We are Dermatest® – Leading the way in skin safety

Dermatest GmbH is an independent dermatological test institute based in Germany, providing preclinical and clinical testing services for the cosmetic industry. We specialize in regulatory affairs, patch tests, Safety-in-Use tests and in vitro analysis to evaluate the tolerability and efficacy of cosmetic products, materials, food supplements and consumer goods. Our services ensure that products are skin-friendly and safe for consumers. The Dermatest seal of approval labels products that have undergone rigorous, science based testing, ensuring reliability and consumer confidence. Founded in 1978 in Münster, Germany by Dr. Werner Voss, dermatologist, we were the first dermatological test institute on the domestic market.

Our extensive team of experts tests all products and materials that come in contact with skin: Cosmetic products, materials and commodities. Additionally, we offer nutritional supplement testing. We carry out these studies in our own regional test centers from a selection of over 5,000 test subjects. We test and evaluate to make products safer to use and to ensure their effectiveness is measurable and comparable. We have 45 years of experience with reliable dermatological studies.

Experts for product testing

Our regulatory affairs team ensures that your cosmetics comply with EU regulations. This includes Cosmetic product Safety report (CPSR), safety assessment, product classification, CPNP notifications, PIF compilation and consultancy on labeling, claims, or ingredients.
We provide comprehensive patch testing services to verify the safety of your products. We offer standard, photo, scarification and tape-stripping patch tests and perform them on normal, sensitive and atopic skin.
With our Safety-in-Use studies we confirm the product safety and skin tolerability under real world conditions. We design flexible studies tailored to your product’s category and objectives. In addition to irritation and sensitisation potential, the efficacy can also be analysed.
In our laboratory for in vitro analyses we test skin and eye compatibility according to OECD guidelines. Using full thickness skin models we further provide detailed insights into your product’s efficacy by e.g. evaluating collagen production.
