Cosmetic On-Site Expert Services
From GMP audits to industrial hygiene, from process optimization to finished product testing, we ensure every cosmetic product meets the most stringent safety and quality requirements.
Ensuring good manufacturing practise (GMP) is critical to successfully bringing cosmetics to market. WESSLING Cosmetic On-Site Services are built precisely for this purpose. We come to your manufacturing facility and combine independent third-party auditing, scientific testing methods, and practical technical consulting, ensuring your products remain under strict quality and safety control from the very beginning.
Our experts conduct a thorough audit of your production processes and environment according to cosmetic GMP requirements. This is not only a regulatory mandate — the Safety and Technical Standards for Cosmetics explicitly requires cosmetic production to comply with "Good Manufacturing Practice" — but also a cornerstone of brand reputation.
