Is Medicube TXA Niacinamide Serum right for your skin?
Best for
- Post-acne marks and dark spots that linger after breakouts
- Dull or uneven-looking tone, especially on skin that gets a lot of sun
- Oily and combination skin that wants a light serum, not a heavy cream
Skip it, or patch-test first, if
- Your skin flushes or stings with niacinamide: start every other day, or patch-test on the jawline first
- You have melasma or patchy pigmentation that keeps returning: a dermatologist can tell you which options suit your skin
- You will not wear sunscreen every morning: brightening serums do little without it
How do you use Medicube TXA Niacinamide Serum?
Morning
- Cleanse and apply toner.
- Press 2–3 drops over the face, or focus on areas with dark spots.
- Follow with moisturiser and a broad-spectrum SPF 50 sunscreen.
Evening
- Double cleanse if you wore sunscreen or makeup.
- Apply 2–3 drops after toner and let it absorb.
- Seal with a moisturiser such as Medicube TXA Niacinamide Capsule Cream.
Sensitive skin: start with evening use only for two weeks. Dark spots fade slowly, so give it several weeks of daily use and sunscreen.
What are the key ingredients in Medicube TXA Niacinamide Serum?
- Tranexamic acid (TXA) — a brightening ingredient used for stubborn dark spots and uneven-looking tone; it works well alongside niacinamide
- Niacinamide (vitamin B3) — helps the tone look more even, supports the skin barrier and helps pores and oiliness look more balanced
- Adenosine — a skin-conditioning ingredient used in Korean skincare to help skin look smoother
Medicube TXA Niacinamide Serum vs Anua Niacinamide + TXA Serum: which should you choose?
| Medicube TXA Niacinamide Serum | Anua Niacinamide + TXA Serum | |
|---|---|---|
| Format | Brightening serum, 30ml | Brightening serum |
| Key ingredients | Tranexamic acid and niacinamide | Niacinamide 10% and tranexamic acid 4% |
| Main focus | Dark spots and uneven-looking tone | Post-acne marks, dark spots and uneven-looking tone |
| Step in the routine | After toner, before moisturiser | After toner, before moisturiser |
Both pair tranexamic acid with niacinamide. Choose the Medicube serum if you already use Medicube and want to pair it with the matching TXA Niacinamide Capsule Cream. Choose the Anua serum if you want a formula that states its niacinamide and TXA percentages on the label. Use one of them, not both, and wear sunscreen every morning.
How can you tell if your Medicube TXA Niacinamide Serum is original?
- The serum should be smooth and evenly mixed, with no separation, lumps or sour smell.
- The box should be sealed, with the full product name, ingredient list and Medicube details printed clearly; blurred printing or spelling mistakes suggest a copy.
- A price far below other trusted sellers usually means old stock or a fake.
- Check the batch code printed on the box and the bottle: the two must match, and the code should look printed, not stuck on. Every unit we sell is batch-code checked on arrival in Seoul, and we verify any code for free — see how to check if Korean skincare is original.

Medicube TXA Niacinamide Serum: frequently asked questions
Is the Medicube TXA Niacinamide 15 Serum at Korean Skincare Pakistan original?
Yes. Korean Skincare Pakistan is an Official Authentic seller of Medicube in Pakistan. Our stock is bought from official Medicube channels in Seoul, every unit is batch-code checked on arrival and shipped from our Seoul warehouse. If a product is ever not original, an old batch or near expiry, you can return it free within 7 days.
Is the Medicube TXA Niacinamide serum good for pigmentation?
It is made for it. Tranexamic acid and niacinamide are two brightening ingredients often used together for dark spots, post-acne marks and uneven-looking tone. Results build slowly over several weeks of daily use, and only if you wear sunscreen every morning, because sun exposure keeps darkening spots. For melasma or patches that keep coming back, see a dermatologist.
Can I apply the Medicube TXA Niacinamide serum at night?
Yes. You can use it in the morning, at night, or both. At night, apply it after cleansing and toner, then seal with moisturiser. If you use it in the morning, always finish with a broad-spectrum SPF 50 sunscreen. Sensitive skin can start with evening use only and add the morning once the skin is comfortable.
Can I use Medicube TXA Niacinamide serum with vitamin C or retinol?
Yes, with care. A simple plan is vitamin C such as Medicube AGE-R Vita C Pro Ampoule in the morning and this serum at night, or this serum in the morning and retinol at night. If you layer two actives at once, introduce them one at a time and stop if your skin stings or peels. Sunscreen every morning is essential.
