Cosmetics have become one of the best-selling products exported from my country. Under normal circumstances, the HRIPTRIPT skin-enclosed patch test is commonly used in cosmetics.

Makeup not only makes the face beautiful , but also protects the skin. For example, the use of sunscreen can protect the skin from the stimulation and damage of the sun; the use of massage cream can increase the elasticity of the skin and the aging of the skin; the use of toner can make the facial pores shrink, smooth and delicate.

In special cases, such as freckle -removing cosmetics and powdered (such as powder, foundation) sunscreen cosmetics, when the human skin patch test shows irritating results or the results are difficult to judge, the skin repeated open smear test should be added. The skin repeatability open test is also suitable for rinse-off products, hair dyes, hair removal products and other products. Common types of skin patch tests include closed patch test, repetitive open type test v133-8026-3640, and repetitive injury patch test.
