Good Manufacturing Practice (GMP) is a set of guidelines that ensure the quality and safety of cosmetic products. The guidelines cover various aspects of the manufacturing process, including quality management, personnel, premises, equipment, raw materials, production, finished products, quality control laboratory, treatment of products outside of specification, waste, subcontracting, deviations, complaints and recalls, change control, internal audit, and documentation.

The purpose of GMP is to ensure that cosmetic products are safe for human use and meet the requirements of the cosmetic product legislation. GMP guidelines help manufacturers to produce high-quality products that are consistent in quality and meet the regulatory requirements.

Regulators in the EU, UK, USA, Canada, Japan, Singapore and many other countries have a mandatory requirement for cosmetics manufacturers to have a GMP certificate. ISO 22716 serves as a relevant standard of compliance.

Good Distribution Practice (GDP) is a set of guidelines that ensure the quality and safety of pharmaceutical products during storage, transportation, and distribution. GMP guidelines, on the other hand, cover various aspects of the manufacturing process to ensure the quality and safety of cosmetic products.
