The Pulsed Dye Laser, or PDL uses a concentrated beam of light that targets blood vessels in the skin. The light is converted into heat, destroying the blood vessel while leaving the surrounding skin undamaged.
Entails yellow light which is safe for the body and organic dye. The body absorbs the light selectively by the blood and blood vessels. By far, this has been said to be the most specific and targetted laser treatment. The lasers deliver intense yet gentle bursts of light into very targeted areas of the skin. It delivers pulsed laser energy at a wavelength of 595nm that passes through the dermis and epidermis skin layers and is absorbed by the oxyhemoglobin in the blood vessels rather than by the surrounding tissue. It is therefore considered the most specific laser currently available for the treatment of superficial vascular lesions. Pulsed dye laser treatment can be effective for a variety of skin conditions, including rosacea, facial redness, port wine stains, hemangiomas, hypertrophic scars, keloids, and telangiectasis.
