Collection: Kojic Acid

Kojic acid is a brightening ingredient derived from fermented Asian mushrooms and rice, used for decades in Korean and Japanese skincare to fade dark spots, melasma and uneven tone. It works by inhibiting tyrosinase, the enzyme responsible for melanin production, which means it addresses the cause of pigmentation rather than just masking it. Used consistently over several weeks, it delivers visible brightening with less irritation risk than stronger alternatives.

The Medicube Kojic Acid Turmeric range covers a complete routine, with the Vita Capsule Cream and Turmeric Pad as the daily-use anchors. The Nineless B-Boost 1% Kojic Acid Serum is the targeted treatment for stubborn dark spots, and the Nineless B-Boost 1% Kojic Acid Toner layers kojic acid into the hydration step. The Medicube Kojic Acid Turmeric Niacinamide Serum pairs kojic acid with niacinamide for layered brightening. Stocked and dispatched from our UK warehouse with free delivery on orders over £22.
