Discover all Nescens skincare

Nescens was born in Switzerland out of Professor Jacques Proust's research into the biology of ageing, the skincare extension of the centre for the prevention of ageing he founded in Genolier. The house brings to skincare the rigour of preventive medicine: actives chosen for their documented mechanism of action, concentrations that do the work, and efficacy measured in clinical testing under dermatological supervision. Swiss cosmeceuticals in the strict sense, where evidence comes before promise.
