What should you know about brown hyperpigmentation?

Pigment may increase after acne, eczema, an injury, or irritation from a product. Sun exposure can deepen existing marks and contribute to broader dark patches. Hormonal changes and some medicines can also influence pigmentation. The shade, border, surface, location, and timing help a clinician separate a flat pigment change from a mole, rash, or another lesion. The underlying trigger matters because pigment can return if ongoing inflammation or sun exposure is not addressed.

Use daily broad-spectrum sunscreen and protective clothing, and choose gentle, fragrance-free skin care. Treat active acne or dermatitis rather than repeatedly irritating the mark. A dermatologist may discuss Hydroquinone Treatment, a Chemical Peel, or Skin Brightening Treatment; selected pigment marks may be considered for IPL Photofacial or Picosecond Laser Treatment. These options need personalised selection because irritation can make pigmentation darker, particularly in deeper skin tones.

Seek assessment for a new or rapidly changing patch, an irregular edge, multiple colours, bleeding, crusting, pain, or a raised surface. Arrange review when pigmentation follows a new medicine or comes with widespread rash or other symptoms. A stable, flat mark can still be assessed if it is persistent or troubling you.

What triggered this pigmentation, and is that trigger still active? Is the pigment superficial or deeper? Which treatment is least likely to irritate my skin, and how will progress be monitored?
