Abstract:

Oily skin can cause a variety of skin problems, and in severe cases can even lead to acne, seborrheic dermatitis and other skin diseases. People with oily skin are often troubled by greasy skin. Sebaceous secretion is affected by many factors, and the oil control mechanism of cosmetics is complex. Therefore, the oil control efficacy of cosmetics requires a comprehensive and scientific evaluation at multiple layers and dimensions. The Classification Rules and Catalogue of Cosmetics defines the oil control effect as “helping to slow down the secretion and deposition of sebum at the application site, or making the oil secretion at the application site not obvious”. The Cosmetics Supervision and Administration Regulations require that cosmetic efficacy claims should have sufficient scientific basis. In this paper, starting with the basic mechanism of sebum secretion, the requirements of domestic and foreign laws and regulations, the mechanism of oil control cosmetics, the evaluation methods and research progress of oil control efficacy of cosmetics are described, and the establishment of a more comprehensive evaluation system of oil control efficacy of cosmetics is prospected.

Key words: cosmetics, efficacy evaluation, oil control
