Our philosophy makes a significant difference and helps contribute to the success of our products. Our research teams receive the necessary time and freedom to develop formulas with exceptional results that meet the highest safety standards. Our approach is respectful and rigorous, drawing on over forty years of experience creating pioneering products. Skin is an extraordinary organ, whose mechanisms are designed to protect us. This shield, however, is also vulnerable and it can become damaged over time or when it is attacked. Based on their knowledge of skin’s mechanisms, Sisley Research Laboratories strive for maximum effectiveness in each cosmetic benefit that they target. To achieve this, they develop complex formulas – that are as complete as possible – which combine the actions of a large number of key ingredients; This is a long and meticulous research process. The three parameters that help optimise our formulas’ effectiveness are concentration, dosage and complementarity. Those parameters are based on an in-depth knowledge of key combinations, which is the labour of over forty years of expertise that is continuously enriched by new discoveries. Sisley products are also exceptionally concentrated in key ingredients with some exceeding 20% of the formula. The dosage of each key ingredient is carefully studied to achieve optimum concentration, which enables maximum effectiveness while offering excellent tolerance. This intricate and precise work has built the reputation of our products.
