Corneometer CM 825 is a popular skin hydration measurement instrument
Measures the hydration level of the skin surface
What does it measure?
The Corneometer CM 825 is the most used instrument worldwide to determine the hydration level
of the skin surface, mainly the stratum corneum.
The Measuring Principle
The measurement is based on capacitance mea-
surement of a dielectric medium. The Corneometer
CM 825 measures the change in the dielectric
constant due to skin surface hydration changing
the capacitance of a precision capacitor.
Fields of Application
The hydration measurement is the basic measurement for all applications in basic research and
- Ideal instrument for formulation, claim support
and efficacy testing of moisturisers.
- It is used for objective clinical trials and their
- It gives information on the course of cosmetic
- Demonstrative to alert people to specific occupational skin hazards.
- Substances on the skin (e.g. salts or residues
of topical applied products) have only minimal
influence due to capacitance measurement.
- The modern, high quality electronics of the pro-
be allow a very quick measurement (1s).
- The measurement depth is very small
(10-20 μm of the Stratum corneum) to avoid the
influence of water in deeper skin layers.
- The probe is small and lightweight for easy handling and measurement on all body sites.
- The spring in the probe head ensures constant
pressure on the skin, enabling exact, reproducible measurements which do not influence the
- Worldwide established as “corneometry“
with a broad range of studies.
- Even used for the SKIN-B project on the ISS in
- Available for C+K MPA-System, as stand-alone
device and wireless probe.
