Problems solved by technology

However, the perception of color changes and intensity changes may vary between different observers, making the values ​​subjective
Because the color change and loss due to collagen is dependent on many factors (including age, skin optical and thermal properties, etc.), the measurement is not an accurate and quantitative measure of the progress of the treatment

Embodiment Construction

[0048] figure 1 A skin measurement system 110 according to the invention is schematically shown. The measurement system 110 is configured and arranged for light-based measurement of collagen inside the skin 160 . The measurement system 110 includes an optical system 130 that includes a light source 120 for emitting light over a predetermined and / or controlled source wavelength range.

[0049] Light source 120 is preferably a polychromatic source emitting a broad wavelength spectrum. In other words, the light source should not be monochromatic. Or in other words, the light source should be polychromatic or broadband or "white". The skilled person can use techniques known in the art to determine the optimum source wavelength range or bandwidth (using multiple sources simultaneously, or using a broadband source in combination with one or more suitable bandpass filters).

[0050] Examples of polychromatic or broadband light sources are:

[0051] Tungsten lamps with an emissi...

Abstract

A measurement system for light-based measurement of collagen, using a first light intensity and a second light intensity according to the invention, comprises a light source (120) for emitting a light beam having a source wavelength range and an optical system (130) to polarize light within the source wavelength range, thereby generating a polarized light beam (140), and to direct and focus the polarized light beam (140) to a target position inside the skin (160) at a predetermined focus depth below an outer surface of the skin. The measurement system further comprises a first detector (150) and a second detector.

Description

technical field [0001] The present invention relates to a measurement system for light-based measurement of collagen inside the skin. [0002] The invention also relates to a skin treatment system comprising a measurement system according to the invention. Background technique [0003] The desire to maintain a youthful appearance by reducing wrinkles in the skin is an important issue in human society. A number of techniques have been devised to achieve this goal. One technique is for example skin rejuvenation, in particular methods involving collagen denaturation, such as thermal denaturation of collagen. While some therapeutic applications are possible, the main areas of interest are in cosmetic or non-therapeutic areas. The efficacy of this approach in the skin depends on several factors, such as thermal and mechanical loads on the tissue, age of the person undergoing treatment, anatomical distribution of collagen inside the skin, disease of the skin, environmental expo...
