Pico Laser Pigmentation Treatment | Medical Aesthetics 360 Laser Clinic

If you are searching for the best pigmentation laser in Sydney, or specifically looking for a laser clinic in Chatswood or Hurstville for pigmentation treatment, understanding how laser actually works is essential.

At Medical Aesthetics 360, we are a doctor-led Sydney laser clinic with locations in Chatswood and Hurstville, specialising in advanced pigmentation treatments using Pico laser, nano laser, long pulse laser and IPL technologies.

It is not the machine alone that determines results — it is the diagnosis, laser physics knowledge, wavelength selection and treatment planning.

Pigmentation treatment is not magic. It is medical science.

Why Pigmentation Requires Expertise (Not Just a Laser Machine)

Pigmentation is not one single condition. It may include:

• Freckles (ephelides)
• Solar lentigines (sun spots)
• Melasma
• Post-inflammatory hyperpigmentation (PIH) from acne or burns
• Hori’s naevus
• Becker’s naevus
• Mixed epidermal and dermal pigment

Each of these responds differently to laser.

Each requires:

• Different wavelengths
• Different energy parameters
• Different session numbers
• Different aftercare protocols

Inflammation by-product is pigment.

If inflammation continues — from acne, aggressive treatment, heat exposure, or poor aftercare — pigmentation can return darker.

This is especially relevant for patients with East Asian, Indian, and African skin types, who are more prone to PIH.

Understanding Laser Wavelengths: 1064 nm vs 755 nm vs 532 nm

At our Sydney pigmentation laser clinic in Chatswood and Hurstville, wavelength selection is based on depth, melanin absorption and skin type.

1064 nm (Nd:YAG) – Safer for Skin of Colour

Commonly used for:

• Dermal pigmentation
• Hori’s naevus
• Mixed-depth pigment
• PIH-prone skin
• East Asian, Indian and African skin types

1064 nm penetrates deeper and is less absorbed by surface melanin compared with shorter wavelengths. This makes it a preferred wavelength in many darker skin types to reduce surface overheating and minimise inflammation risk.

It may require more sessions — but prioritises safety and long-term stability.

755 nm (Alexandrite) – Strong Melanin Targeting

Best for:

• Brown spots
• Epidermal to mixed pigmentation
• Selected freckles and lentigines

755 nm has higher melanin absorption. It can deliver excellent pigment clearance but must be used carefully in:

• East Asian skin
• Indian skin
• PIH-prone individuals

Correct energy and spacing are critical to prevent rebound pigmentation.

532 nm – Superficial Pigment Treatment

Best suited for:

• Superficial freckles
• Surface sun spots
• Carefully selected lighter skin types

532 nm is strongly absorbed by melanin and works very superficially. While effective, it carries higher PIH risk in darker skin tones if not used cautiously.

Pico Laser vs Nano Laser vs Long Pulse Laser vs IPL in Sydney

Many patients in Sydney, Chatswood and Hurstville ask:

“Is Pico laser better for pigmentation?”

Pico Laser

• Picosecond pulse duration
• Efficient pigment fragmentation
• Useful in melasma and PIH-prone patients when applied conservatively

Nano Laser (Q-Switched)

• Nanosecond pulse duration
• Proven track record in pigment removal
• Effective when used appropriately

Long Pulse Laser

• Thermal-based approach
• Suitable for selected pigmented lesions

IPL (Intense Pulsed Light)

• Broad-spectrum light
• Effective for superficial sun damage and freckles
• Operator-dependent and not suitable for all pigmentation types

Excellent IPL can work.
Nano lasers can work.
Long pulse lasers can work.
Pico lasers can work.

The key factor is not the modality — it is the understanding of laser physics, skin biology and inflammation control.

Pigmentation Treatment in Different Skin Types

East Asian Skin

• High PIH risk
• Melasma common
• Heat-sensitive

Approach: Conservative treatment parameters, inflammation control, structured aftercare.

Indian / South Asian Skin

• Strong PIH tendency
• Acne-related pigmentation common

Approach: Gradual staged treatments, careful wavelength selection.

Caucasian Skin

• Freckles and sun spots common

Approach: Target superficial lesions appropriately and maintain prevention plan.

African Skin

• High melanin density
• Higher PIH and hypopigmentation risk

Approach: Conservative energies, longer timeline, precise planning.

Different Conditions Require Different Session Numbers

Freckles

Often respond quickly but recur with sun exposure.

Melasma

Chronic and trigger-driven. Requires long-term management.

PIH (Acne / Burns)

Pigment is a reaction. Treat inflammation, not just pigment.

Hori’s Naevus

Dermal pigment. Typically requires multiple sessions.

Becker’s Naevus

Complex lesion. Response varies.

This is where doctor diagnosis and personalised treatment planning make the difference.

Aftercare: Essential for Long-Term Results

Laser is not magic. Aftercare protects your results.

Because inflammation fuels pigmentation, post-treatment care includes:

• Daily broad-spectrum sun protection
• Avoiding excessive heat exposure
• Gentle skincare and barrier repair
• Avoiding picking or friction
• Managing active acne

Poor aftercare is a common reason pigmentation returns.
