7.5.1 Hemoglobin and Melanin

Hemoglobin and melanin are the primary absorbers for wavelengths ranging from 520 nm to 800 nm. Depending on the type of pigment or vessels to be treated, the correct device should be used. For discrete smaller (0.1–0.6 nm) telangiectases, the devices that can be used include the pulsed dye laser (PDL), the potassium titanium oxide phosphate (KTP) laser, or intense pulsed light (IPL). For larger vessels (> 1 mm), the Nd:YAG laser is preferred with the smallest fluence and smallest spot sufficient for closure.

The improvement of the vessels and pigment is obtained by the direct heating of melanosome or HgB. Adequate pulse widths range from 0.45 to 50 ns and can be delivered by either the explosive Q-switched nanosecond (10−9) pulses, or by a gentler heating with millisecond (10−6) pulses.

Do’s Do encourage male patients to remove unaesthetical telangiectasias and hyperpigmented spots with lasers or IPL.
