My probe stops in the middle of a measurement /strange measurement curve/error message.

 Cutosonde UnteramThe most frequent reason for this is that too much air has entered the probe opening during the measurement (i. e. the probe does not sit tightly enough on the skin). Make sure that the probe is put vertically and tightly on the skin surface and hold still throughout the complete measurement. Make sure the cable is not bent.

My probe does not work anymore (check calibration is out of tolerance).

The most frequent reason for this is that too much dirt (e.g. sebum from the skin surface etc.) is sticking to the glass prisms. Please clean the probe carefully with the supplied brushes according to the instruction manual. In addition you can unplug the probe from the device and blow compressed air into the plug side. Plug it in tightly. Always quit and restart the software before unplugging the probe or plugging it back to the device.

The Cutometer® probe needs regular cleaning. If it is used frequently, we recommend cleaning it every night before stopping work with the supplied brushes. In any case let it dry completely before doing the measurement again. Should the check calibration stay out of tolerance, contact the service.

Which probe opening should I use?

This depends strongly on the skin site to be measured. For "normal" skin (e.g. on the forearm), the 2 mm diameter opening should be used. The thicker the skin, the larger the opening we recommend, e.g. for the thighs we recommend 4-6 mm diameter and for measurements on the palms or under the feet rather 8 mm.

Which setting in the Cutometer® software is the best?

The Cutometer® offers a variety of settings. The setting depends on your application/skin site. For the inexperienced user we suggest 450 mbar, suction time 2 seconds, relaxation time 2 seconds, 10 repetions.

When repeating the measurement the results are different.

This may have different reasons.

  • The pressure with which the probe is put on the skin plays a very important role. It is of highest importance to always use the same low pressure when putting the probe on the skin (provided by the spring in the probe), The more pressure used the more the skin already slips inside the probe without applying suction.
  • There is also an "fatigue" effect, when the suction is applied repeatedly, the more often it is dragged inside the probe opening the deeper it can be drawn.
  • AnotheCuto fatiguer reason is the different structure of the underlying tissue. If the measurement is performed on a bony subsurface the result might be different as on an adjacent spot where the underlying tissue is rather fat.

Please keep in mind that especially with the elasticity measurement skin sebum or products applied to the skin lead to the spoiling of the inside of the probe. The probe needs regular thorough cleaning.

Which of the many results generated for each measurement should I take into account and what do they mean?

That will be mainly up to your application. However, the most used parameters in literature are R0 (firmness), R2 (gros elasticity),  R5 (net elasticity), R7 (elastic portion) and R9 (fatigue). A detailed explanation on the Cutometer® , the viscoelastic propiertes of the skin and the different measurement parameters can be found in the instruction manual for the Cutometer® dual MPA 580. It can be downloaded in the Download section at "Operating instructions" (password for our customers is neccessary).

How can I get my measurement results in Excel?

You can display up to 4 measurement curves together on the screen. By pressing the "Excel" button, you can bring them in one Excel sheet (either the data of the curves: penetration depth in mm/ms or the results (R, F and Q values for each curve).

Please read the instruction manual for the details.

What is elasticity and viscoelasticity?

Elasticity defines the quality of a material (e.g. the skin) to change its shape under application of a force and to return to its original shape when the force is ceased to be applied. To make this clear we could Kneteballontake a balloon and try to change its shape by pressing our finger into the surface. As soon as we stop pressing, the balloon returns completely to its original shape. This means the balloon's skin is 100% elastic.

The definition plasticity means the opposite of elasticity. E.g. plasticine changes its shape under pressure; ceasing the pressure, it does not return to its original shape but stays completely deformed.

Human skin is neither pure elastic (i.e.balloon) nor pure plastic (i.e. plastiline). It is composed of the both, therefore we talk about viscoelasticity of the skin.

This viscoelasticity of skin surface is determined by the elastine and collagen fibres. In younger skin these fibres are dispersed beneath the skin surface keeping it firm, supple and elastic.

With skin ageing, an additional influences like UVA light, mechanical and chemical strain, nicotine, alcohol, genetic predispositions, diseases and many others, the network of fibres gets more stiff and clustered, thus leading to skin slackening and wrinkle formation.

The measurement of the skin's viscoelastic properties are therefore a true indicator for the true biological age of the skin.
