Abstract
A device for evaluating the creasing of the skin in vivo. A zone of the skin to be examined is creased. The zone of the creased skin is scanned with an incident luminous beam which is emitted by a light source. The light reflected by the creased skin is detected. The detected light is converted into an electrical signal. At least one parameter representing the profile of the creased skin is extracted from the electrical signal. This device makes it possible to evaluate the mechanical properties of the dermis, such as its elasticity and firmness and the aging of the skin, as well as to evaluate the effectiveness of products intended to counteract such aging.
