What should you know about hyperpigmentation scars on legs?

A cut, scrape, insect bite, ingrown hair, acne-like bump, burn, or eczema flare can activate pigment-making cells. The skin may remain brown, grey-brown, or deeper in tone after the surface feels smooth. This is called post-inflammatory hyperpigmentation; it is a colour change rather than a raised scar. Repeated rubbing, picking, shaving irritation, and sunlight can keep the mark darker.

A clinician may examine the border, texture, scale, and the event that came before it. A persistent rough, bleeding, rapidly changing, or distinctly different spot needs a separate assessment rather than cosmetic treatment.

Protect exposed legs from sunlight with clothing or broad-spectrum sunscreen, and avoid scratching, harsh scrubs, and unprescribed bleaching products. Keep the skin moisturised and address the trigger, such as friction or recurring ingrown hairs. A dermatologist may discuss a prescribed topical medicine or an in-clinic option such as a chemical peel, IPL Photofacial, or picosecond laser treatment. These treatments require a plan suited to your skin tone because irritation can deepen pigment.

Arrange a dermatology review if a mark is enlarging, changing colour or shape, painful, itchy, scaly, crusted, or bleeding; if new spots keep appearing; or if the original wound is not healing. Seek prompt care for spreading redness, warmth, swelling, pus, fever, or significant pain around a recent injury.

Ask what caused the pigment, whether the texture represents a true scar, which ingredients are suitable for your skin tone, and how to reduce irritation during treatment. Ask how sun protection and treatment timing fit around shaving, waxing, or an active rash.
