Mizu’s Yellow laser delivers a specific wavelength of 577nm that is that is designed for the treatment of vascular conditions and epidermal pigmentation.
The yellow laser is sometimes referred to as the “glass skin laser” due to its ability to help achieve bright, glowy skin. Additionally, the yellow laser can help reduce pigmentation and redness, treat acne conditions, and reduce red facial veins.
The main difference between the yellow laser and other skin rejuvenation lasers is its specific wavelength. The yellow laser operates at a wavelength of 577nm, unlike predecessors that use a mixture of 532nm (green) and 577nm (yellow) wavelengths.
The specific wavelength of 577nm means that the yellow laser can be used to safely treat various conditions such as pigmentation, rosacea, red acne marks, and uneven skin tone. The 532nm wavelength is believed to leave Asian skin more susceptible to hyperpigmentation.
“The majority of visible unwanted skin spots, discolourations, or redness (blood vessels) are rooted in a deeper vascular network of veins that extend beyond the treatable depth of traditional green (532nm) lasers. Not addressing these areas can result in recurrence and the inability to effectively treat deeper pigmented and vascular issues.”
The yellow laser, by reducing vascular conditions (blood vessels and redness), helps prevent pigmentation and prolong the results after pigmentation clearance.
The 577nm wavelength of the yellow laser is effectively absorbed by both melanin (pigmentation) and oxyhaemoglobin (blood vessels), as shown by the laser absorption graph.
Therefore, the yellow laser can treat pigmentation issues and conditions that cause redness, such as facial veins, rosacea, and acne.
It is used for treating:
Pigmentation
Vascular Conditions
Acne
Skin Brightening

Where possible, pigmentation problems should be treated using a multi-modal approach. This involves combining treatments such as topical creams, medication, and different lasers for effective results.
This is because most pigmentation problems involve different types of pigmentation, each requiring different laser settings.
Freckles
Age Spots
Sun Spots
Melasma (epidermal type)
Café au lait birthmarks
The energy from the yellow laser is absorbed by both melanin (pigments) and underlying blood vessels. This results in the breakdown of pigments and a reduction in the blood supply to the skin cells that produce these pigments. This potentially prevents these skin cells from producing pigments, ensuring longer-lasting results.
Vascular conditions cause redness and flushing on the face due to the dilation of small superficial blood vessels in the skin. They can appear as red spots or visible threads on the skin.
The yellow laser can treat vascular conditions such as:
Facial/nose veins and blood vessels
Redness and Rosacea
Cherry angiomas, Telangiectasia, etc.
The yellow light energy from the yellow laser targets acne caused by P. acne bacteria by reducing these bacteria. It also helps reduce redness caused by inflammation and shrinks sebaceous glands that produce sebum (oil).
Red acne marks, also known as PIE (Post-inflammatory Erythema), form due to increased blood circulation at badly inflamed acne sites. These marks are redness that persists even after the acne heals. The yellow laser can help reduce these red marks by targeting the blood vessels in these areas.
‘Glass Skin’ is a term popularised by Korean doctors and celebrities.
It was coined as ‘glass skin’ because the treatment achieves a glow that makes the skin look smooth and bright. The yellow laser is a treatment that can help achieve the ‘glass skin’ effect.
The yellow laser achieves the ‘glass skin’ effect by:
Brightening the skin due to the yellow light energy
Absorbing heat energy into the skin dermis and improving the skin’s collagen structure
Reducing redness for an even skin tone
Reducing imperfections such as pigmentation
For pigmentation treatment, some pigments may appear darker initially right after the treatment. This is the ‘end point’ that doctors aim for to remove the pigments effectively. This slight darkening of the pigments usually lasts 3-7 days and is not very noticeable. In some cases, such as freckles or sun spots, some scabbing might occur to remove the pigments. The scabbing typically falls off after 3-4 days.
For the removal of red veins and red acne marks, flushed skin can be expected due to the heat. Flushing typically lasts from 2 to 24 hours and gradually subsides.
‘Glass skin’ protocols usually have no downtime except for slight pinkish skin for 15-30 minutes.
Avoid strong sun exposure for at least 1 week both BEFORE and AFTER the yellow laser. Avoid scrubbing and exfoliation for 1 week after the procedure if there is any scabbing.
