What should you know about kojic acid spot treatment?

Kojic acid is a topical ingredient used in products for uneven tone. Applied to a limited area, it is intended to act on excess pigment rather than change the colour of every part of the face. Dark marks can follow acne, irritation, inflammation, or sun exposure, so the reason for the mark still matters. A spot product cannot confirm its cause or replace an assessment of a changing lesion.

Follow the product directions and apply a thin layer to clean, dry skin. Keep it away from the eyes, lips, broken skin, and freshly irritated areas. Test a small area first if the product instructions allow it, and introduce it gradually rather than layering several strong brightening products at once. Use broad-spectrum sunscreen on exposed skin because ultraviolet light can deepen pigmentation and make progress harder to judge. Stop if burning, marked redness, swelling, or a spreading rash develops.

Arrange a medical review if a dark spot is new and changing, has an irregular border, bleeds, crusts, becomes painful, or does not behave like your other marks. Seek prompt care for facial swelling, blistering, or severe eye irritation after application. A dermatologist can distinguish pigmentation from conditions that need a different treatment.

Ask whether the mark is suitable for a topical brightening ingredient, how often to apply it, and which cleanser, moisturiser, or sunscreen can be used alongside it. Discuss alternatives if the area is sensitive or the pigmentation keeps returning.
