Medicube TXA Niacinamide 15 Serum, 30ml

This serum is made for:

• Dark spots: including flat marks left after a pimple heals.
• Acne scars
• Uneven skin tone: patches darker than the rest of your face.
• Texture: also a care step for texture.

It won’t clear active breakouts on its own, but it’s the treatment step of our Acne Kit.

This is your serum: after cleansing and toner, before moisturizer.

You can use it morning or night:

• In the morning: sunscreen is not optional.
• At night: it can be the main treatment step.

Using retinol or a strong acid? Add one new product at a time.

Tranexamic acid, often shortened to TXA, is the headline active here.

At 5%, it’s Medicube’s highest TXA concentration.

Only water, niacinamide, glycerin and butylene glycol come before it.

Alongside it is 10% niacinamide, a form of vitamin B3.

• Arbutin: the third key ingredient, right after TXA.
• Glutathione: appears further down.
• Hydration: a 10-layer hyaluronic acid complex.
• Panthenol and betaine: more hydration.
• Coral moss extract: helps calm and soothe.

With a fake serum, you can’t know what’s inside it or what it will do.

And in Nakuru, at about 1,850m, UV rises with altitude and can darken marks.

We sell only authentic Korean skincare, sourced from authorized distributors and wholesalers.

Dark spots usually start to look lighter after four to eight weeks of daily use.

Older or deeper marks can take longer, so keep going, with sunscreen every day.

Yes. The serum contains natural pigments and vitamin B12, which can fade with light. This doesn't affect how well it works.

It's niacinamide. At a high concentration, a light white powder can form where the serum meets air. It doesn't affect quality.

Use it within 12 months of opening. Close the dropper tightly and keep it somewhere cool and dry, out of direct sun.

Yes. UV exposure can darken marks left by breakouts, so daily sunscreen is part of fading them. Wear it every morning you use this serum.
