What Is Kojic Acid?

Kojic acid is a natural compound derived from the fermentation of rice or certain fungi. Traditionally used in Japanese skincare, it has become a go-to ingredient for treating hyperpigmentation, melasma, and age spots. Its main mechanism is inhibiting tyrosinase, an enzyme responsible for melanin production.

Why They Work So Well Together

When combined, Kojic Acid and Niacinamide target multiple layers of skin health:

1. Brightening from Two Angles – Kojic acid reduces melanin production, while niacinamide prevents uneven pigment transfer.
2. Balancing Irritation – Niacinamide’s calming properties offset the mild exfoliating effect of kojic acid.
3. Boosting Hydration – Niacinamide keeps the skin barrier strong, ensuring moisture retention.

How to Incorporate Them into Your Routine

• Use a serum with both ingredients in the morning and/or evening.
• Apply sunscreen daily, as brightening actives make skin more sensitive to UV rays.
• Start with lower concentrations to minimize the risk of irritation.
