The highest niacinamide serum named here is The Inkey List's 20% SuperSolutions, but the biggest number is not always the best pick. I go through twelve serums, from niacinamide-led formulas to blends where it plays support.
Highest Niacinamide Serum: 12 Picks Beyond the Biggest Number

Niacinamide is a form of vitamin B3, and the Cleveland Clinic describes it as a multipurpose skincare ingredient that can support the skin barrier, calm redness and brighten tone. That list is why nearly every brand has a bottle of it, and why shopping for the best niacinamide serum can feel like reading a spec sheet. I start with the fine print. The same clinic is plain that nothing has been proven to shrink the actual size of pores, only to help them look smoother and less noticeable, which is a useful thing to keep in mind before you buy a niacinamide serum for pores. The founder story I keep coming back to is Paula Begoun's. She was an investigative reporter who, at 25, read the label on a product she was using and found acetone, nail polish remover, as the fourth ingredient. She went off to read every piece of research she could find, wrote books, and in 1995 launched Paula's Choice on the strength of that reading. Her 10% Niacinamide Booster opens this edit, and it is exactly what a researcher's label looks like: one ingredient stated loudly, with vitamin C and licorice extract alongside. The Inkey List goes higher at 20% with zinc PCA and squalane, Medik8 pairs 10% with a peptide, and Facile keeps it at 5% next to azelaic and tranexamic acids.

Partners, Tints and a Cherry Toner
The second four put niacinamide beside a partner, and this is where each brand's personality shows. Beauty of Joseon builds its whole line on the Gyuhap Chongseo, a Joseon era encyclopedia written by a female scholar named Yi Bingheogak, and the brand says propolis and green tea come from it. The Glow Serum is cushiony, with propolis and a little BHA, and feels more like a hydrating gel than an active. Glow Recipe began in 2014 as an online shop for Korean brands and only launched its own formulas in 2017, which explains why Hue Drops feels so edited: two sheer tints, watermelon and centella in a light gel. Biodance pairs pineapple water and glutathione, a sensible pick if you want niacinamide for dark spots and texture in one step. Fenty Skin arrived in 2020, three years after the makeup launched in September 2017, and Fat Water is the playful one, a toner serum that smells of cherry and sunkissed fig. Press it in with your palms after cleansing.
Blends, Founders and Patience
The last four are blends where niacinamide is one player among several, and each has a founder with a story. Dr. Shereene Idriss is a New York cosmetic dermatologist who began posting skincare videos from her bed on Instagram in 2018 and launched her own line in 2022. Major Fade pairs alpha arbutin and kojic acid with niacinamide. Katherine Power founded Merit and launched it in January 2021, and Great Skin is a lightweight bi-phase serum with a hyaluronic acid complex and cacao seed extract. Charlotte Tilbury launched her brand in 2013 after two decades as a makeup artist, and Charlotte's Magic Serum uses golden vitamin C, polyglutamic acid and 5% niacinamide. Innisfree mixes green tea water and encapsulated hyaluronic acid with panthenol. What I would skip is starting with the highest percentage because the number looks impressive. The Cleveland Clinic advises beginning slowly with a low concentration if your skin is sensitive, and says niacinamide can be used once or twice a day after gentle cleansing.
A Shelf You Can Actually Keep Up
I would pick one serum from this edit and live with it, instead of stacking three. Match the partner to what bothers you: zinc and squalane for shine, propolis for comfort, arbutin and kojic acid for marks, hyaluronic acid for a plumper feel. Read the label beside the niacinamide, because that is where the real decision sits. If you have eczema, rosacea or any skin condition, the Cleveland Clinic says to check with a dermatologist before adding something new. If you want to keep browsing, I also put together BioSilk Silk Therapy and Bakuchiol Serum, the Retinol Substitute That Actually Holds Up.
