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

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

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.

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!

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

I absolutely love this serum! The combination of Niacinamide and Tranexamic Acid has worked wonders for evening out my skin tone and fading stubborn dark spots much faster than other products I’ve tried. It’s incredibly lightweight, absorbs quickly without any sticky residue, and keeps my skin feeling hydrated. A total game-changer for my skincare

Earlier in the year, I gave into the hype that was the viral pink PDRN serum and had the WORST reaction to it. My skin is extremely sensitive and I’ve been using k-skincare exclusively for over 10 years. So color me surprised when the serum made me break out with deep, bright red cysts all over my nose and forehead. Enter Anua. Struggling to get rid of the acne and the stubborn dark red acne scars, I decided to try out this serum. If we’re honest, I was terrified that I was going to react badly to this, too. But I can confidently say that this serum saved my skin. My advice is to give it time and use it both morning and night. The first photo is my skin in March, the second is my face in May. I’m on the fence about repurchasing (purely because I want to target the hyperpigmentation caused by the aforementioned serum), but if I find myself with another intense reaction, I will absolutely buy another bottle.

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.
