Kojic Acid + Vitamin C
Kojic Acid + Vitamin C — a brightening duo combining kojic acid, a fungal-derived ingredient that helps inhibit melanin production, with vitamin C, an antioxidant that supports radiance and collagen. The pair is often used to target dark spots, sun-related discoloration, and overall dullness.
Key points
- Kojic acid works by inhibiting tyrosinase, an enzyme central to melanin formation, which can help fade the look of discoloration.
- Vitamin C provides antioxidant protection and complements kojic acid by brightening tone and supporting skin structure.
- Combining the two can offer layered support for uneven tone, though kojic acid may be more prone to causing sensitivity in some people.
- Consistent sun protection is important, as both brightening results and pigmented skin are affected by UV exposure.

Is kojic acid irritating?
