1. General Introduction

South Korea adopts the negative list to regulate the use of ingredients in cosmetics. This means if an ingredient is not listed in the prohibited ingredients list (Annex 1 of Cosmetic Safety Standard) or is used under the limitation requirements for restricted ingredients list (Annex 2 of Cosmetic Safety Standard), the ingredient can be used in manufacturing a cosmetic product.

Note that toothpastes, deodorant and many other personal care products belong to Quasi-drug (click here for the QD regulation). And chemical substances used as cosmetic ingredients are exempted from the registration of K-REACH

Besides, animal testing is banned for cosmetic ingredients in South Korea. The ban on animal testing also applies to imported cosmetics. Nevertheless, MFDS also published twenty-nine guidelines on alternative animal testing methods to guide cosmetic enterprises in smoothly conducting safety tests.

2. Cosmetic Ingredients

2.1 Prohibited Ingredients

As per the provisions in Cosmetics Act, the Ministry of Food and Safety Drug (MFDS) specified 1,040 kinds of ingredients as prohibited ingredients which cannot be used for manufacturing cosmetics distributed in South Korea, such as galanthamine, gold salts, prohibited chemical substances under K-REACH, etc. These ingredients are listed in the Annex 1 of Cosmetic Safety Standard. English version is available here: South Korea: Prohibited Ingredients in Cosmetics.

2.2 Restricted Ingredients

Korean authority controls the raw materials subject to special use restriction, such as preservatives, colorants and UV-filters, by designating the restricted ingredients' scope and their usage limits.

If enterprises intend to use a non-notified preservative, colorant or UV-filter to manufacture products, or use the notified restricted ingredient for new purposes, they shall apply for MFDS recognition. The applicant shall submit an application letter, together with the following documents:

  3. Properties of the raw material;

  4. Safety and efficacy documents (applicable for the situation where the efficacy document is required);

  5. Test report of the raw material’s standard and test method.

MFDS will review the application documents and send a result notification to the applicant within 180 days. For the detailed requirements for the submission documents, enterprises can refer to Regulation on the Examination of Designation and Changes of Cosmetics Ingredient Standards.

2.3 Functional Ingredients

Following the Enforcement Rule of Cosmetics Act, functional cosmetics refer to the following items with efficacies:

  1. Cosmetics which have efficacy helpful in skin-whitening by curbing the formation of marks, freckles, etc. through prevention of skin pigmentation of melanin;

  2. Cosmetics which have efficacy helpful in skin-whitening by fading melanin pigmentation in skin;

2.4 Natural and Organic Ingredients

MFDS introduced the categories of "natural cosmetic" and "organic cosmetic" in 2018. The ingredients play a pivotal role in compliance of natural and organic cosmetics. Following the Regulations on the Standards of Natural and Organic Cosmetic Products, in a natural cosmetic product, the natural raw material concentration shall exceed 95%. The standard of organic cosmetics is stricter than that of natural cosmetics. Apart from the 95% natural raw material concentration, organic cosmetics shall contain over 10% organic ingredients.

korea-cosmetic-ingredient-001.jpgNatural raw materials refer to natural ingredients (including organic ingredients, plant ingredients, animal ingredients, and mineral ingredients), natural-derived ingredients, and water. “Organic ingredient” is a sub-category under the above-mentioned "natural ingredient". It includes the following items:

  1. organic agricultural and fishery ingredients certified by South Korean authority,

  2. organic agricultural and fishery ingredients certified by foreign authorities, and 

  3. organic ingredients certified by institutions registered with IFOAM (International Federation of Organic Farm Movements)

3. Hot Cosmetic Ingredients in South Korea 

Centella Asiatica

Centella Asiatica (A.K.A. “Cica” or "Tiger's Grass") is an important medicinal herb commonly found and used in Asia for centuries. Rich in amino acids, beta carotene, fatty acids and phytochemicals, it is famous for its strong properties in moisturizing as well as collagen and skin tissue synthesis.


Niacinamide, a form of Vitamin B3, is a hydrophilic endogenous substance. It has a host of benefits, including brightening dull skin, enhancing hair appearance, and moisturizing skin. This ingredient is specified in KCFF as a main functional ingredient in whitening cosmetics.


Mugwort, a type of "Artemisia", is still a hot ingredient in South Korea. Touted for its ability to reduce redness and sensitivity and comparable to Vitamin C in terms of antioxidant capacity, this ingredient is perfect for those with dry, sensitive, and acne-prone skin. However, as Mugwort is not a notified anti-wrinkle or anti-acne ingredient, enterprises cannot declare the relevant efficacies unless they apply for an evaluation of functional cosmetics.
