmetics must go through the same review or reporting process to make functional claims in Korea. Even if a product is marketed abroad for brightening, it cannot carry that claim in Korea without completing this process. Check the Korean labeling on officially imported products before relying on any benefit claim.

A functional label means the product's benefit was recognized under set standards, not that everyone will get the same results. How much difference you notice depends on your skin, how long you use it and how you apply it. Use it consistently, but stop if it causes irritation.

You can search reviewed and reported functional cosmetics on official Ministry of Food and Drug Safety services, such as its product information site called Uiyakpum Anjeon Nara. Search by product or company name to see approved benefits and ingredients. Menus can change, so follow the ministry's current guidance.

Functional cosmetics are a Korean regulatory category, so the same classification does not automatically apply elsewhere. Sunscreens, for example, are regulated as over-the-counter drugs in some countries, such as the United States. When using products at home, refer to your own country's regulations and labeling rules.

If you see a product that is not a functional cosmetic but claims brightening or wrinkle benefits, or advertises itself like a disease treatment, you can report it to the Ministry of Food and Drug Safety. Before buying, compare the package label with official database results. Check the ministry's website for how to file a report.
