The suction cup method as featured in the DermaLab Series devices has been completely redesigned to measure the actual elevation of the skin, when it is subject to a preset neg. pressure. Due to an integrated tank, vacuum is applied instantly in order to reflect the true elastic properties of the skin. Also measured is the time it takes for the skin to retract, when the negative pressure is released.
The application software allows for adjusting the neg. pressure and skin thickness according to skin properties.
To ensure un-biased readings, the DermaLab features a light weight probe which, when glued to the skin using a double adhesive sticker, eliminates movement artifacts from holding the probe.
With the probe in place, negative pressure will lift the skin and the elevation will be measured as input to calculate Young´s modulus (E).
