How does it work – The ProYellow Difference
The main difference between the ProYellow laser and other skin rejuvenation lasers is its unique wavelength. Compared to its predecessor, the DualYellow laser, the ProYellow laser has a more pure and specificwavelength of just 577nm, instead of a mixture of 532nm (green) and 577nm (pure yellow light). This specific wavelength of 577 nm means that the ProYellow Laser can be used to safely treat various conditions such as pigmentation, rosacea, red acne marks, uneven skin tone etc.
Traditionally, the most commonly used laser wavelength for the treatment of pigmented lesions (such as sun spots & age spots) and vascular lesions (or unsightly veins) has been the 532nm laser, or green laser light. Green lasers provide very good results in skin types I to III, but 532nm is no longer the ideal wavelength (or color) for targeting vascular lesions for skin types 1-IV.
The ideal wavelength is 577nm, or yellow light and until the North American debut in 2014, a pure yellow laser of sufficient power for skin rejuvenation was not available. That is until the debut of the QuadroStar ProYellow laser, the industry’s first 577nm pure yellow laser for skin rejuvenation.
The Pro Yellow wavelength (577nm) provides the best absorption when treating blood vessels. Compared to the standard green wavelength (532nm), the yellow wavelength is able to produce 40% higher absorption in blood. This translates to less required power during treatment, which in turn provides a number of significant advantages.
Apart from being at the correct wavelength, these lasers utilize proper pulse durations that ensure proper absorption by red ‘targets’ in the skin. 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. In other words, apart from having the correct yellow wavelength, the proper pulse duration is needed for it to work well.
