A New Evaluation Method of Skin Plastoelasticity
The dermatologist assesses skin turgor in his patients by the simple manoeuvre of pinching the skin. The experienced finger and thumb can obtain invaluable qualitative information about mechanical functions of the skin in order to correlate them to the general clinical conditions of the patient. In fact, such functions depend on skin structure and skin structure varies in relation to a lot of factors, among which: age, sex, race, test-site, particular physiological and pathological conditions, pharmacological and/or cosmetic treatments. Raising and then releasing a fold of skin, the clinician assesses cutaneous estsensibility and plastoelasticity (that is elastic recovery and residual deformation). In an attempt at quantifying and analyzing the above mentioned mechanical parameters, we took part in the development of a pre-existing device for the objective study of skin plastoelasticity “in vivo” (1).
