Quality
Assurance

DHC products are produced in plants equipped with numerous checking systems. Strict testing is employed to ensure safety and provide consumers with peace of mind.
Only products that pass all tests can be released.

We’ve earned ISO 22716:2007 international quality and safety certification. Known as the Good Manufacturing Practices (GMP) certification for cosmetics, this certification is proof that our entire series of manufacturing processes satisfies control standards.
All personnel do their jobs, paying close attention to the three fundamentals of thorough sanitation management, strict manufacturing controls, and attentive quality control.

Commitment to quality assurance

The plant includes a fully equipped Quality Management Office where quality-testing experts work to ensure product safety.

The quality control section is the only place authorized to stop the flow of cosmetics produced. We take pride in our commitment to delivering safety and peace of mind to our customers.

Tests include raw materials inspections to ensure that suppliers deliver raw materials as ordered, bulk inspections to ensure compliance with product standards, and final product inspections to check on labeling and product efficacy. Checking involves various methods, including the use of analytical equipment and sensory inspections focused on color and feel.

Production commitment

We manage production through various methods, including ensuring traceability by maintaining gaps in the lot numbers between different production lines for the same product.

We make the most of experienced personnel and advanced machinery to produce high-quality cosmetics efficiently, never missing signs of any potential issues.
