ANUA Niacinamide 10 + TXA 4 Serum, Hyaluronic Acid, Tranexamic acid, Facial Serum For GlassSkin, Glow Back Serum, Dark Spot Care, Postnatal Skincare, Korean Skincare (30ml/1.01 fl.oz)

I’m using it and so far I really like it. The serum is lightweight, absorbs quickly, and doesn’t leave my skin sticky. From the first few days, my skin felt more hydrated and looked more even. I’m still testing it to really see the results on dark spots, but it hasn’t caused any irritation or breakouts. I like how it leaves my skin soft with a natural glow. So far, it’s doing great and I’ll keep using it.

Best serum I’ve ever used. In less than a month, my acne marks started fading noticeably, and my skin looked clearer and brighter. I honestly didn’t believe the hype when I kept seeing it on TikTok and had pretty low expectations, but this proved me wrong. It boosted my confidence in my bare skin. Compared to the serum I used before that cost $48, this is a much better deal. It lasts over a month even when used twice a day (and even longer if used once daily). It’s very hydrating to the point where I sometimes don’t even need a moisturizer afterward. My bottle lasted about six weeks, and the results have been amazing: lighter dark spots, clearer skin, and a real glow.

This serum appears to be lightening my melasma slightly, though I can't say for certain if it's solely this product or a combination of changes I made - switching from chemical to mineral sunscreen and stopping my vitamin C oil around the same time. That said, I'm seeing improvement, so I'm happy to keep using it. The dropper delivers just the right amount of product without waste, and my skin doesn't feel oily or sticky after application, which is a huge plus. I use it once a day right after cleansing as the first step in my routine, then follow up with salicylic acid for spot treating, PDRN cream, and mineral sunscreen. The serum absorbs quickly and layers well with other products without pilling. The niacinamide and tranexamic acid combination seems effective for brightening and evening out skin tone. For the price point, it's excellent value for money - K-beauty serums with these active ingredients are typically much more affordable than Western brands with similar formulations, and you get a decent amount of product that should last a couple months with daily use. If you're dealing with hyperpigmentation or melasma, this is worth trying, just be consistent and patient with results.

This is a great product overall. To start off, I gradually integrated this serum into my skincare routine out of fear of upsetting the delicate balance of my combination skin - one drop every other day. In the first 2-4 weeks, I would see some small white heads here and there. When this happened, I'd minimize the amount of product used each day and/or the frequency in which I used it. 4 months in, I'm starting to experience some positive results. My skin tone has evened out overall. No more dark patches or spots. If I get a pimple, it clears, with minimal PIH. After a week or two, the spot is gone. Additionally, this serum helped me clear my combination dark circles (excess pigmentation and slight hollowness). Presently, I add three drops to my under eye area before using a topical retinol. I found this method to be a better course of treatment than OTC eye creams who advertise fixing this issue. Why? Because I was slowly able to customize the amount of niacinamide added to my under eyes over time, rather than shocking this skin with a new product all together. I don't like how this product is advertised by influencers - using two droppers full on the face in one sitting. I've found that if too much product is used on my skin, it becomes extremely sticky and uncomfortable. Half a dropper is enough when paired with consistency. Also, this serum has a higher concentration of niacinamide. So if you use other products with high concentrations, it could cause some irritation, inflammation, and hyper pigmentation. Hence, why I started low and slow. For full transparency, below is my skincare routine. I'm finally able to phase out make up, favoring tinted skin care products. But the key was going slowly with each product, adding one at a time and monitoring changes throughout my menstrual cycle. I'm 32. AM - Panoxyl (4%) - 10% Azelaic Acid - Vichy Mineral H.A. Serum (2 pumps) - 2-3 drops of this serum - Vanicream Vitamin C Cream - H.A. Moisturizer (specifically used under my eyes) - Thrive Causemetics SPF 50 Mineral Sunscreen (This sunscreen is also a moisturizer w/ Sodium Hyaluronate) - Typology Tinted Serums (I mix two shades match my skin tone) PM - Two Olay Melts or CeraVe S.A.

Moisturizer Other Products Used As Needed: - Vichy Normaderm S.O.S Acne Rescue Spot Corrector • At night on emerging blemishes (PM - as needed) • Thick layer on affected area • First apply a thick layer on, covering the blemish, then add other skincare products to non blemished skin. - The Ordinary Glycolic Acid 7% Exfoliating Toner • Appled with a clean cotton pad all over (AM/PM - twice a week) • For PIH, add to a paper towel and gently rub for 30 seconds (PM ONLY - as needed) * Follow up with Azelaic Acid to decrease any inflammation. - L'Oreal Paris Bright Reveal Dark Spot Exfoliant Peel, 25% AHA BHA PHA • Applied to my nose and chin only (PM - every other week - approximately 10 minutes) • Applied directly to a dark spot only (PM - no more than twice a week - 15 minutes) - depology Deepcare+ Serum-Infused Micro Dart Patche • Applied to under eyes or smile lines (PM - once a week)

This is one of the best products I’ve used for face acne and dark spots. The droplet formula is easy to apply, absorbs quickly, and helped clear breakouts while fading acne marks with consistent use. Just make sure to use sunscreen, because sun exposure can make dark spots worse while using this. Simple, effective, and worth it.

Excelente producto.

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.
