If you’re like me, always on the lookout for a brightening serum that works without irritating your skin, you’ve probably come across Anua’s Niacinamide 10% + TXA 4% Serum. I’ve tested it for a full month, and here’s my honest, no-filter review.

Why I Chose It

  • 10% Niacinamide – a powerful ingredient to control oil and brighten skin tone
  • 4% Tranexamic Acid (TXA) – helps fade dark spots and post-acne marks

The formula looked promising, especially since I have sensitive, combination skin and was looking for something gentle yet effective.

First Impressions

  • Texture: Lightweight and fast-absorbing
  • Scent: Barely noticeable (a plus!)
  • Application: No stickiness or irritation

My Results After 4 Weeks

Used every morning before moisturizer and sunscreen.

  • Skin looked brighter and healthier
  • Dark spots and old acne marks lightened slightly
  • No breakouts or purging – which was a huge win for me

Pro Tips

  • Works great for oily to combination skin types
  • Don’t mix with Vitamin C in the same routine – it may cause irritation
  • Be patient – results build over time

Would I Repurchase?

Absolutely. It’s a rare combo of effective yet gentle ingredients – and it delivers on its promises without drama.
