Brown spots, melasma, sun damage, and uneven skin tone are among the most common concerns we treat at MD Laser & Cosmetics. The good news: hyperpigmentation is highly treatable with the right medical approach — and the right approach depends on what is causing it.

What causes hyperpigmentation?

Hyperpigmentation happens when the skin produces excess melanin in concentrated areas. Common triggers include:

  • Sun exposure — the leading cause of brown spots and “age spots,” especially in our California climate
  • Melasma — hormone-related patches, often triggered by pregnancy or birth control
  • Post-inflammatory pigmentation — marks left after acne, injury, or irritation
  • Natural aging — cumulative sun and cellular changes over time

Because the causes differ, a treatment that works beautifully for sun spots may worsen melasma. This is why a physician evaluation matters before starting any treatment.

Physician-led treatments for uneven skin tone

At MD Laser & Cosmetics in San Mateo, Dr. Susan Lin tailors treatment to your skin type and the source of your pigmentation:

  • IPL Photofacial — targets sun damage and brown spots, helping reveal brighter, more even-toned skin. IPL photofacial starts at $500.
  • Medical-grade chemical peels — resurface and lift pigmentation at controlled depths.
  • Prescription-strength topical regimens — physician-selected products to suppress excess melanin safely.
  • Combination plans — for stubborn melasma, a layered, conservative approach often works best.

Why skin type matters for safety

Treating pigmentation on deeper skin tones requires extra care — the wrong laser settings can actually trigger more pigmentation. Dr. Lin’s physician training and adjustable, medical-grade technology allow safe, effective treatment across a range of skin tones.

Protecting your results

Any pigmentation treatment is only as durable as your sun protection. Daily SPF and a physician-guided maintenance plan keep results from reversing. Dr. Lin will build this into your plan.
