Ingredient overview

What is Kojic Acid?

Kojic acid is a fermentation-derived compound used in pigmentation-focused skincare because it can inhibit tyrosinase, an enzyme involved in melanin production. Kojic dipalmitate is a related derivative that is more oil-soluble and stable but is not identical to kojic acid in evidence or activity.

Kojic acid appears in products for melasma, dark spots and post-inflammatory hyperpigmentation, often alongside other brightening ingredients. Clinical evidence supports a role in hyperpigmentation regimens, but irritation and sensitization can limit use in reactive skin.

Routine guidance

How to use it

Use kojic-acid products according to directions and introduce gradually if you are sensitive. Sunscreen is essential in any dark-spot routine.

Pairing guidance

Routine compatibility

Kojic acid can be combined with niacinamide, tranexamic acid, alpha-arbutin and vitamin C, but stacking several strong brighteners may increase irritation.

Formula context matters

Good to know

Kojic acid can cause irritation or allergic contact dermatitis in some users. Kojic dipalmitate should not be assumed to have the same potency or evidence.
