What should you know about freckles on knees?

Knee skin is exposed to rubbing from clothing, kneeling and dry-skin irritation. Inflammation or a healed scrape can leave extra pigment that resembles a freckle. True freckles can darken with sunlight, while a single new mark may be another type of mole or pigmented lesion.

Moisturise regularly, avoid abrasive scrubbing and reduce repeated pressure when possible. Use sunscreen on exposed knees. A dermatologist can confirm the diagnosis before discussing IPL Photofacial or Picosecond Laser Treatment. Do not use strong acids without guidance.

Arrange an examination for a mark that changes in size, shape or colour, develops an irregular border, bleeds, crusts, becomes painful or remains itchy. A rapidly evolving or noticeably different spot should be assessed promptly.

Ask whether the mark is a freckle, post-inflammatory pigment or a mole, whether treatment is appropriate, and how to prevent friction and irritation during recovery.
