About
What it is.
A dropper-bottle facial serum from Anua's Korean skincare line, built around niacinamide and tranexamic acid alongside alpha-arbutin, hyaluronic acid, and ceramides. The combination targets dark spots, post-acne marks, and uneven tone while the hyaluronic acid and ceramides work to keep the skin barrier supported during use. The texture is thin and fast-absorbing, meant to sit under moisturizer or makeup without residue.
It's formulated fragrance-free and positioned as vegan and cruelty-free, aimed at people managing mild hyperpigmentation or lingering redness from breakouts who already tolerate active ingredients in a routine. It is not built for very reactive or heavily acne-prone skin, and it isn't a fix for deep-set melasma or long-standing dark spots.
The verdict
The serum's 10% niacinamide and 4% tranexamic acid draw consistent praise for fast absorption and gentle hydration, especially for reactive skin, though the dropper bottle poses friction for travel and overspreading invites tackiness. At $22–$24, it aligns with buyer sentiment and AI assessment as a solid mid-range option.

Frequently asked
What buyers want to know.
What does this serum actually do?
Reviewers say the 10% niacinamide and 4% tranexamic acid combination visibly helps with mild dark spots and post-acne redness when used consistently. It also contains polyglutamic acid, alpha arbutin, and centella to hydrate and soothe.
How quickly will I see results on dark spots?
Reviewers warn this works on mild hyperpigmentation and post-acne marks, not deep melasma or old dark spots. One buyer noted they hadn't seen long-term sun spot fading after short-term use, so results take time.
Will this irritate my skin?
Reviewers agree the serum can irritate sensitive skin, especially with daily or twice-daily use, and recommend starting with once-daily or alternate-day application. Buyers rate it highly for suitability on sensitive skin, though one buyer reported significant irritation that forced them to cut usage drastically.
Who should and shouldn't use this?
Reviewers say it's best for people with mild uneven tone or post-acne redness who can tolerate actives and follow up with moisturizer. It's not for those with very sensitive, reactive, or active acne-prone skin, or anyone expecting fast results on deep or old marks.
Does it feel heavy or leave residue?
Buyers praise the fast absorption and lightweight texture, with a 4.8 rating for absorption. The serum absorbs nicely without residue, though over-application can cause stickiness.
Do I need to use it twice a day?
Reviewers disagree on frequency. Some recommend twice-daily use for best results, while others insist once daily or alternate days is safer to avoid irritation.
