Anua Niacinamide 10 + TXA 4 Serum, Dark Spot Care, Hyaluronic Acid, Tranexamic Acid, Lightweight & Hydrating All-in-One Daily Facial Serum for Glass Skin, Korean Skincare, 1.01 fl.oz

This serum has quickly become one of my favorite skincare products. It feels lightweight, absorbs beautifully, and leaves my skin looking healthy and radiant. I’ve noticed my complexion appears more even and my dark spots are gradually improving. It works well under moisturizer and makeup without feeling greasy. The quality, packaging, and overall experience exceeded my expectations. I would definitely purchase again and recommend it to others.

I’ve been using this serum for a few weeks and I’m really impressed. It’s lightweight, absorbs quickly, and doesn’t feel greasy. My dark spots have started to fade, my skin looks brighter, and my complexion feels more even. It layers well with my moisturizer and sunscreen. Definitely a great addition to my skincare routine and worth trying if you’re looking for a gentle brightening se

Really is the best stuff for dry, mature skin. Doesn't leave your face greasy or oily. Literally makes me look younger by the next day!

I don’t typically write reviews unless I find it necessary. I have genuinely never found any serum or moisturizer that has worked this good. I have struggled with cystic acne and dry skin / premature aging for quite a while now, im only 20 years old but my skin was pretty fried i guess idk how to explain it. i’ve only used this serum twice now, overnight and this morning. tell me why my acne scars are ALREADY ALMOST GONE?? 😭 IT HASNT EVEN BEEN A FULL DAY. i know it sounds too good to be true but literally let me show you my skin rn, sorry i don’t have a before pic but it’s pretty self explanatory. i would say this serum brightens, hydrates, smooths, ans glassifies. i wouldn’t recommend on oily skin, this would best suit aged skin or dry skin users. it like brought my skin back to life in 1 use

I really enjoyed this product, and one bottle lasted me about a month and a half. After the first application, I noticed an immediate boost in hydration. Once the product fully absorbed, it left a slightly sticky feeling, but that wasn’t a problem since I followed up with my moisturizer. The next morning, my skin felt a bit greasy in my T-zone, although my T-zone is naturally oily, so that wasn’t unusual for me. After about six weeks of use, I didn’t notice any significant improvement in my dark spots or freckles. Around week three, I started noticing blackheads on my cheeks, which is something I had never experienced before. I also began getting an occasional pimple. During the last two weeks, I stopped using my moisturizer and applied only the Anua product, and that’s when I started breaking out more frequently. After finishing the bottle, I decided to try another product from the same brand to compare results and see which one works better for my skin. Overall, I would recommend this product for its excellent hydration and its ability to create a “glass skin” effect. It definitely delivers in those areas. If you have very sensitive or acne-prone skin, you may want to start by using it every other day instead of daily to see how your skin responds.

I have had melasma on my forehead for about 2yrs now. On my bare skin it’s sorta noticeable but only if you sit there and stare at my forehead. It gets really noticeable when I wear makeup, it looks GREY. I’ve had prescription creams brought from Mexico and nothing seemed to help. I finally did a little research and found a couple of products on here but the price was too much for my liking. I finally decided to buy this product and at first I started using a heavy layer of it which in turn started to cause me cystic acne. I stopped for a few days, did a facial scrub and started it again with a THIN layer. Since then my melasma is improving, and my old acne scars are starting to fade! I’m not sure if the improvement is in conjunction with the facial scrub or a chemical peel from the brand the ordinary that I’ve started to use when I started this serum. Regardless, it’s working for me and I feel much better each day I look in the mirror and I see improvement. It’s worth the money. Give it a try. UPDATE 3/31/26 My melasma has improved tremendously, but now there’s a clear pixelated look to it😂 I have stopped using the facial scrub and moved on to a glycolic acid from the ordinary. The chemical peel and glycolic acid are giving me the benefits of smooth textured skin, I do notice just a tiny bit of peeling but, it’s nothing alarming. I moisturize with elf brand holy hydration unscented with SPF 30, then follow it up with the ordinary SPF 45 if I’m going to be outside. Products I use: elf holy hydration facial cleanser, the ordinary niacinamide serum, anua 10+, elf holy hydration moisturizer spf 30 unscented. The acids like the ordinary chemical peel, I use once every 2 weeks, and the ordinary glycolic acid twice a week. Through trial and error and a little research I’ve figured out that when I do my chemical peel, I should avoid the anua serum for at least 5 days, just stick to cleansing and moisturizing. On the nights I do my glycolic acid, I wait 1 hour, then apply the niacinamide, wait for it to absorb, then apply my moisturizer. Next morning I cleanse, niacinamide, anua, moisturize, then spf 45 if I’m going out. It seems like a lot and the reason I took so long to finally take care of my face was because I felt like I didn’t have the time for it. Once you start giving your products time to function, you start to enjoy doing your facial routine. That’s where I’m at in my journey. I hope my long rant helped.

I’ve been using the Anua Niacinamide 10 for just a week, and I am already absolutely in love with it! My pores look noticeably smaller, and it leaves my skin looking incredibly glowy. As someone whose skin went through severe acne, I’m thrilled to see how much it’s helping with my leftover scars, dark spots, and redness. It’s super gentle but highly effective. Highly recommend!

I purchased this ANUA niacinamide serum specifically because I’d heard it was good for acne-prone skin. I have combination, acne-prone skin and was hoping it would help reduce breakouts and fade some existing dark spots. Unfortunately, I used the entire product without seeing any noticeable improvement. In fact, during the time I was using it, I experienced a breakout — though I can’t say with certainty it was caused by the serum. My dark spots also showed no visible improvement. I ended up stopping use altogether. It’s possible it needs a longer period to show results, but in my experience it simply didn’t work for my skin type. To be fair, from the entire ANUA line, the hydrating cream was the only product that genuinely impressed me — that one delivered real results. But this serum and the rest of the line didn’t quite convince me. May work differently for other skin types, but for acne-prone combination skin it wasn’t the right fit for me.

C’est un sérum qui s’intègre facilement dans une routine sans laisser de fini collant. La texture est légère et pénètre vite, donc on peut enchaîner sur sa crème sans attendre. Au bout de quelques semaines, on sent vraiment l'action du duo niacinamide et acide tranexamique : les taches pigmentaires et les petites marques post-imperfections s'estompent visiblement, et le teint devient plus homogène. Ça aide aussi pas mal à calmer les poussées de boutons et à lisser le grain de peau. Il faut juste rester attentif si on a la peau très sensible, car 10 % de niacinamide ça reste une concentration sérieuse, mais pour cibler les taches et les imperfections en même temps, c'est une option très cohérente.

Llevo un rato comprándolo y esta vez llego con dos sobrecitos de prueba, y para ser honesta es un excelente producto, yo tengo piel grasa y su sensación es super ligera ademas de que si, definitivamente ayuda con la apariencia de la piel.

Lo estoy utilizando junto con el serum APAD de Geek and Georgeous y, con paciencia (esto es cuestión de tiempo), estoy notando como se me están empezando a difuminar unas manchas de granitos que tenía. No sé si insistiendo con más botes, podré conseguir lo que me gustaría. Esto lo uso por las mañanas. Las dos cosas. Y por la noche, retinol. Es una buena textura, ligerita, no tiene perfume fuerte y deja la cara un poco pegajosita, perfecta para la crema hidratante o de sol después.

Ottimo siero! Lo sto usando da un po’ e posso dire che ANUA si conferma un brand validissimo. Questo siero in particolare mi ha aiutata tantissimo con le imperfezioni: brufoletti, rossori e piccole macchie post-acne risultano molto meno visibili già dopo le prime applicazioni. La texture è leggera, si assorbe subito e non appiccica, quindi è perfetto sia per pelli miste che più sensibili. Lascia la pelle luminosa, uniforme e più compatta nel tempo. Nel complesso è davvero un ottimo prodotto da inserire nella skincare routine se cercate qualcosa che aiuti a controllare le imperfezioni e migliorare l’aspetto generale della pelle. Consigliato!

I’ve been using the ANUA Niacinamide 10 + TXA 4 Serum with Hyaluronic Acid for two months, and I’ve slowly been seeing a dramatic improvement in my skin’s texture, tone, and overall brightness. According to the ONSKIN app, it rates 99 out of 100, meaning it has a very clean ingredient list and low risk for your skin barrier. I’ve attached photos below for reference. Helpful tips and things to know: • Apply 2–3 drops on clean skin before moisturizer, morning and night. • Layer under sunscreen during the day to protect and boost brightening effects. • Patch test first if you have sensitive skin, though the clean formula is low-risk. • Can be layered with other hydrating serums (like hyaluronic acid) or calming products without irritation. • Avoid applying heavy oils immediately afterward to prevent pilling. • If using under makeup, give it a few minutes to fully absorb to avoid residue. • Works on dark spots, uneven tone, redness, and minor texture issues over consistent use. • Consistency is key — results may appear gradually over several weeks, as I experienced. • Store in a cool, dark place to maintain stability and efficacy. Overall, it’s a safe, effective, and easy-to-use serum that delivers real results over time, and the ingredient quality gives extra peace of mind.
