Cosmetic Testing

Cosmetics are daily chemical industrial products that are spread on any part of the human body surface (such as skin, hair, nails, lips, etc.) by rubbing, spraying or other similar methods to achieve the purpose of cleaning, eliminating bad odors, skin care, beauty and modification. Since cosmetics directly act on human skin, when cosmetics have poor ingredients and improper functions, they can easily cause serious consequences such as skin allergies. Therefore, the quality and safety of cosmetics must be ensured to safeguard the legitimate rights and interests of consumers.

Cosmetic testing uses a series of physical and chemical technical means to analyze the ingredients, performance and safety of the product. Good cosmetic testing can help you conduct product quality control and safety monitoring to solve product problems in a timely manner, optimize product performance, and ensure product safety and effectiveness.

STEMart provides comprehensive cosmetic testing services to ensure that products comply with industry standards and regulations, protect the legitimate rights and interests of consumers, and establish good brand credibility.
