The GMPC certificate refers to the company's Good Manufacturing Practice for Cosmetics (GMPC) certification, an international standard designed to ensure that the safety, quality and hygiene of the cosmetic manufacturing process meet international standards.

GMPC certification covers many aspects of the cosmetic manufacturing process, including raw material procurement, management of production facilities and equipment, production operating procedures, product quality control, hygiene and sanitation, and personnel training. Receiving GMPC certification means that the company's production and quality management system meets international best practice standards for cosmetic manufacturing.
