Measurement device for skin properties and non-invasive treatment device

Abstract

The application provides a non-invasive measurement device () and method for the measurement of skin properties using laser light, the device comprising a probe module () and an imaging module (). The application also provides a non-invasive treatment device () and method comprising the measurement device/method. The probe module () provides a probe light beam () that enters the skin along the probe axis (). The probe light beam () is separate from any treatment radiation beam (), so that the probe light beam () can be optimized for the measurement. A more reliable skin measurement system is provided because it measures a plurality of positions along the probe axis (), within a probe region (). The measurement device and method may also comprise a treatment module () or treatment step. The skin parameters measured may then be directly used to control the treatment parameters. This results in a skin treatment device () being provided that is both effective and delivers reproducible results.
