What should you know about kojic acid before and after?

Kojic acid is intended to influence excess pigment, not change your natural skin colour uniformly. The starting cause, depth of pigment, skin sensitivity, sun exposure, and product formula all affect visible change. Temporary dryness or mild tingling can occur, but increasing redness, scaling, or burning suggests that the barrier is struggling. A photograph can look different because of lighting, camera settings, makeup, or tanning, so comparisons should use similar conditions.

Before use, photograph the area in consistent light, read the ingredient list, and patch-test the product. Do not apply over a sunburn or immediately after an exfoliating procedure. During use, follow the label, moisturise, and protect the area from sunlight. If the skin becomes inflamed, stop until it settles and avoid chasing a quick result by increasing frequency. A professional skin-brightening treatment may be discussed when home care is insufficient.

Seek prompt advice for blistering, facial swelling, severe pain, or eye symptoms. Book a skin assessment if the mark enlarges, bleeds, develops an uneven border, or changes independently of the routine. Persistent darkening after irritation deserves review because inflammation itself can leave pigment.

Ask what improvement is realistic for your diagnosis, when to stop if irritation appears, and whether another treatment would address the underlying cause.
