The friction measurement gives a measure of the smoothness of the skin. This is related to how dry the skin is as well as the wrinkles that are present. So the friction measurement can be used to distinguish between normal and dry skin as well as skin with and without wrinkles.
The Frictiometer® can be used to assess the smoothness of the skin following application of skin care products designed to make the skin smoother. Smoother skin will have lower values.
