The Medicube Kojic Acid Turmeric Niacinamide Serum is a clarifying, brightening serum formulated to visibly improve uneven skin tone, refine the appearance of skin texture, and support the skin's natural moisture barrier. The formula combines three hero actives — Kojic Acid, Curcuma Longa (Turmeric) Root Extract, and Niacinamide — with a unique delivery system of snowflake-like micro-capsules containing Squalane and Thioctic Acid (Alpha Lipoic Acid), which burst on contact with skin to release hydration and support the barrier. Clinically tested and suitable for all skin types including delicate skin. Dermatologist-tested by the Global Institute of Dermatological Sciences. 100% made in Korea.
Key Benefits
- Visibly brightens and evens skin tone — Kojic Acid and Niacinamide work together to help reduce the visible appearance of uneven patches, dark spots, and post-blemish marks for a more balanced-looking complexion
- Soothes and visibly calms the skin — antioxidant-rich Turmeric (Curcuma Longa) Extract helps soothe the appearance of stressed, uneven skin while contributing antioxidant protection against environmental aggressors
- Unique snowflake micro-capsule delivery system — visible snowflake-like capsules burst on contact with skin, releasing Squalane and Thioctic Acid (Alpha Lipoic Acid) to support the moisture barrier and boost absorption of active ingredients
- Supports the skin's moisture barrier — Squalane, Panthenol, and Jojoba Esters help replenish and maintain the skin's natural barrier for a visibly smoother, more comfortable complexion
- Refines the visible appearance of skin texture — Glycolic Acid (AHA) gently encourages surface cell turnover, helping to smooth the visible appearance of rough or uneven skin texture over time
- Visibly firms and supports elasticity — Adenosine supports the visible appearance of skin firmness and helps soften the look of fine lines over time
- Antioxidant protection — Tocopherol (Vitamin E) and Turmeric Extract provide antioxidant coverage to help protect the skin's appearance from the visible effects of daily environmental stressors

How to Use
- After cleansing and toning, dispense a small amount onto clean fingertips.
- Gently smooth over the face, pressing lightly to encourage the micro-capsules to burst and release the active ingredients.
- Allow to absorb fully before applying your moisturiser.
- Can be used morning and evening. If using in the morning, always follow with a broad-spectrum SPF — particularly important when using AHA-containing products such as Glycolic Acid.
- If new to Glycolic Acid, begin by using every other evening and increase frequency gradually as your skin builds tolerance.
Key Ingredients
- Kojic Acid — derived from fungi and fermentation processes, Kojic Acid works to visibly improve the appearance of uneven skin tone and dark spots by inhibiting the visible formation of excess pigmentation. Helps the complexion appear more even, brighter, and balanced over time.
- Curcuma Longa (Turmeric) Root Extract — a potent antioxidant botanical rich in curcumin. In skincare, Turmeric Extract helps protect the skin from the visible effects of environmental stressors and free radical damage, while also contributing to a visibly brighter, more even-toned appearance. Its antioxidant and soothing properties make it a well-suited companion for brightening actives.
- Niacinamide (Vitamin B3) — one of skincare's most well-researched multi-tasking actives. Works to visibly brighten uneven skin tone, reduce the appearance of post-blemish marks, minimise the visible size of pores, smooth skin texture, and provide lightweight hydration. Supports the skin's natural moisture barrier and helps the complexion appear more even and refined.
- Squalane (in Micro-Capsules) — a lightweight, skin-compatible emollient derived from plant sources. Squalane helps soften and condition the skin without congesting pores, leaving a smooth, comfortable finish. Delivered via the formula's signature snowflake micro-capsules for enhanced absorption.
- Thioctic Acid / Alpha Lipoic Acid (in Micro-Capsules) — a potent, water- and oil-soluble antioxidant that helps protect the skin from the visible effects of free radical damage. Also delivered via the snowflake micro-capsules to support absorption alongside Squalane.
- Glycolic Acid (AHA) — an alpha hydroxy acid that gently encourages surface-level exfoliation to help smooth the visible appearance of uneven skin texture, refine pore appearance, and improve the skin's overall radiance and clarity over time.
- Adenosine — a cell-communicating ingredient that supports the visible appearance of skin firmness and helps soften the look of fine lines, contributing to a smoother, more youthful-looking complexion over time.
- Panthenol (Provitamin B5) — a skin-compatible humectant and soothing ingredient that helps maintain the skin's moisture levels and support a calm, comfortable skin appearance alongside active brightening ingredients.
- Tocopherol (Vitamin E) — a well-established antioxidant that complements the formula's brightening actives by helping to protect the skin from the visible effects of environmental aggressors and free radical damage.
- Allantoin — a soothing ingredient that helps support a calm, comfortable skin appearance, particularly valuable in formulas containing exfoliating actives like Glycolic Acid.
- Jojoba Esters — wax esters derived from Jojoba that provide a smooth, silky skin feel while contributing mild emollient conditioning to leave the skin feeling soft and comfortable after application.
