SpectraCam & SpectraFace
Imaging solutions to study the hemoglobin, melanin and oxygen levels in the skin
What is SpectraCam?
This is the first non-invasive polarized hyperspectral imaging system developed for cosmetic and dermatological studies. Unlike regular color images, SpectraCam allows for objective quantification of skin molecules located beneath the surface, such as total hemoglobin and melanin, and skin parameters, such as oxygen saturation.
Indeed, this portative system enables image acquisition all over the body revealing otherwise invisible parameters to the naked eye. As a result, you’ll get specific maps that visually represent the obtained results.
[Worth noting is that SpectraCam is suitable for use on phototypes I to IV.]
What is SpectraFace?
The SpectraFace system was designed to extend the capabilities of the SpectraCam from 2D to 3D imaging. While the SpectraCam excels in capturing images of flat skin areas, SpectraFace is optimized to address larger, non-flat areas, particularly the human face.
Functioning similarly to the SpectraCam, the SpectraFace system employs a non-invasive approach, capturing images at a social distance without physical contact. This unique device enables the generation of “mirror-like” full-face images, offering a comprehensive view of the facial skin components.

How do they work?
Skin chromophores, like hemoglobin and melanin, are molecules that absorb particular wavelengths of visible light. As a result, they influence the perception of skin color and need to be taken into account when studying pigmentation conditions. These molecules are also relevant for the study of skin inflammation and vascularization.
The remarkable capabilities of SpectraCam and SpectraFace in quantifying these essential molecules and assessing skin pigmentation rely on their high-resolution cameras and the use of a hyperspectral system. Analyses of standard color images fail to precisely quantify chromophores and photophores located beneath the skin’s surface since they remain mostly invisible to the naked eye. The hyperspectral imaging approach overcomes this limitation by taking into account the specific spectral absorbance of these molecules.
Hyperspectral imaging involves capturing multiple images at various wavelengths across the visible spectrum, resulting in one spectrum per pixel in the image. By doing so, the concentrations of certain skin molecules, such as hemoglobin, melanin, and oxygen, can be estimated for each pixel. This valuable information is then presented in the form of images or maps, allowing for the observation of different structures like veins, blood capillaries, pores, hematomas, and pigmented spots.
