Post-acne dark spots have always been more persistent for me than acne itself. My skin is combination and acne-prone, and while active breakouts usually calm down with the right care, the marks they leave behind tend to stay much longer. Because of this, I approach brightening serums with caution. I look for formulas that work gradually, support the skin barrier, and don’t introduce irritation while addressing pigmentation.
This review is based entirely on my personal use of the Anua Niacinamide 10% TXA 4% Serum, observed over consistent use as part of my regular routine.
About the Brand: Anua
Anua is a Korean skincare brand that focuses on minimal, barrier-respecting formulations. Rather than relying on heavy fragrance or overly aggressive actives, the brand positions its products around ingredient clarity and skin compatibility. This approach becomes especially relevant for acne-prone skin, where inflammation and over-exfoliation often worsen pigmentation instead of improving it.
The TXA Niacinamide Serum reflects this philosophy by combining higher-percentage actives within a formulation that still feels controlled and wearable.
Ingredients and Formulation:
At the center of this serum is 10% Niacinamide, an ingredient widely studied for its ability to regulate oil production, support the skin barrier, improve texture, and gradually reduce post-inflammatory hyperpigmentation. While 10% can feel intense in poorly balanced formulas, my skin tolerated it well, suggesting that the formulation includes adequate buffering and hydration.
The serum also contains 4% Tranexamic Acid (TXA), which works differently from exfoliating acids. Instead of increasing cell turnover, TXA helps interrupt the pathways involved in excess pigment production. This makes it particularly effective for acne-related dark spots without causing peeling or sensitivity, especially when used consistently.
To complement these two actives, the formula includes 2% Alpha Arbutin, which supports tone correction by helping reduce the appearance of discoloration over time. Rather than offering instant brightness, this ingredient contributes to a more even complexion with regular use. Together, these percentages suggest a formulation designed for steady correction rather than quick but disruptive results.
Texture, Colour, and Sensory Experience
The texture of the Anua TXA Niacinamide Serum is lightweight and fluid, allowing it to spread easily across the skin. It absorbs quickly without leaving a sticky or greasy residue. The serum has a shade of pink colour to it making it aesthetically pleasing too, and importantly for me, it has no strong or noticeable fragrance. This made it comfortable to use consistently, especially alongside other active products.
Packaging
The serum comes in minimal, functional packaging with a dropper that allows controlled application. It feels practical for daily use and aligns with the brand’s understated aesthetic. The design prioritizes usability over decoration, which I personally appreciate.
How I Incorporated It into My Routine
I primarily use this serum in my evening routine, after cleansing and toning. On certain nights, I apply it after VT Cosmetics Reedle Shot 100, a step that can increase skin sensitivity for some users. Despite this layering, I personally experienced no redness, irritation, or discomfort. My skin remained calm, which points toward a well-balanced formulation rather than an aggressive one.
Observed Results Over Time
With consistent use, I noticed a gradual fading of post-acne dark spots. The improvement wasn’t instant, but over time, the marks appeared lighter and less prominent. My overall skin tone looked more even, and I did not experience breakouts, congestion, or increased sensitivity during use.
What stood out most was how seamlessly the serum fit into my routine without demanding adjustments or recovery days.
Based on my experience, this serum supports pigmentation correction and tone balancing over time. It does not claim to exfoliate, resurface, or deliver instant brightness, and I think that distinction matters. Its strength lies in consistency and formulation balance rather than dramatic overnight changes.
Final Thoughts
For my combination, acne-prone skin, the Anua TXA Niacinamide Serum delivered steady, comfortable results without irritation. It feels suitable for those looking to address acne marks with a fragrance-free, lightweight formula that prioritizes skin compatibility alongside active performance.
