Kojic Acid for Pigmentation

Pigmentation is a visible change in skin colour caused by extra melanin or uneven distribution of pigment. It can follow acne, eczema, an injury, hormonal shifts, sun exposure, or irritation from a product. Because several conditions look similar, a new or unusual patch should not be assumed to be simple pigmentation.

Kojic acid acts on pigment production in the skin where it is applied. It may help the colour blend more closely with nearby skin, but it cannot correct an ongoing trigger such as friction, inflammation, or repeated daylight exposure.

Use a suitable formulation on clean, dry skin according to its label or a clinician's instructions. Begin gradually, moisturise regularly, and avoid applying it to broken, sunburned, or actively irritated skin. Combining many exfoliants or pigment products can increase stinging and peeling.

Protect exposed areas with broad-spectrum sun protection and shade. If the patch darkens after starting, pause the product and ask for advice; irritation can make uneven colour more noticeable. A clinician may recommend a different ingredient or procedure after identifying the cause. Explore [Kojic Acid](/materials/kojic-acid/) and [Skin Brightening Treatment](/treatments/aesthetic-procedures/skin-brightening-treatment/).

Arrange an assessment for a patch that changes quickly, has an uneven border, bleeds, crusts, hurts, ulcerates, or differs sharply from your other marks. Get help for swelling, blistering, or intense burning after application.

Ask what caused the pigmentation, whether the product is appropriate for your skin tone and body area, how long to trial it, which products to avoid alongside it, and how to protect the result from renewed darkening.
