What should you know about tranexamic acid for scars?

A healed cut, burn, spot, or procedure can leave a darker patch called post-inflammatory hyperpigmentation. Tranexamic acid targets processes involved in excess pigment formation, so any benefit is directed at colour rather than raised, indented, tight, or painful scar texture. A cream or serum is applied to the skin; oral treatment is a different decision and should not be started for a scar without medical supervision.

The area should be fully closed before applying a pigment treatment. Irritated skin can become darker, and sun exposure can keep the mark noticeable. Improvement, when it occurs, is gradual and varies with the cause and depth of the colour.

Have a dermatologist confirm that the mark is pigment rather than an active rash, infection, or another skin condition. Follow the product directions and introduce one new product at a time. Use gentle cleansing, moisturiser, and broad-spectrum sun protection on exposed skin. Stop and seek advice if burning, swelling, blistering, or a spreading rash develops. Do not put a topical product on an open wound, and do not substitute tablets intended for another condition.

Arrange a clinical review if a scar is growing, changing colour, bleeding, ulcerating, becoming increasingly painful, or limiting movement. Prompt care is also sensible for warmth, pus, fever, or rapidly spreading redness after an injury or procedure. A dark mark that changes unexpectedly deserves assessment before cosmetic treatment.

Ask whether the colour is post-inflammatory pigment, which formulation suits your skin, how long to try it, and what alternatives could address texture. Tell them about pregnancy, breastfeeding, allergies, sensitive skin, and every medicine or supplement you use.
