WebThe skin chromophores commonly targeted by the pulsed dye laser is haemoglobin in blood. Complications result when energy intended for the target chromophore is non-selectively diffused and absorbed by surrounding tissues and structures. What is a pulsed dye laser used for? WebJan 1, 2024 · The main types of laser used for cutaneous treatments are divided according to the chromophores they target – oxyhemoglobin (vascular lesions), melanin (pigmented lesions and hair removal lasers) or water (resurfacing lasers). Ablative lasers are the resurfacing lasers, such as CO 2 and erbium:YAG lasers, which remove the epidermis.

Soft tissue chromophores consist mainly of water and hemoglobin (Hb). Laser light is absorbed differently by these particular chromophores. A hard tissue laser is used for cutting on bone, and a soft tissue laser for cutting on gum tissue.

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.
