Chromophores laser
WebChromophores in tissue are important for use with lasers in the visible light range. Chromophores may be endogenous, as with melanin and hemoglobin or exogenous, … WebWhat makes the skin so susceptible to laser treatment is that it contains several chromophores. These chromophores are predominantly haemoglobin, melanin, water and foreign bodies. The chromophore haemoglobin will selectively absorb light at 595nm (if using a pulsed dye laser) and the heat generated will potentially destroy the blood vessel.

Finally, on the basis of our ... WebThe laser photons are absorbed by chromophores, resulting in the target heating and localized damage. Laser irradiation alters cellular metabolism and cellular functions. These alterations may be accompanied by undesired side effects which can be monitored via metabolites level change in the body.
WebFeb 26, 2015 · Laser treatments are based on the principle of selective photothermolysis. Light-absorbing pigments in the skin, called chromophores, selectively absorb light energy and convert it to heat in the targeted lesions. The lesions are heated, damaged, and eliminated, while the surrounding skin is left unaffected. WebMar 31, 2016 · View Full Report Card.
