Specifically Sebum:
Q: Why is offset calibration on each strip necessary?
A: - The offset calibration eliminates batch-to-batch variation on the strip to increase accuracy/repro-
ducibility.
Q: For how long do I need to press the sebum collecting strip against the skin?
A: - The time is less important if all of the absorbing area on the strip is exposed. Spend a few seconds
to roll your thumb over the back side of the absorbing strip, when pressed against the skin with mod-
erate pressure.
Specifically Elasticity:
The elasticity screen allows for adjusting the skin thickness – why?
Q:
A: - Skin thickness is a parameter in the equation for calculating elasticity. By default it is preset to 1
mm, but if the real thickness is known, it is possible to obtain a more correct elasticity measurement
by adjusting this setting. Depending on configuration, the DermaLab Mini features high resolution ul-
trasound to accurately measure skin thickness.
Q: Why change between soft/normal/firm skin?
A: - Depending on the body location and skin condition the mechanical properties of the skin varies.
This setting allows for adapting the device to the body site and actual skin condition in order to fully
utilize the dynamic range of the device, thus obtaining more precise and sensitive readings.
Specifically Dermascope:
Q: Why use polarized light?
A: - Using polarized light mimics the use of oil on the skin to eliminate surface reflections.
