Is Anua Niacinamide Serum Safe During Pregnancy? TXA Formulas Checked
Anua Niacinamide 10% + TXA 4% Serum currently scores 57, medium risk in MamaSkin. Niacinamide itself is not the problem. The serum also contains tranexamic acid, arbutin, alpha-arbutin and betaine salicylate. By contrast, the current Anua Niacinamide TXA Brightening Booster Toner scores 75, low risk.
Quick verdict: Do not read this as a simple niacinamide serum. It is a multi-active pigmentation formula. If you want the most conservative Anua option, choose a simpler product without the arbutin stack.

Why arbutin changes the answer
Arbutin is a glycosylated hydroquinone used to reduce pigmentation. MamaSkin places it in the medium-risk band because of hydroquinone-related uncertainty, possible release or contamination and limited pregnancy-specific topical outcome data. The signal is not the same as a proven retinoid risk, but it is enough to move the serum out of the easiest shortlist.
The AAD recommends avoiding hydroquinone during pregnancy. That does not make arbutin identical to hydroquinone, but it explains why a conservative pregnancy methodology does not treat the relationship as irrelevant.
Niacinamide and TXA are not the whole formula
Niacinamide is in MamaSkin's no-known-risks band and is widely used for barrier support and tone. Topical tranexamic acid is currently low risk in the ingredient library, with limited pregnancy-specific data. These two ingredients do not cancel the arbutin in the same bottle.
This is why hero-ingredient marketing can be misleading. A shopper sees "niacinamide serum" while the ingredient list describes a broader pigmentation treatment.
A simpler brightening routine
If you are managing melasma or post-acne marks:
- Use one brightening step, not several overlapping serums.
- Choose niacinamide, vitamin C or azelaic acid in a formula you tolerate.
- Use sunscreen every morning.
- Avoid retinoids and hydroquinone during pregnancy.
- Discuss stubborn pigmentation with a dermatologist rather than increasing irritation.
ACOG notes that melasma is common during pregnancy and recommends daily sun protection to prevent it from worsening. That foundation usually matters more than chasing a stronger percentage.
What the 10% and 4% claims do not tell you
Percentages make the serum sound precise, but they describe only the highlighted ingredients. They do not tell you that arbutin, alpha-arbutin and betaine salicylate also appear in the formula. They also do not predict how sensitive skin will respond to several brightening pathways at once.
A higher niacinamide percentage is not automatically more effective for every user. Concentrated niacinamide can feel sticky or irritating, particularly when paired with other active products. If a 5% product supports your skin without redness, moving to 10% is not a necessary pregnancy upgrade.
Read percentage claims as one piece of the product description. Then read the full INCI, the score and the reason for the band. For this serum, the medium-risk arbutin flag is more useful to the pregnancy decision than the large niacinamide number on the front.
