Researcher Eun-Bi Ko

For over 3 years, the IOPE LAB has measured skin from over 3,000 people and performed meticulous analyses in order to create cosmetics that are suitable for sensitive skin that reacts to the slightest irritation. We understood that many people suffer from concerns related to sensitive skin (dryness, dead skin cells, etc.), and through research on products that can be safely used on sensitive skin, we finally developed a product line that offers sensitive solutions.

  • Allergy testing completed

    This test involves using the actual product to verify that the product is mild and non-irritating.

    Since cosmetics are products that are used over long periods of time and are often non-irritating, there are sometimes cases where abnormal reactions cannot be observed with just a primary skin irritation test. Therefore, this test checks for abnormal skin reactions through accumulated irritation testing via repeated exposure.

    It looks for any abnormal reactions after applying the product on fertile chicken eggs to check for eye irritation.
