Your Guide to Pro Yellow Laser Treatment in Singapore

What is Pro Yellow Laser?

The Pro Yellow Laser is a new generation of the Dual Yellow laser commonly used by clinics for the treatment of hyperpigmentation and rosacea.

As a result of its special wavelength of 577 nm, the PRO YELLOW laser is effective in treating vascular conditions such as telangiectasia, couperosis, spider nevus, cherry angioma, venous lake, port wine stains, and red spider veins. Due to the lower melanin absorption (compared to 532 nm), it is suitable for treating darker skin types as well as requiring less fluence to achieve the expected results for hard to treat conditions such as melasma and rosacea.

Why Yellow

The colour yellow has a wavelength of 577nm which makes the Pro Yellow Laser effective for skin rejuvenation. When compared to the standard green wavelength of 532nm, the yellow wavelength has the ability to produce 40% of higher absorption so as to: 

  • minimise the risk of side effects, such as burns or darkening pre-exisiting hyperpigmentation
  • effectively treats vascular lesions such as port-wine stains (birthmarks), salmon patches, hemangeiomas, lymphangiomas and other venous malformations, cherry angiomas, spider veins and varicose veins
  • treat mid to epidermal melasma
  • safely treat darker skin types
  • provide fractional laser rejuvenation on all skin types.
  • effectively treats rosacea 

Skin Conditions That Can Be Treated With Pro Yellow Laser?


The yellow light that comes from the laser is very helpful in treating acne, as it kills bacteria that cause it. This light also reduces the appearance of redness and inflammation simultaneously. Additionally, it also reduces the size of the sebaceous glands that are responsible for producing sebum.

Unsightly Veins

There is a high absorption rate in the red blood cells by PRO YELLOW laser compared to any other laser. As a result, it helps reduce the appearances of unsightly blood vessels and veins that are on the face. Particularly in areas like the nose and cheeks.


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

During laser treatment, laser energy is absorbed into the dermis layer of the skin, not only treating but also improving the support structure of the skin, resulting in the appearance of bright and firm skin. 


It has been found that the PRO YELLOW laser may reduce or eliminate the size of the blood vessels in the face and neck. Therefore, there will be less redness on the skin and a more even complexion. This laser may also reduce the redness on the skin caused by increased blood circulation, as it reduces the number of blood vessels in the area.

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.

Nevertheless, these side effects will disappear within a few hours of the treatment being administered.

How Many Sessions Do I Need?

It is possible to see visible results in a maximum of three treatments for vascular or pigmented lesions, spaced between 3 and 4 weeks apart. Thereafter, maintenance treatments are also required, and the amount of effective and visible results also depends on the severity of your skin condition. Nevertheless, it is also necessary to make sure that you get the right diagnosis of your skin condition as well as the right laser and treatment parameters.

However, topical anaesthesia will be prescribed to patients with low pain threshold in order to ensure a comfortable experience.

When Can I Expect To See Results?
