The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, Anua's Niacinamide 10% + TXA 4% Serum has emerged as the go-to formula when fading post-acne marks and stubborn dark spots is the priority. Threads on r/KoreanBeauty and r/koreanskincare consistently describe visible fading of hyperpigmentation starting around weeks 3–4 and more substantial change by month 2, with a lightweight, non-sticky finish that layers cleanly under sunscreen. The pairing of 10% niacinamide with 4% tranexamic acid is what reviewers most often credit for results that pure-niacinamide formulas don't deliver as quickly.
What reviewers liked
- Combines 10% niacinamide with 4% tranexamic acid for hyperpigmentation, a more targeted formulation than most competitors
- Multiple subreddit threads report visible fading of post-acne marks within 3–8 weeks
- Lightweight, fragrance-free texture that layers well, per r/koreanskincare and Ulta verified-purchase reviewers
- Large Amazon base (14,000+ reviews) with consistent 4.5-star average
Where it falls short
- r/Melasmaskincare thread flags inconsistent results for true melasma
- Brand visibility is limited in some high-trust specialist communities, reducing independent scrutiny
- Pricier than The Ordinary's 10% serum without dramatically different niacinamide content
- A subset of community reviewers note slow results requiring 2–3 months of daily use

Disagreement to flag honestly: a thread on r/Melasmaskincare reports the serum working initially and then dark spots darkening again, and one r/KoreanBeauty post notes that Anua as a brand has been banned on r/AsianBeauty, which limits the volume of unfiltered specialist-community discussion. Most retailer-customer reviews on Ulta skew strongly positive, but those are medium-trust signals; the more cautious read is that this is a well-formulated dark-spot serum that works well for many users but isn't a guaranteed melasma solution.
