Hyperpigmentation is a common skin condition where patches of skin become darker in color than the surrounding skin. It can occur for various reasons and can affect people of all ages, genders, and skin types. In this comprehensive guide, we’ll break down everything you need to know about hyperpigmentation, from its types and causes to its symptoms, diagnostic tests, treatments, and preventive measures.

Types of Hyperpigmentation:

  20. Electrophoresis: Separates skin proteins for analysis.

Treatments for Hyperpigmentation:

  1. Sun Protection: Use sunscreen daily to prevent further darkening.
  2. Protective Clothing: Wear hats, sunglasses, and long sleeves to shield from UV rays.
  3. Avoid Irritants: Harsh chemicals and abrasive scrubs can worsen hyperpigmentation.
  4. Gentle Cleansing: Use mild, non-abrasive cleansers to avoid skin irritation.
