Pigmentation and Dark Spots: Causes and Dermatological Treatment

Published on May 25, 20261 min read • By Dr. Umesh Thombe

What Causes Hyperpigmentation?

Hyperpigmentation occurs when specialized cells in the skin called melanocytes produce too much melanin—the pigment that gives skin its color. Common types include:

  • Melasma: Symmetrical, dark brown patches on the cheeks and forehead, often triggered by UV exposure and hormonal shifts.
  • Post-Inflammatory Hyperpigmentation (PIH): Dark spots left behind after acne blemishes or skin injuries heal.
  • Sun Spots (Solar Lentigines): Flat brown spots caused by long-term UV exposure.

Dermatological Treatments

  1. Medical Topicals: Tyrosinase inhibitors containing Kojic Acid, Azelaic Acid, or Arbutin to control melanin production.
  2. Targeted Chemical Peels: Graded peels to exfoliate pigmented skin cells quickly.
  3. Q-Switched Nd:YAG Lasers: Advanced lasers that target and shatter pigment deep within the skin, allowing the body to clear it naturally.
