Abstract (en)

[origin: WO9729686A1] A device for estimating (in vivo) skin wrinkling, including (a) movable means for forming wrinkles on an examined skin area (Z) in a direction parallel thereto, (b) movable means (D) for scanning the wrinkled skin area using an incident light beam (L) from a light source, (c) position sensing detectors (PSD) for recording the light (L1) reflected by the wrinkled skin, (d) means for converting the sensed light into an electrical signal, and (e) means (T) for extracting at least one representative parameter of the wrinkled skin profile from the electrical signal. A method carried out by means of the device is also disclosed. The method is useful for serially estimating the mechanical properties of the dermis, e.g. the resiliency and firmness thereof, as well as skin ageing, and for estimating the effectiveness of products intended to control same.
