The Quadrostar Pro Yellow Laser features a special wavelength of 577nm. This is an improved version of the commonly used DualYellow/Combination laser at some clinics. 

The specific wavelength of 577 nm means that the Quadrostar Pro Yellow Laser can be used to safely treat various conditions such as pigmentation, rosacea, red acne marks, uneven skin tone, etc. The majority of visible unwanted skin spots, discolorations or redness (blood vessels), are rooted in a deeper vascular network of veins which can only be reached effectively with this light wavelength.

Improve Vascular Conditions

Facial/nose veins and blood vessels – the Quadrostar Pro Yellow Laser has the highest rate of absorption in red blood cells compared to any other lasers. This results in the reduction of unsightly veins or blood vessels on the face, especially common on the cheeks and nose.

Redness and rosacea – Redness and rosacea are caused by dilated (bigger in size) blood vessels. It works by reducing the size/or completely eliminates these blood vessels.

Red marks after acne – These red marks are also known as PIE (Post- inflammatory Erythema) or Erythema post-acne. The red marks formed due to increased blood circulation at badly-inflamed areas such as moderate to severe acne and persist even after the acne heals. 

Pigmentation & Skin Rejuvenation

Pigmentation such as melasma, sun/age spots, freckles – Due to its unique wavelength, the energy from the Quadrostar Pro Yellow Laser is absorbed by both melanin (pigments) and the underlying blood vessels. This results in the breakdown of pigments and at the same time reduces the blood supply to the skin cells that produce these pigments. 

Skin rejuvenation – Apart from reducing redness and pigmentation, the Quadrostar Pro Yellow Laser’s energy is also absorbed into the dermis (skin layer) to treat and improve the skin’s support structure.


The yellow light energy from the ProYellow laser treats acne caused by P.acne bacteria by killing these bacteria, and at the same time reduces redness caused by inflammation.  The ProYellow laser also shrinks sebaceous glands that produce sebum (oil).
