In vivo measurement of some elastic properties of human skin

We developed an in vivo indentometer exerting an initial pressure of 1 g/cm2 and final pressure of 10 g/cm2. The indentation so measured (by indentometry) on the forehead skin was 0.04–0.07 cm. When slightly modified (using a perpendicular null of 10 g/cm2) the same equipment measured skin slackness. We called this technique levarometry.

The effect of over 20 cosmetic raw materials from widely different sources was evaluated. Only lactic acid at pH 4.0, vegetable oil and lanolin showed any effects lasting for more than 90 minutes.

The instrument may be used to develop better, longer lasting medico-cosmetic agents.
