Introduction to Yellow Laser and Its Use in Skin Rejuvenation

The yellow laser, also known as the glass skin laser, is a skin rejuvenation technology that uses a specific wavelength of 577nm. It is a non-invasive procedure designed to treat various skin concerns, including pigmentation, redness and rosacea, acne-related marks, and uneven skin tone.

​

Yellow laser treatment has become a option for patients seeking non-ablative laser procedures for clearer, brighter skin. The Pro Yellow Laser, a branded variant of the yellow laser, offers a targeted wavelength that is absorbed by melanin and blood vessels, helping manage both pigmentation and vascular conditions.

How Does the Yellow Laser Work?

The wavelength of 577nm is significant because it provides effective absorption by oxyhemoglobin and melanin. Compared to the older mixture of 532nm green and yellow light, the Pro Yellow Laser uses 577nm pure yellow light, minimizing the risk of post-inflammatory pigmentation, especially in Asian skin types.

​

This laser is absorbed by melanin and also by the blood vessels, making it suitable for addressing multiple skin concerns in a single session. The energy targets both superficial pigmentation and deeper vascular structures, breaking down melanin clusters and shrinking dilated blood vessels.

Skin Concerns Treated by Yellow Laser

The yellow laser can be used to manage multiple skin conditions, such as

​

  • Freckles

  • Sun spots

  • Melasma (epidermal type)

  • Redness and rosacea

  • Acne scars and post-inflammatory erythema

  • Uneven skin tone

​

For vascular-related issues, yellow laser is a choice for its ability to target facial veins and small capillaries. It is also effective for treating cherry angiomas, telangiectasia, and mild vascular conditions found on the face.

Mechanism of Action in Acne and Pigmentation Treatment

In acne management, Pro Yellow Laser treatment focuses on reducing acne-causing bacteria (Propionibacterium acnes) through selective photothermal action. The yellow light energy penetrates the skin and targets acne-associated bacteria, reduce inflammation, and shrink oil glands.

​

For pigmentation and redness, the laser is able to break down pigmented lesions and decrease the vascular component contributing to redness. Over time, the treatment can result in a reduced pigmentation appearance

​

The laser also stimulates collagen production, which supports skin rejuvenation by improving elasticity and texture.

Procedure and Treatment Sessions

Laser treatment with the Pro Yellow Laser typically lasts 30 to 45 minutes per session. Most patients tolerate the procedure well, with only mild discomfort described as a warm or prickling sensation. Topical anesthesia may be used depending on sensitivity.

​

The number of sessions required varies based on skin condition severity. On average, a course of six sessions spaced three weeks apart is recommended. Maintenance sessions may be advised for long-term results.

Safety and Side Effects

Laser treatments using yellow light are generally considered safe for all skin types. However, as with any procedure, there are side effects such as:

​

  • Temporary redness and swelling

  • Mild discomfort or tingling

  • Rare cases of blistering or hyperpigmentation

​

These effects typically resolve within hours to a few days. Following the procedure, patients are advised to avoid sun exposure and refrain from using exfoliants or retinoids for about a week.

Expected Results and Recovery

Results are cumulative. After multiple laser treatments, improvements are seen in the skin’s tone, clarity, and texture. Yellow laser treatment may contribute to dermal repair processes by encouraging collagen production and improving the dermal matrix.

​

In the case of pigmentation or vascular issues, results may include the fading of freckles, sun spots, and vascular lesions. For acne, it helps reduce breakouts and improve post-acne discoloration. The outcome is a more even skin tone may be observed often referred to as the glass skin effect.
