Hyperspectral assessment of acne skin exposed to intense pulsed light (IPL) intense pulsed light in acne treatment.

Background: The mechanism of intense pulsed light action on the skin is based on selective photothermolysis. The light delivered to the tissue is scattered and absorbed by chromophores that absorb a beam of radiation of a specific length. The skin reflectance changes depending on the physiological state of the tissue, as shown by the hyperspectral camera.

The assessment of moderate acne vulgaris face skin using blood perfusion and hyperspectral imaging-A pilot study.

Background: Microcirculation is the flow of blood through the smallest vessels in the circulatory system. Capillaries respond to various pathologies much earlier than arteries and veins, the changes which indicate that the disease is already developing. Careful monitoring of the functioning of the capillary system often allows the detection of in vivo disorders at an early stage.
