Apart from being at the correct wavelength, these lasers utilize proper pulse durations that ensure proper absorption by redness. Long pulse lasers are needed for hemoglobin absorption – something that short pulse lasers are not able to achieve. There are many gimmicky Gold-Toning or Yellow Light treatments – these are either Q-switched/PICO pulse durations or non-focused beams of light that are completely unsuitable for effective redness treatments.
The dual 532/1064 wavelengths target both deep and surface redness and blood vessels. It is important to understand that long-pulsed 532(green) and 577 (yellow) laser wavelengths are only effective for the surface blood vessels like these:
Deeper or bluish veins like these will require treatment by 1064 or Diode wavelength lasers:
The procedure is usually 20 minutes long, followed by a pampering facial cooling and recovery treatment. Patients may experience some redness (looks like a light blusher) immediately after the treatment which may take a few hours to subside.
"Redness or vascular pigments occur in multiple layers of the skin, just like brown pigments like melasma. Treating the superficial vessels is rarely enough to achieve complete resolution."
