Laser and Medical Treatments for Dark Spots, Melasma and Uneven Skin Tone

Skin pigmentation concerns such as dark spots, melasma, and uneven skin tone are common, particularly in all skin types. These can be triggered by sun exposure, hormonal changes, inflammation, and ageing.

At Stephanie Ho Dermatology, we provide comprehensive pigmentation treatment, combining medical skincare, oral therapy, and advanced laser treatments for safe and effective results.

Understanding skin pigmentation

Pigmentation can occur at different stages of life:

  • At birth: café-au-lait spots, naevus of Ota
  • Childhood / adolescence: freckles, Becker's naevus
  • Adulthood: melasma, sun spots (freckles, solar lentigines), Hori's naevus

Accurate diagnosis is essential, as some conditions—particularly melasma—can worsen with inappropriate or overly aggressive laser treatment.

Treatment approach for pigmentation

Effective pigmentation treatment requires a multi-layered approach, not just lasers.

1. Sun protection (essential foundation)

Daily sun protection is critical for both treatment and prevention.

  • use broad-spectrum SPF 50+ sunscreen
  • reapply regularly
  • wear hats, sleeves and sunglasses

UV exposure stimulates melanin production and worsens pigmentation.

Oral antioxidants such as Polypodium leucotomos may provide additional protection against UV-induced pigmentation.

2. Medical-grade lightening creams

Topical treatments help reduce pigmentation safely and effectively. Common ingredients include:

  • hydroquinone
  • azelaic acid
  • kojic acid
  • arbutin
  • retinoids (e.g. tretinoin) to increase cell turnover

For sensitive skin or long-term use:

  • cysteamine
  • tranexamic acid creams

These treatments:

  • inhibit melanin production
  • gradually lighten dark spots
  • improve overall skin tone

3. Oral treatments for pigmentation

Oral therapies may be used for conditions such as melasma.

  • Oral tranexamic acid
    • reduces pigment stimulation pathways
    • effective for melasma when used under supervision
  • Glutathione
    • antioxidant support
    • may improve overall skin brightness

These are typically used as part of a combined treatment plan.

4. Laser treatments for pigmentation

Laser treatments are used to target deeper or more stubborn pigmentation. We offer a range of advanced pigment lasers, including:

  • picosecond lasers
  • Q-switched Nd:YAG lasers
  • long pulsed Alexandrite lasers
  • dual wavelength lasers

These lasers work by:

  • breaking down pigment into smaller particles
  • allowing the body to clear pigmentation naturally

Treatment approaches

Gentle laser treatments (no downtime)

  • gradual lightening
  • suitable for maintenance and busy lifestyles

Stronger laser treatments

  • faster results
  • may involve short downtime

Treatment choice depends on:

  • type of pigmentation
  • skin type
  • risk of post-inflammatory hyperpigmentation
Gentle laser treatments with no downtime and gradual lightening compared with stronger laser treatments giving faster results but possible short downtime

5. Combination treatments for optimal results

Many patients benefit from combining:

  • pigment lasers
  • medical skincare
  • skin rejuvenation treatments

Combination approaches help:

  • improve pigmentation
  • enhance skin texture
  • reduce pore size and fine lines

Important considerations

  • sun protection is essential before and after treatment
  • multiple sessions are often required
  • results are gradual and improve over time

Your dermatologist will discuss:

  • expected outcomes
  • number of sessions required
  • risks such as post-inflammatory hyperpigmentation

Pigmentation treatment is complex, especially in all skin types.

  • your dermatologist selects and performs all your treatments
  • treatments are tailored to your skin type
  • appropriate lasers and settings are selected carefully
