These are some of the safety tests typically conducted at Shiseido:
1. Irritability on the skin is predicted using “artificial skin,” which is made from skin cells and collagen.
2. Patch testing, which tests for redness and swelling of the skin in an area with a test product attached, is performed to confirm that the product does not cause irritation to the skin.
3. Stinging testing is performed to confirm there is no irritating sensation on the skin, such as an itching or burning sensation, following the application of the test product.
