What is Pro Yellow Laser?

Pro Yellow Laser is a German-engineered Quadrostar that is an improved version of the commonly used Dual Yellow/Combination laser at some clinics. Because of its special wavelength of 577nm, this Pro Yellow Laser represents a gold standard for vascular treatments and epidermal pigmentation treatments. Ultimately, it is a treatment used to treat pigmentation and promote skin rejuvenation.

Why the colour yellow?

The colour yellow has the ideal wavelength of is 577nm and the QuadroStar Pro Yellow Laser was the first pure yellow in the industry that was successful for skin rejuvenation. This Pro Yellow wavelength provides the best absorption when it comes to treating blood vessels.

When compared to the standard green wavelength of 532nm, the yellow wavelength has the ability to produce 40% of higher absorption in the blood. This also means that lesser power is required during the treatment.

How deep can the Pro Yellow Laser penetrate the skin?

Most of our unwanted dark spots, skin discolouration and redness on the skin are rooted in a deeper vascular network of veins that extend beyond the treatable depths of that the traditional green lasers of 532nm can reach. The inability to address these areas can result in the inability to effectively treat deeper pigmented and vascular issues.

Hence, comes the part of the Pro Yellow Laser. This yellow laser has the ability to penetrate much deeper than the standard green lasers that simultaneously address both visible lesions and underlying vessels. Not only that, but this also allows for safer treatment of various skin concerns for light and dark skin.

What are the areas or skin concerns benefit from the Pro Yellow Laser?


The yellow light from the laser helps treat acne by killing the bacteria that causes it. It also reduced the redness and inflammation simultaneously. Other than that, it also shrinks the sebaceous glands that produce the sebum.


With a specific wavelength, the energy from the Pro Yellow laser is absorbed by both the melanin pigments and underlying blood vessels. Hence, resulting in the breaking down of pigments and reducing the blood supply to the skin cells that produce the pigments.

Skin rejuvenation

This laser energy from the treatment is absorbed into the dermis layer of the skin to not only treat, but improve the support structure of the skin. Hence, making look brighter and feel much tighter and firm.

Facials veins and blood vessels

As this laser has a high rate of absorption in the red blood cells than any other lasers, it helps reduce the unsightly veins or blood vessels that are on the face. Especially areas like the nose and cheeks.

Redness & rosacea caused by dilated blood vessels

This yellow laser helps by reducing the size or eliminating the blood vessels that would result in reduced redness on the skin and an even-toned complexion. Also, this laser reduces the red marks that are caused by increased blood circulation by reducing the blood vessels in the area.

Vascular conditions

Vascular lesions are caused by small and dilated capillaries that appear as red spots or visible threads on your skin. The Pro Yellow Laser can effectively treat them by shrinking the vessels with its yellow light, without causes damage to the capillaries.

How does Pro Yellow Laser work?

The main reason the Pro Yellow Laser works well is that it is able to penetrate deeper into the tissues. Green lasers with wavelengths of 532nm were tested to treat pigmentation but it did not reach deep enough into the skin to effectively reach the pigmentation and blood vessels that were contributing to these issues.

Also, compared to the standard green wavelength, the yellow wavelength is able to produce 40% higher absorption in the blood. This then leads to the advantages of having better comfort during the procedure, a shorter healing time, reduced risks of side effects like blisters burns or pigmentation chance. The other advantages include the ability to treat darker skin types compared to other lasers and sensitive skin like those with rosacea or eczema.
