What they liked

  • Gentle enough for sensitive skin

What they flagged

  • Tacky finish, needs layering time
  • May not visibly reduce dark spots
  • Can feel heavy on very oily skin

What the gurus are saying

The 10% niacinamide makes this serum exceptionally soothing and effective for post-acne marks and hyperpigmentation, but it's a genuine risk for anyone who doesn't tolerate niacinamide well. Those who can handle it praise how gentle it feels despite the high concentration, and experts note the tranexamic acid and B12 add redness-reducing power. Results come slowly and work best as part of a full routine, not alone, and some find it hydrating enough to use all over the face rather than just spot-treating the darkened areas. For oily skin it may feel heavy; dry and mature skin tend to get more out of it.

Yay
"Really suitable for those that are struggling with dark marks in particular. If you're struggling with like post acne marks and have sensitive skin and worry about ingredients that lighten the skin that may contribute to irritation, I think this is definitely one to really incorporate into your routine. [...] You can use it all over for kind of that more gentle brightening your complexion because that 10% niacinamide would definitely do that. And you don't have to worry about causing white spots or blotches [...] around dark spots, or you can just apply to areas where you have dark spots to spot treat. Either way, I think it's acceptable. And with just how gentle this formulation is, you can definitely use it either way without having to worry about irritation or undesired lightening of your skin. This product is not going to do that."

"This is a niacinamide 10% dark spot correcting serum by Anua, and I really like this one. I normally don't tolerate niacinamide over 5%, but this one just does it for me. It's literally super soothing, the ingredients formulated in here are so great for the skin, it's super gentle on the skin, and it is super functional."
Yay
"I've seen the Anua Niacinamide 10% + TXA 4% Dark Spot Correcting Serum go viral multiple times and I think that it could be helpful in this case. Niacinamide can help with oil production as well as brightening the skin from post-inflammatory hyperpigmentation from the acne marks. The tranexamic acid helps with hyperpigmentation. So this would be something good for people who deal with hyperpigmentation from acne."
Yay
"This is the Anua Niacinamide 10% Tranexamic Acid. I really liked this. Now, 10% niacinamide is on the higher end, above and beyond what is necessary. 5% max is really what has been shown to do anything, which includes improving hyperpigmentation, redness, the moisture barrier, anti-aging purposes, skin yellowing. 10% maybe more likely to cause irritation. And then some of you out there are already like no more niacinamide, so for those of you who cannot do niacinamide, this is off the table. This also has tranexamic acid. Applied topically, it seems to help with redness. Not a ton of data out there with regards to topical tranexamic acid, but that's really where it seems to shine, and possibly because some evidence suggests that it's helpful for improving barrier function. Ultimately, that could help reduce irritation that leads to redness. Plus, this has this kind of pinkish, reddish tint to it, which comes from B12, topical B12. Not a ton of data, okay? But the data that we do have suggests it might be helpful for reducing itch. I love B12 and things, and I'm hoping to see more of it. Anua, this was really good. I ended up really liking that."

Anua Niacinamide 10% + TXA 4% Serum Review
"I really enjoyed it. I think it is a good serum provided you are not someone who is irritated by niacinamide especially at higher percentages. I think it is a well formulated serum. It's hard to predict with something like this to what extent you're going to see results because it is a cosmetic that hasn't been put through a rigorous clinical trial as its own product. The ingredients have research to support their efficacy but the product formulation overall, we don't really have clinical trials to predict how efficacious it might be for you. The extent of results that you might see from something like this are going to be very dependent on the nature of the redness and the hyperpigmentation that you might be dealing with. Hyperpigmentation and redness tend to be a lot more stubborn, a lot trickier to fade, take a lot longer to fade. If the underlying inflammatory process say acne went on untreated, uncontrolled for a long time, the more inflammation in the skin, the more stubborn the post acne dark marks and redness are going to be to fade. But if say you just had a little zit here or there and it healed with a little dark mark that you typically get, you might find that this particular serum helps it fade a bit more quickly provided of course you are not irritated by it."

"They named this a dark spot correcting serum, but I didn't really see a difference in my dark spots, and honestly this isn't even that popular here in Korea compared to other Anua products. I don't get why it's viral, but I do like it, it finishes a little tacky and you can just use it as a hydrating serum. I'd put this at a B."

"I was looking for a Korean serum with niacinamide and this is it. In terms of hydration it's a little lighter and easier to like for more people, so if you have oily combo skin and want a light everyday serum this one is better. I'll go with Anua."

Global No.1 vs Korea No.1 Skincare: Which is Better and Why?
"Anua's serum has ten percent niacinamide and four percent tranexamic acid, so on paper the ingredients should give a brightening effect, but mixing them all together doesn't guarantee the effectiveness, and the majority of Korean reviews say it's not working. Still, it wasn't a bad product because of how moisturizing it is, it has ceramide and panthenol in it, so I'd recommend it more for dry, mature skin. For oily skin it can feel a little too heavy."
Yay
"One little serum is not really going to cut it when it comes to pigmentation for skin of color but it's a good start. So for me this is Dr V approved."

"My number one recommendation, which has been my recommendation since the month of May, is the niacinamide and transacid serum. 10% niacinamide plus transacid. This will take time to work but this works beautifully. With transacid individually, whether you're using it from other brands, pure transacid, dryness and irritation with this product I've heard of no such things. I think it is such a beautiful product. So even if you're struggling with melasma or pigmentation or any of these acne mark related situations, 100% use this. And then you can use your retinol, you can use whatever else. This is a serum that is worth integrating. It is absolutely fabulous."

"I don't do well with these high levels of niacinamide. I was actually seeing my skin looking more irritated, I was getting more breakouts, so I just kind of gave up on this one. This just is not for me."

I Can't Finish These...My Mistakes & Product FAILS
"This is the Anua Niacinamide 10% and Tranexamic Acid 4% Serum. I had to stop using this because it's just not working for me, my skin got more congested and a little more irritated and sensitive while using it. I'm not surprised, because niacinamide at higher levels typically doesn't work for my skin, even though I love niacinamide at low levels and use it all the time."
Yay
"This is their Anua 10% niacinamide, 4% tranexamic acid. And interestingly, as far as other actives in this, they have 2% arbutin, which they don't highlight on the front, but it's also a really important ingredient in this cocktail to really target and brighten that skin. The ingredient profile is unique and complementary because when you think about dark spots, not only do you create pigment through tyrosinase, but then you also transfer the pigment through melanosomes and then it also is taken up in the keratinocytes or skin cells. So the ingredient profile here, especially with niacinamide and the tranexamic acid, it does add multiple mechanisms by which this works. Now, a lot of ingredients that treat dark spots can be irritating. So nicely, this product also coupled a lot of soothing ingredients to help offset that. So you have things like PGA, hyaluronic acid, and ceramides to soothe and it couples nicely with just this almost like hug to your skin that the serum gives you. So not only does it treat it, but it also kind of helps protect it from it. This is a beautiful pink serum. I love a colored serum, and I am a sucker for the way their products look."

"In terms of dark spot products that could be better, this is a pretty good deal from Anua. This is their transexemic acid and niacinamide 10% serum. So you got both combination of transexemic acid and niacinamide. Plus it's 30% off which is a pretty good deal."

What you want to probably use is an entire pipet of it for the face and then dab it in the skin. Get it into the beard. Apply it the neck. When you're treating any type of discoloration, you don't want to just spot treat. You do want to use it over the entire face."
Skincare That You DON'T NEED (But Might Want)
"This one in the morning which has hyaluronic acid in it, and those two together you could get some synergy. It's not like one or the other, you could go with just one, you could go with just this one, or you could use this at night and this in the morning. That's going to be up to you, but I think overall for me, this is skincare you might want and might need. You might actually need this and you also might actually want this. It definitely is a good product."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Vitamin C

Topical vitamin C is an antioxidant with reasonable evidence for dullness and uneven tone. It breaks down in light and air, so how a product is formulated and packaged matters as much as the percentage on the front.

Source: DermNet

Niacinamide

Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

Source: DermNet

Salicylic acid

Salicylic acid dissolves in oil, so it can get into a pore rather than just working on the surface. That is why it has long-standing evidence for blackheads and milder acne.
