The use of pulsed dye lasers is currently the treatment of choice for PWSs. The 577-nm or 585-nm wavelength selectively targets oxyhemoglobin and the 450-microsecond pulse duration is sufficient to cause intravascular coagulation without excessive heat dissipation to the epidermis or adjacent dermal structures. . . .
