Pigment Lasers

In Singapore’s tropical climate, pigmentation issues like sunspots, melasma and post-inflammatory hyperpigmentation are especially common. Pigment lasers use specialised light wavelengths to break down unwanted pigmentation, improving skin tone with little to no downtime.

What is Pigment Laser treatment?

Pigment laser refers to a category of medical-grade lasers used to target and reduce skin pigmentation. These lasers are highly selective for melanin, which is the pigment responsible for dark spots. It is ideal for treating:

• Age spots
• Birthmarks
• Freckles
• Melasma
• Post-inflammatory hyperpigmentation (PIH)
• Sunspots (solar lentigines)
• Tattoos

How does Pigment Laser work?

The treatment uses light energy at specific wavelengths to target and break down unwanted pigment without harming the surrounding skin.

There are several types of lasers that can be used to treat pigmentation, each with its own benefits and applications. This includes:

• Fractional lasers – these lasers deliver tiny columns of energy into the skin to trigger a natural healing response. As the skin repairs itself, new collagen forms and helps to lighten pigmentation. They also refine skin texture and even out skin tone.
• Q-switched nanosecond laser – with very short, high-energy pulses of light, this laser technology breaks down excess melanin while sparing the surrounding skin. It is often chosen for deeper pigment conditions such as Hori’s nevus and Ota’s nevus. Modern Nd:YAG systems, like the MaQX platform, add flexibility by offering multiple wavelengths and fractional handpieces, enabling treatment at different skin depths while reducing unwanted heat build-up.
• Picosecond lasers – using ultra-fast pulses that are a thousand times shorter than nanoseconds, these lasers shatter pigment into very fine particles that the body can clear naturally. They are especially effective for freckles, sunspots, resistant pigmentation and even tattoos. The laser may also reduce the risk of PIH.

How does Pigment Laser remove pigmentation?

Treating pigmentation requires more than just power. It demands precision, safety and adaptability to different skin types. Modern pigment lasers are designed to target excess melanin effectively while minimising heat build-up. This reduces the risk of unwanted side effects such as PIH, especially in darker skin tones.

Different pigment lasers target pigmentation at varying skin depths. The following table will outline common wavelengths used, their applications and key considerations.

What are the benefits of Pigment Laser?

Pigment laser therapy offers effective pigment reduction with minimal downtime. This makes it suitable for a wide range of skin types, including Asian and darker skin tones.

Benefits include:

• Clinically proven results for pigment clearance
• Low risk of scarring when performed by dermatologists
• Safe for Asian skin types with proper settings
• Non-invasive and comfortable with optional topical anaesthesia
• Also improves skin tone and texture, offering a mild rejuvenating effect

What to expect when getting Pigment Laser treatment

The treatment can help you achieve clearer, more even-toned skin, without surgery or extended downtime. While the procedure is non-invasive and generally well-tolerated, knowing what to expect can give you the clarity and confidence to proceed with ease.

Consultation

Your journey starts with a detailed consultation. Our dermatologists will:

• Assess your skin type, type of pigmentation and overall condition
• Review your medical history and any past treatments
• Recommend a personalised treatment plan tailored to your skin needs and goals

This is important to ensure pigment laser is the right option for you, or whether another treatment may provide better results.

During the procedure

Once you are ready, your skin will be gently cleansed and prepped. A topical anaesthetic may be applied to ensure you are kept as comfortable as possible throughout the procedure.

You will be provided with protective eye shields throughout the session. You may feel a light prickling or snapping sensation as the laser pulses across your skin. Most patients find the treatment quick and tolerable. It typically lasts between 10 to 30 minutes, depending on the treatment area.

After the procedure

Most patients can return to daily activities straight after treatment, but understanding normal post-treatment changes helps you manage recovery and results.

• Temporary redness or swelling – mild redness or puffiness may occur and usually resolve within a few hours
• Pigment darkening – the treated spots may temporarily darken before naturally flaking off within 3 to 7 days on the face. This process may take longer on the arms or legs, depending on the area treated.
• Sun protection – wear SPF 50+ daily and avoid prolonged outdoor exposure
• Post-treatment skincare – use gentle products and avoid active ingredients like acids, retinoids or scrubs for a few days
• Healing support – moisturise regularly to soothe and protect the skin barrier as it recovers

What results can I expect?

Results vary based on the type and depth of pigmentation. Many patients notice visible lightening after 1 to 2 sessions, though a series of treatments spaced 4 to 6 weeks apart is often needed for gradual and sustained improvement.

With consistent treatment, you can expect:

• Reduction or clearance of targeted pigmentation
• A more even, radiant complexion
• Long-term skin clarity with appropriate skincare and sun protection

How many pigment laser sessions do I need?

The number of sessions depends on the type and depth of pigmentation, as well as how your skin responds. Generally, it takes: 

• Superficial spots – 1 to 3 sessions
• Melasma – 4 to 6 sessions, with maintenance once every few months 
• Deeper pigment or mixed types – 3 to 6 sessions or more
