Medicube TXA Niacinamide 15 Serum 30 ml

A lightweight brightening serum from Medicube with 10% niacinamide and 5% tranexamic acid (TXA), Medicube's highest TXA concentration, plus arbutin. The "15" in the name is the two actives combined. Medicube made it as an all-in-one serum for dark spots, acne marks, uneven tone and texture, with ten types of hyaluronic acid and panthenol to keep skin hydrated and calm.

How to use

1. After cleansing and toner, apply a few drops to the areas you want to treat, spreading wider as needed.
2. Pat in gently, then follow with moisturizer.
3. In the morning, always finish with sunscreen; dark spots fade faster when you protect them from the sun.

Cautions

For external use only. Avoid the eyes. Stop using it if irritation occurs. Medicube describes it as low-irritation and fragrance-free, but it contains rose flower oil, so patch test first if your skin is reactive. Store it in a cool, dry place away from sunlight, close the dropper tightly and use it within 12 months of opening. Keep out of reach of children.

Questions

Is the white powder around the bottle normal?
Yes. Medicube explains that the high niacinamide content can form a white residue around the opening; it doesn't affect quality. The colour may also fade with light exposure.

How is it different from the Anua Niacinamide 10 TXA 4 Serum?
Both pair niacinamide with tranexamic acid. Medicube's has 10% niacinamide with 5% TXA; Anua's has 10% niacinamide, 4% TXA and 2% arbutin. Pick one rather than layering both.

Can I use it with vitamin C or retinol?
Yes in most routines. If your skin feels irritated, use the vitamin C or retinol at a different time of day.

How long does delivery take in Egypt?
Delivery takes 3–7 business days, depending on your area.
