Description
Popular and cost-effective solution
For those with specific skin measuring needs.
In addition to the well-known parameters for measuring TEWL, elasticity and hydration. The DermaLab Single unit line of probes also features the 10 MHz and 20 MHz high resolution ultrasound probes. The 20 MHz for measuring of skin thickness as well as skin structure and the 10 MHz for visualizing subcutaneous layers and structures with a maximum of 50 mm penetration.
