An arrangement for skin characterization, wherein the arrangement comprises a measurement device, and the measurement device comprises a radiation-emitting device which illuminates a skin region with radiation, and the radiation-emitting device comprises
- one or more first emitters which emit radiation in a UV wavelength range of 200 nm-400 nm,
- one or more second emitters which emit radiation in a visible wavelength range of 400 nm-750 nm,
- one or more third emitters which emit radiation in a near-infrared wavelength range of 750 nm-900 nm,
- wherein the device also comprises one or more radiation detectors which measure a reflected radiation spectrum from the skin region as the skin region is illuminated by the radiation-emitting device, and the one or more radiation detectors measure the reflected radiation spectrum in the UV wavelength range, the visible wavelength range and the near-infrared wavelength range.
A method for characterizing skin, characterized in that the method comprises the steps of:
- illuminating a first skin region in a UV wavelength range of 200 nm-400 nm, and with radiation in a visible wavelength range of 400 nm-750 nm and with radiation in a near-infrared wavelength range of 750 nm-900 nm, and measuring a first reflected radiation spectrum from the first skin region when the first skin region is illuminated,
- illuminating a reference skin region with radiation in the UV wavelength range, the visible wavelength range and the near-infrared wavelength range, and measuring a second reflected radiation spectrum from the reference skin region when the reference skin region is illuminated, and
- comparing the first reflected radiation spectrum to the second reflected radiation spectrum.
