DEVICE FOR MEASURING SKIN ELASTICITY IN VIVO AS A MEASURE OF SKIN AGING

摘要

The invention provides a system for the in vivo measurement of the elasticity of skin using a torsional force. The elasticity of the skin is correlated with a suitably defined aging factor for the skin. This aging factor or skin age� factor may further be used to prescribe an appropriately formulated anti-aging� agent for application on the skin to reverse the effect of skin deterioration.
