Struggling with dark spots, uneven patches and post-blemish marks that just won't shift? The Medicube Kojic Acid Turmeric Capsule Serum targets the root of discolouration with a triple brightening approach — Kojic Acid, Turmeric and Niacinamide — delivered through a next-generation capsule technology that releases actives on contact for faster, more effective results.
The standout feature of this serum is its Glow Capsules — snowflake-like micro-capsules visible in the formula that burst on application, instantly releasing Squalane and Thioctic Acid (Alpha-Lipoic Acid) directly onto the skin. This targeted delivery not only boosts absorption of the actives but provides an immediate hit of barrier-repairing moisture and antioxidant protection right at the skin's surface.
Kojic Acid — derived from fungi and fermented grains — is one of the most well-established skin-brightening ingredients available, working by inhibiting tyrosinase, the enzyme responsible for melanin production. This directly fades the appearance of dark spots, post-acne marks and uneven patches. Curcuma Longa (Turmeric) Root Extract, rich in the antioxidant compound curcumin, soothes inflammation, calms stressed and blemish-prone skin, and protects against oxidative damage — making it the ideal pairing with Kojic Acid for skin that needs both brightening and calming. Niacinamide refines texture, supports the moisture barrier and further evens skin tone. Tocopherol (Vitamin E) adds antioxidant depth. Glycolic Acid provides gentle surface exfoliation to improve texture and enhance penetration of the brightening actives.
The formula is rounded out with a supporting botanical complex of Neem (Melia Azadirachta Leaf and Flower Extract), Holy Basil (Ocimum Sanctum), Ivy Gourd (Coccinia Indica) and Eclipta Prostrata — all well-regarded in dermatological tradition for their anti-inflammatory and antimicrobial properties — alongside Allantoin and Panthenol for soothing and repair, Adenosine for anti-ageing support and Corallina Officinalis (Red Algae) for mineral-rich barrier care. Chamaecyparis Obtusa (Hinoki Cypress) Wood Oil provides antiseptic and calming properties.
How To Use
After cleansing and toning, apply a few drops to the face. Gently press and pat into the skin — do not rub, to preserve the Glow Capsules and maximise release on contact. Use morning and/or evening. If using in the morning, always follow with SPF 30+. If using Glycolic Acid or other exfoliants elsewhere in your routine, avoid layering them on top.

Clinically tested: suitable for all skin types including sensitive and acne-prone skin
Skin Type
All skin types including sensitive and acne-prone. Clinically tested by the Global Institute of Dermatological Sciences. Contains Glycolic Acid — those with very reactive or rosacea-prone skin should patch test and introduce gradually.
Pregnancy: Contains Kojic Acid and Glycolic Acid. Both are used in cosmetics and are not broadly restricted, but consult your GP or midwife before use during pregnancy or breastfeeding.
What are the Glow Capsules?
They are the snowflake-like micro-capsules you can see floating in the serum. They contain Squalane and Thioctic Acid (Alpha-Lipoic Acid) and burst on contact with the skin, releasing these actives directly at the surface for instant hydration, barrier support and antioxidant protection.
Does it work on post-acne marks?
Yes — Kojic Acid specifically targets post-inflammatory hyperpigmentation (the dark marks left after blemishes heal) by blocking the melanin production process. Turmeric's anti-inflammatory action and Glycolic Acid's exfoliating effect work alongside it to accelerate the fading process.
Can I use it with other brightening actives like Vitamin C or AHAs?
It already contains Glycolic Acid, so avoid layering additional AHA or BHA exfoliants in the same step to prevent over-exfoliation. If you use a Vitamin C serum, use it at a different time of day or on alternating days.
Do I need to use SPF?
Yes, always — particularly when using a serum containing Kojic Acid and Glycolic Acid, which can increase photosensitivity. Apply SPF 30+ every morning without exception.
Is it suitable for sensitive skin?
Yes — it is clinically tested for all skin types including sensitive skin. If your skin is very reactive, patch test first and introduce every other evening before building to daily use.
Is it pregnancy-safe?
It contains Kojic Acid and Glycolic Acid. Neither is broadly restricted, but consult your GP or midwife before use during pregnancy or breastfeeding.
