Overview of cosmetics effects on skin, and how to measure them

Parameters collected on the skin provide a better understanding of how it functions, and of any deregulation (ageing, pathologies). There are important and necessary links between developments in fundamental research on cells, the clinical expertise of the doctor, and biometrological results (whose examinations are guided by the eye of the dermatologist), quantified thanks to scientists. Thanks to the technologies described, the sometimes spectacular effects of cosmetic active ingredients on skin constituents and functions can be demonstrated.

A multimodal, holistic assessment of patients' skin is now possible, non-invasively. Examination and clinical skills are still at the heart of the skin specialist's approach, but doctors will increasingly be surrounded by engineers and scientists as they care for their patients. The dermatologists and cosmetologists of the...
