PhD Trials

PhD Trials is a contract research organization, specialized in in vivo safety and efficacy studies for the cosmetic industry. Founded by a group of specialists, working in skin research for the last 15 years. We develop and performed in vivo clinical studies for claim substantiation, skin compatibility (patch test, HRIPTs, open tests) and were extensively involved in basic and applied clinical research that help us to develop new methods for efficacy substantiation of cosmetic, household, consumer and toiletries products.
