Skin Analysis — DermaLab Combo

Cortex Technology

DermaLab Combo

A complete and powerful multi-parameter skin analysis system operated by a wirelessly connected tablet PC. This unit can be freely configured with the following parameters: High resolution ultrasound, TEWL, elasticity, hydration, sebum, pH, temperature, video scope as well as skin color (melanin and erythema).

Advanced skin analysis customized to your needs

In the DermaLab Combo we have concentrated all our knowledge in one flexible concept with the goal to be able to offer all parameters in one instrument.

The result is an instrument, which for the first time offers high frequency ultrasound for instant skin assessment in combination with more traditional skin parameters such as elasticity, hydration, sebum, TEWL etc.

Features

Customise your DermaLab Combo for the desired application by adding probes as needed.

The DermaLab Combo is well suited for scientific skin analysis and ideal for product testing as well as research work.

Operation of the instrument is highly intuitive, fully touch-screen controlled and the gathered data may easily be exported for further processing.
