Yellow Laser

옐로 레이저

What is Yellow laser?

Yellow Laser uses a specific wavelength of 577nm, designed to target vascular concerns, redness, acne-related inflammation, epidermal pigmentation, and overall skin rejuvenation.

Its technology works through selective absorption of light energy at 577nm, a wavelength closely aligned with the absorption peak of oxyhaemoglobin.

Often referred to as the “Korean Glass Skin Laser,” Yellow Laser is popular for its ability to improve skin clarity, reduce redness, and enhance radiance with minimal downtime when appropriately customised.

The Technology Broken Down

Targets redness and pigmentation with precision

At 577nm, the laser energy is selectively absorbed by haemoglobin in blood vessels and melanin in superficial pigmentation. This allows abnormal vessels and unwanted pigment to be gently heated and broken down while minimising impact on surrounding skin.

Optimised Wavelength Efficiency

Compared to traditional green lasers, the 577nm yellow wavelength achieves higher absorption in blood with less power required. This improves treatment uniformity and helps reduce the risk of excessive heat, making it suitable for a wider range of skin tones when properly assessed.

Skin Rejuvenation & “Glass Skin” Effect

Beyond treating redness and pigmentation, Yellow Laser stimulates collagen and elastin production in the superficial dermis. Over time, this supports smoother texture, refined pores, and a clearer, more luminous complexion.

What is the Treatment Process Like?

Step 1: Consultation & skin assessment

First, your skin will be gently cleansed before a skin analysis is conducted. A thorough consultation with a registered medical professional will be done prior to any treatment.

Step 2: Skin preparation

The skin is cleansed thoroughly. A topical numbing cream may be applied for comfort, as most patients tolerate the treatment well.

Step 3: Yellow Laser Treatment

The yellow laser is delivered to targeted areas using customised settings. Sensations are commonly described as mild warmth or tingling.

After the treatment, a soothing mask may be applied to calm the skin and reduce temporary redness.

Step 4: post-treatment care

A soothing mask may be applied after the treatment. Skincare and sun protection will also be applied, and aftercare instructions will be provided.

Step 5: review & maintenance

A treatment plan may include multiple sessions depending on the concern being treated.

Frequently asked questions

What does Yellow Laser treat?

Yellow Laser is commonly used to treat redness, rosacea, visible facial blood vessels, acne-related inflammation, post-acne redness, and superficial pigmentation. It is also used to improve overall skin clarity, tone, and radiance, making it popular for skin rejuvenation and “glass skin” protocols.

Yellow Laser operates at a 577nm wavelength, which is selectively absorbed by haemoglobin and superficial melanin. This allows it to target redness and vascular concerns more precisely while using lower energy levels compared to some other lasers, helping to reduce heat-related skin stress.

Most individuals describe the sensation as mild warmth, tingling, or light prickling. The treatment is generally well tolerated, and numbing cream is optional depending on individual comfort levels and treatment intensity.

Downtime is minimal. Some redness or flushing may occur immediately after treatment but usually subsides within a few hours. Most individuals are able to return to normal daily activities shortly after the session.

The number of sessions varies depending on the skin concern being treated, such as redness, pigmentation, or acne inflammation. Yellow Laser is usually recommended as a series of treatments, spaced a few weeks apart, to achieve gradual and sustained improvements.

Yellow Laser is commonly used to help manage rosacea-related redness and visible blood vessels. While it can significantly improve the appearance of redness, rosacea is a chronic condition and may require ongoing maintenance and lifestyle management.

Yes, Yellow Laser may help improve acne by reducing inflammation and redness associated with active breakouts. The 577nm wavelength can target acne-related vascular activity and support a calmer skin environment. It may also help reduce post-acne redness (PIE) and support overall skin recovery. For moderate to severe acne, Yellow Laser is often combined with other acne treatments as part of a customised plan.

A professional consultation is essential. Our aesthetic doctor will assess your skin condition, redness pattern, pigmentation type, and overall skin health to determine whether Yellow Laser is suitable or if alternative or combination treatments would be more appropriate.
