Rainer joined Pentapharm, Basel, as a research chemist in 1982. He became head of the “Natural Ingredients” R&D group in 1987 and worked on isolating and characterizing active compounds and fractions derived from biological materials. In 1992 Rainer was promoted to Vice President.
In addition to his research activities, Rainer played a leading role in establishing, implementing, and improving the innovation process, including ideation, project, and product management. In 2000 he took over as Chair of the steering committee for the “Cosmetics” business unit and was responsible for shaping the project roadmap and project portfolio. In 2007, when DSM acquired Pentapharm, he turned his focus more to skin research and biology.
Over the past 30 years, Rainer contributed to the development and launch of dozens of products for the cosmetics, diagnostics, and pharmaceutical industries and has acquired significant expertise in biology and care of skin.
To find new targets for future skin care concepts and novel techniques for data presentation and visualization, he often takes part in academic research projects. The main topics of these projects are epidermal barrier functions, dry skin, and aging of the dermal-epidermal junction; the characteristics of different skin types and ethnic groups are always in focus.
Rainer co-edited the book “The Essential Stratum Corneum” and has published numerous scientific papers.
