Children aged 3 and under: the Korean notice rules it out
Watch out: Its ranked listing is a two-bottle set, not the single bottle. The Amazon US list has the same ingredients in another order, so the formula is not confirmed.
Texture: Dropper bottle.
Label caution: The Korean notice says not to use it on children aged 3 and under, and notes that arbutin has caused papules and mild itching in human-application test data.

The Ordinary
Niacinamide 10% + Zinc 1%
60 ml
The Ordinary's Niacinamide 10% + Zinc 1% is the one non-Korean serum here: it is made in Canada and climbed from #71 to #14 in Olive Young Korea's skincare ranking between 6 Sep and 13 Oct 2026. Its Korean notice has 11 ingredients, with niacinamide second at 10 percent and zinc PCA fourth. The 60 ml listing holds 4.7 from 14,860 Olive Young reviews, and Hwahae shows 4.11 from 3,686 (14 Oct 2026).
Good for
You want few ingredients and a large review base
Skip it if
You only buy Korean brands
Watch out: Hwahae rates it 4.11, the second lowest of the five. Amazon US sells the 30 ml bottle and shows no ingredient list to compare.
Texture: Dropper bottle.
Label caution: The Korean usage text recommends a patch test before use and says to stop if irritation occurs.

DERMA FACTORY
Niacinamide 20% Serum
30 ml
DERMA FACTORY's Niacinamide 20% Serum ranked on all three dates and was #3 among essences and serums by sales at Olive Young Korea on 14 Oct 2026. Its Korean notice names just three ingredients: Damask rose water at 64.5 percent, niacinamide at 20 percent and glycerin at 8 percent. The single 30 ml listing holds 4.8 from 23,042 Olive Young reviews, the most of these five.
Good for
You want the most niacinamide per bottle of these five
You want a plain bottle, not a promo set
Skip it if
Skin that reacts to high niacinamide percentages
Watch out: The Korean notice names only three ingredients, so we could not check the full list. Its median rank, 45, is the weakest of the three serums that ranked on all three dates.
Texture: Pump bottle.

PDRN Niacinamide 10% Glow Serum
30 g
primera's PDRN Niacinamide 10% Glow Serum is in on Olive Young Korea's essence and serum sales list: #18 on 14 Oct 2026, though it missed all three skincare Top 100s. Its Korean notice lists niacinamide third, then panthenol, hydrolyzed DNA, glutathione and titanium dioxide with iron oxide for color. The Amazon US listing we link, sold by primera, shows the same 41 ingredients in the same order.

Watch out: Hwahae shows 4.00 from just 29 reviews on 14 Oct 2026. Amazon US sells a 25 g bottle; Korea sells 30 g.

DERMA FACTORY
Niacin Tranexamic 13% Serum
30 ml
DERMA FACTORY's Niacin Tranexamic 13% Serum takes the last place on our rule: #76 on Olive Young Korea's essence and serum sales list on 14 Oct 2026. Its Korean notice names four ingredients: sea buckthorn water at 65 percent, niacinamide at 10 percent, tranexamic acid at 3 percent and ethyl ascorbyl ether at 1 percent. Hwahae gives it 4.37 from 122 reviews (14 Oct 2026).
Good for

Skip it if
You want a serum with a long sales record in Korea
Watch out: Its Olive Young listing had only 12 reviews on 14 Oct 2026. The Amazon US listing shows no ingredient list, so it was not compared.
Texture: Amber pump bottle.

How we picked
Pool: every serum, ampoule or essence whose Korean product name says niacinamide (Olive Young category: essence/serum/ampoule; promo brackets ignored) in Olive Young Korea's skincare sales ranking Top 100 on 6 Sep, 1 Oct and 13 Oct 2026, plus the 144 best-selling items in that category on 14 Oct 2026. Every pick's Korean ingredient notice lists niacinamide in its top three.
Left out: listings that bundle several different serums, and names that say niacinamide only inside a promo bracket. Creams and pads with niacinamide are other categories.
Order: how many of the three Olive Young Korea skincare rankings each serum appears in, then its median rank (missing = 101), then its place in the essence/serum/ampoule sales list on 14 Oct. Price and commission play no part.
1 of the 5 products with an Olive Young Korea rank reached it through a promotional listing (influencer pick, Olive Young pick, collab or sale).
Ranked products that came from a gift-set or bonus listing (an extra item or a second unit in the pack): 2 of 5 — a rank can partly reflect the deal.
None of these was tested on skin by us; the order comes from the Korean data on this page.
For most US readers, Anua's Niacinamide 10 TXA 4 Serum is the pick.
It was in Olive Young Korea's skincare Top 100 on 6 Sep, 1 Oct and 13 Oct 2026, with the highest median rank of these five, and its Korean list puts niacinamide third at 10 percent. The Amazon US listing we link ships from Amazon.
Which niacinamide serum do Koreans buy the most right now?
Anua's Niacinamide 10 TXA 4 Serum, by our three-date rule. It placed #61, #13 and #13 in Olive Young Korea's skincare ranking on 6 Sep, 1 Oct and 13 Oct 2026. On the essence and serum sales list of 14 Oct, DERMA FACTORY's 20% serum and The Ordinary's serum sat higher, at #3 and #5.
Is the Anua Niacinamide 10 TXA 4 Serum worth it?
Anua's serum is worth a look if Korean sales matter to you: it ranked on all three dates, #13 on 13 Oct 2026. The catch is a middling Hwahae score, 4.27 from 484 reviews on 14 Oct 2026, and a US listing whose ingredient order differs from the Korean notice.
Why is The Ordinary on a list of serums Koreans buy?
Because Koreans buy it. The Ordinary is a Canadian brand, but its Niacinamide 10% + Zinc 1% was in Olive Young Korea's skincare Top 100 on all three of our dates, #14 on 13 Oct 2026. We allow at most two non-Korean brands in a list of five, and only with Korean sales data. Our list of foreign brands Koreans buy covers more of them.
Which niacinamide serum is right for my skin?
Start from the ingredient lists, since we did not test these on skin. The Ordinary has 11 ingredients and DERMA FACTORY's notice names three, while Anua lists 51, including arbutin and betaine salicylate. primera's list has colorants, so skip it if you want a clear serum.
Is 20% niacinamide better than 10%?
A higher number only tells you how much of the bottle is niacinamide; we did not test what it does on skin. DERMA FACTORY's notice states 20 percent, while Anua, The Ordinary and DERMA FACTORY's Niacin Tranexamic serum state 10 percent. If your skin reacts easily, starting with a lower percentage is the cautious choice.
More questionsCan I use these serums together with vitamin C?
Several already combine them on one list: Anua and primera list 3-O-ethyl ascorbic acid, and DERMA FACTORY's Niacin Tranexamic serum lists ethyl ascorbyl ether. If you add a separate vitamin C serum, follow each brand's directions and add one new product at a time.
Is the niacinamide serum on Amazon US the same as in Korea?
primera's is, as far as the list goes. Its Amazon US listing showed the same 41 ingredients in the same order as Olive Young Korea's notice on 14 Oct 2026. Anua's Amazon US list has the same ingredients in another order, and The Ordinary's and DERMA FACTORY's Amazon US pages show no full list we could compare.
Why is Anua's serum also on another of our lists?
Because its Korean name names a concern as well as niacinamide. Anua's serum also sits on our list built from concern words in Korean listing names; this page sorts by the ingredient in the name instead. The other four picks here are not on that list.
