MoistureMap MM 100

Unique Device to Look at Hydration Distribution and Texture Properties

MM100 Quadrat

The MoistureMap MM 100 is a device, featuring a capacitance based sensor comparable to the renowned L'Oreal SkinChip®* . The sensor gives graphical information on the near surface hydration distribution and the micro-topography of skin and other tissues (textiles, plants, etc.).

The Measuring Principle

MM Titel

The sensor measures the penetration of the electromagnetic field. Conductive material e.g.

MM Messprinzip

water will reflect the signal making the resulting pixel darker while non-conductive material will make the signal go farther inside and the resulting pixel will be lighter on a scale of 255 grey levels. Rather than absolute moisture figures the MoistureMap indicates the distribution of hydration on the skin surface. On the 1.8 x 1.28 mm silicon chip of the sensor, over 90,000 capacitors are located every 50 µm. The sensor is covered with a silicon oxide layer for protection.
With a special image analysis software the image can be evaluated in different ways. Together with the worldwide known and established Corneometer® for quantitative MM100 komplettassessment of the hydration level of the stratum corneum and the Tewameter® to measure exactly the transepidermal waterloss and assess the skin barrier function, you can create a complete "Water Measurement Center".

Advantages of the MoistureMap

  • Perfect addition to the quantitative measurement, as it shows the distribution of the water on the skin surface
  • Easy and quick to handle
  • Live stream visible in the software
  • Captured image in standard jpg-file
  • Evenness of the hydration is displayed in 5 different colours and a histogram, the ranges can be easily set by the user via one mouse click.
  • Video possible (.avi)
  • Spring loaded sensor
  • Automatic saving of the images under a study name
  • Optionally the measurement can be triggered by a footswitch
  • In vivo skin measurement and also in vitro application can be performed.
  • In addition to looking at hydration, topographic measurements (profile, corner density, anisotropy index) give interesting aging parameters.
  • Easy calibration possibility for the user
  • All results are saved in an Excel®-file by one mouse click
  • Up to six images together with their complete results can be compared in one overview
  • The only instrument which can work side by side with the established Corneometer® and Tewameter®
  • New parameters for the software will be developed in the future

Fields of Application

Wherever skin moisture distribution plays a role the MoistureMap MM 100 is a very impressive imaging addition to the pure quantitative measurements. In literature the use of such equipment is known for efficacy testing of cosmetics & pharmaceuticals & surfactants, skin photo-aging and illustration of skin lesions and scars. Capacitance imaging has also been used to determine to map the hair moisture level.

*The MoistureMap MM 100 is licenced worldwide under the L'Oréal patent for the Skin Chip® (EP 1 438 922 B1).
A variety of articles on the measurement principle of the Skin Chip® (same as MoistureMap) has been published.

In vitro Measurements with a Special AdapterMMinvitro-Stand

With our MoistureMap in vitro Adapter (optional accessory), the probe can be mounted in the stand with the sensor pointing upwards. In addition different MMinvitroobendonor chambers are included (0.5 and 0.8 mm outlet) which can be put on the sensor surface and are retained in the adapter on top of the sensor. There is a matching lid to minimize evaporation of volatile solvents from the donor chambers. A video can show the kinetic effects of the distribution of hydration over time.
