Cosmetics OEM (Original Equipment Manufacturer) refers to the "original equipment manufacturing" model, which is a common business model. It involves the cosmetic brand (the client) entrusting the production process of the products to a professional manufacturer (contract factory). The latter produces the products according to the brand's formula, standards or requirements, and then labels them with the brand's trademark for sale. The core of this model is "contract manufacturing". The brand focuses on brand operation and sales, while the manufacturer is responsible for large-scale and professional production.
