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

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

This serum is really popular for a reason. It helps brighten the skin and improve the look of dark spots and acne marks over time. The texture is a bit thicker than typical serums, but it absorbs well once you apply a small amount. After consistent use, skin can look more even, smooth, and glowy. It’s strong though, so some people with sensitive skin may need to start slowly.

This has been my favorite serum. I can really notice a big difference in my pores, but it's something you have to use consistently. I also saw that they have a toner and niacinamide pads, so since I started using all of them together, the difference in the appearance of my pores has been huge... something you can notice within just a few days. So serum is amazing, but if you use the niac pads + niac toner + this serum you will notice a HUGEEEE difference if you have issues with your pores. It doesn’t leave my face greasy. I have sensitive skin, and I've been using it for about 8 months now and it has never caused me any issues.

I had been searching for something that actually worked on my sun spots, and this Anua serum exceeded all my expectations. From the very first bottle, I could already see my spots starting to fade. By the third bottle, they were noticeably softer and much less visible. The texture is lightweight, absorbs quickly, and leaves no sticky residue. I use it morning and night, and pairing it with sunscreen during the day makes the results even better. If you have sun spots and have tried everything without results, this is the product you’ve been missing. I’m already on my third bottle and won’t be stopping anytime soon. Highly recommended!

It takes time to effectively. Good for melasma , not really for acne scars

This complements my skin so well and makes it shiny and moisturized. Need more that 1 bottle for the entire skin to clear up but you start seeing a difference in your skin 1 week in . Not bad for price and it works well.

I love the texture and feel of my skin after using this product. No irritation. Skin visibly brighter after each use. Fragrance free.

When I first bought it, it helped my skin get right of acne scars so much! This and the numbuzin 5. But when I took a break and repurchased, seemed to have broke me out sadly and I did slowly build it up in my routine and once I stopped it, I stopped breaking out so this was in fact the culprit but I gave it 4 stars for doing its job in the past!

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.
