What should you know about Inkey List kojic acid?

Kojic acid is used in skincare to reduce the visible production of melanin, the pigment that contributes to brown marks. It may be considered when acne marks, sun-related spots, or general uneven tone are the concern. It does not treat every cause of skin darkening, and a product’s full ingredient list affects how your skin responds. Read more about [Kojic Acid](/materials/kojic-acid/) and have a persistent or changing mark checked.

Patch-test on a small area according to the product instructions before wider use. Start sparingly, apply to intact skin, and moisturise afterward if your skin feels dry. Wear broad-spectrum sunscreen during daylight; ultraviolet exposure can maintain or deepen uneven tone. Avoid adding multiple strong actives at once, since redness and inflammation can leave darker marks. A clinician can discuss whether a professional [Skin Brightening Treatment](/treatments/aesthetic-procedures/skin-brightening-treatment/) fits your skin type and diagnosis.

Stop using the product and seek medical advice for swelling, hives, blistering, intense burning, or a rash that continues after washing. Book a skin assessment for a mark that changes in colour, shape, or texture, or one that bleeds without clear injury. A professional review is also sensible when pigmentation keeps returning or does not respond to a gentle routine.

Ask whether kojic acid suits your diagnosis, how it should be combined with other actives, what irritation looks like, and when to stop or change the plan.
