Premium Azelaic Acid 10% Serum 1 Fl Oz – Niacinamide & Panthenol Face Serum for Blemish-Prone, Redness-Prone & Oily Skin – Lightweight Aloe-Based Korean Skincare (30 ml)

Really enjoy this product! I've repurchased it something like 6x times now. Maybe more. It gets me through at least a month and a half each bottle, and maybe up to 3 months? It's affordable, it feels amazing, it helps soothe your skin, and helps repair and clear up your skin. It absorbs really well. It's one of the few products I use almost every day (unless I'm in a rush, and even then, I tend to use this over the rest of my routine.) I'm not sure if it's "brightened" my skin, but it's definitely helped with the moisture and keeping my skin clear. I have *extremely* sensitive, dry skin, and this was one of the few products that doesn't irritate and works! I love that it's combined with hyaluronic acid, but it also absorbs into my skin quickly. I typically use it twice a day - morning, and after washing my face at night (if I'm not being too lazy.) I definitely used this in my soothing process after starting tretinoin just over a year ago. I think I started this before tret, to be honest, and it was one of the few (of SEVERAL) products that I kept in my skin care process. I like using it on my face and neck, but I have also rubbed it onto my shoulders, hands, arms, and elbows, to help keep them soft and moisturized. I generally use just under one dropper of it every time I use it and put it mainly on my face and neck, but there's usually enough left on my hands that I can rub it into my elbows and shoulders and still benefit from it. Like I said, this is a regular repurchase for me. I always make sure to have more in my "stock" whenever I notice I'm running low, because I love this and don't want to go without. It's my first step after washing my face. Sometimes I'll put more stuff on after, but this on its own is enough when you're not damaging your skin barrier. Esp outside of winter. (Winter and tret mean I have to use this stuff like 2x/day, but that's fine!) I've been so happy with this, I haven't even considered trying another brand of azelaic acid. Cos de Baha has great products, in my experience. Enjoy!

I have been using this product twice day (Morning and Night) for over a month. Here is a detailed review for those who are interested! ---------------------------- Performance- 1000000/10!!! - This product is absolutely amazing, especially for my Rosacea. It is incredibly hydrating and leaves a glowing shine behind on my skin. The redness has greatly reduced on my skin and altogether feels healthier. HIGHLY RECOMMEND FOR ROSACEA SUFFERERS! - I will note that this product is incredible hydrating for the skin. If you suffer with more dry skin, then this product is sure to help hydrate! If your skin type is more oily, I wouldn't recommend this product. But if you still want to use it, try using a smaller amount on your skin. ------------------- Consistency-8/10 - The serum is very light weight and breathable on my skin. It has a very smooth texture, not too oily and not too wet. It glides seamlessly with just a drop or two. - The only concerns I have are the stickiness and the fact it can harden and crystallize in the bottle. But these are easy fixes! - If you happen to struggle with stickiness, make sure that your face is damp (not wet). Damp skin is easier to penetrate than dry skin, this goes for any product on your skin! Simply mist your face with water or gently pat your face with a wet cloth before using the serum and make sure to rub it evenly across your skin. (When rubbing in any product, start from the center of your face and work your way out to the edges of your face.) - If you're struggling with the product crystallizing, just submerge the bottle in hot water for a few minutes, it will melt the crystals back to its serum form! --------------------- Ingredients- 10/10 - This product is PERFECT for Rosacea sufferers. I have looked through each ingredient in the bottle and did research to see if it is helpful or harmful. So this portion of the review will be in mind for those who suffer with Rosacea and sensitive skin. I've also taken the liberty to provide what the ingredient is and what it does. - Note: You can NOT buy Azeliac Acid above 10% without a prescription from a doctor. If you see any products labeled above 10% Azeliac Acid that is over the counter, it is most likely fake. ~Ingredient overview~ - Aloe Barbadensis Leaf Extract (Aloe Vera Leaf)- Anti-inflammatory, soothing, antioxidant, hydrating. - Azeliac Acid (Dicarboxylic Acid Molecule)- A rosacea sufferer's best friend! Anti-inflammatory, antioxidant, exfoliant, PH stabilizer, reduces pigmentation, antibacterial. - Panthenol (Vitamin B5)- Helps skin barrier, anti-inflammatory, soothing, gentle, reduces redness. - Niacinamide (Vitamin B3)- Helps skin barrier, anti-inflammatory, soothing, reduces redness, decreases sensitivity. - Sodium Hyaluronate (Sodium salt from Hyaluronic Acid)- Soothing, anti-inflammatory, moisturizing, healing properties. - Camellia Sinensis Leaf Extract (Tea leaf oil extract)- Soothing, calms skin, antioxidant, anti-inflammatory, antimicrobial. - Momordica charantia fruit extract (Bitter Melon extract)- Anti-inflammatory, reduces redness, antimicrobial, skin protection. - Sambucus Nigra Extract (Black Elderberry extract)- Soothing, antioxidant, anti-aging. - (The remaining ingredients are simply used to help the consistency of the product or the PH level. It does not improve or worsen rosacea) ------------------------ Value For Money- 10/10 This is a great product, especially for the money value. I still have plenty of product left after using it twice a day, every day, for over a month! ---------------------- All Together- 10/10!!! I HIGHLY recommend this product, especially if you have rosacea and/or dry skin. It's probably my favorite product I have in my skincare routine!

I bought this on a whim — I don’t think there were even any reviews at the time! — because I have really liked how Melazepam (also azelaic acid) helped my skin, but I can’t stand the texture more than a few times a week and only at night. I also wanted to add more niacinamide into my routine for general brightening. I’m so glad I did! I’ve been using this for two weeks every morning and it’s already made a big difference in the texture and clarity of my skin. I use this mornings only, after cleansing (Neogen real fresh green tea foaming cleanser), toning (Tony Moly wonder rice smoothing toner), and essence (Missha Time Revolution), but before my hydrating steps (COSRX hyaluronic acid + Mizon snail repair gel cream, sometimes a little propolis for fun). The texture is interesting — thin and slippery but also a little oily somehow, which I was worried about at first. I went back and forth but decided to use this before the HA so that the actives could be closer to my skin. It takes a minute to dry down, and but once it does my face feels comfortable and ready to be hydrated. Once I’ve added the HA and moisturizer, it’s the perfect, plump base for makeup! (Or no makeup, which is my usual look.) Even as the DC weather has started getting nasty-humid, this hasn’t made my skin any more oily around my nose or on my forehead. This doesn’t have the sting of Melazapam, or any other acid I’ve used, so I’m thinking of it more as a morning brightening booster. I still use Melazapam a few times a week at night, on nights I’m not using BHA/AHA. I’ve only changed one other thing in my skincare routine (*more on that in a minute), and in two weeks my skin is looking smoother with less redness... totally flake free (absorbing more moisture?)... and the closed comedones on more forehead I’ve been dealing with literally for years are going away! Plus I’ve had many fewer of the tiny little white dots (not milia... more like pustules, but teeny non-inflames ones) I had been getting from using something too rich for my skin (still can’t find a ceramide product that avoids that issue, even tho my dehydrated skin sucks up the Dr. Jart Ceramidin Liqiid like a a sponge, sigh...). This is a fantastic value for what it’s done! Will definitely repurchase. *The only other change I’ve made is adding COSRX snail 96 mucin power essence at night, over my HA and under my moisturizer. It’s really helped heal and strengthen my skin, and I recommend that as well! My face feels legit velvety at night after using it 😊

Azelaic acid is a must-have in my daily skincare routine, and this serum from Cos De BAHA has been one of my favorites for years. It has a lightweight consistency, absorbs well, and doesn't feel greasy at all. It works especially well whenever I get hormonal breakouts and has helped keep my skin looking clearer and brighter over time. I've also noticed a significant improvement in my post-inflammatory hyperpigmentation (PIH), with dark marks fading much faster. I rotate this with my Vitamin C serum, and the combination has kept my skin looking healthy, bright, and even-toned. The price is incredibly affordable for the quality, making it an excellent value. I'll definitely continue repurchasing! ❤️ Highly recommended!

I bought this hoping it will help calm my rosacea after reading a lot about it and checking reviews, unfortunately for me it didnt work and i had to stop using it, it iritated my rosacea more. Its absorbed pretty fast and in other areas of my face that dont have rosacea i felt more benefits like softer and brighter skin but it didnt work for my intended goal.

Okay so I actually bought this as a hail-mary after being told by my dermatologist that the only way to get rid of the PIE (that I've had for years) and the other dark spots is by paying a minimum of $380 or $700-smth for a SINGLE treatment, and I was obviously like SUPER against that cuz nobody in this day and age can willingly pay that much for smth like this, so I started doing a bit of research and found Azelaic acid was a good idea, so I bought this Umm so like it's almost creepy how well this works?? Like I'm kind of pissed that this existed the entire time, and I even put my bf onto this like last year (I forgot this product existed 😢) to go w/ his tretinoin treatment, but I never thought to try it myself even though it gave him crazy results 💔 Like it's actually insane. It soothed SO much irritation, worked great with my routine, feels nice under moisturiser, zero fragrance, and omg dude my skin is so happy with this on it's actually insane I apply it at night after using my toners and before my moisturiser. That is it. Did it four nights in a row and randomly everything's just BAM. GONE. Even the texture is annihilated too like omg bro this is insane Like I don't think y'all can understand how like amazed and confused I am but like I mean it works and it works WELL. Good Lord bro I'm writing this review like 3/4 weeks after my first use btw and the results have basically stayed the same w/ some more lightening of the darkest spots. Genuinely insane but like I said ts REALLY works😰 UPDATE: It's been around 3 months now and it generally keeps my skin even and smooth, I ADORE IT! The scarring is very minimal now, I'm so freaking grateful dude☹️!! Get this!!

I have moderate papulopustular rosacea, and with it comes the little white pore plugs that anyone within 3 feet can see under my makeup. It gave my skin a rough texture all over, especially on my nose and chin. These were very much like blackheads, only white and they stuck out of my pores and looked like little slivers if pulled out with tweezers. These were all over my face, but worse in some areas. I used salicylic acid for a long time to help keep the roughness to a minimum, but the plugs still existed and dug in their proverbial heels, refusing to go away. Even when I could get SOME of them out with those pore strips that promise to yank out all your blackheads, they would return in just a couple of days. (What I'm driving at is that these were more stubborn than your average blackhead. More...Sticky?). I had used Finacea for a while years ago, and loved what it did for my skin, but my insurance copay was almost $200 a tube and I couldn't afford to keep buying it every month. After Azelaic acid finally became available OTC years later I kept a watch out for for a new, affordable Azelaic acid product that would deliver the same results. I tried some products that had unfortunate filler ingredients like dimethicone, in excess. (Yes, I know there are some quality products that contain this ingredient, but as a main ingredient it makes for an unusable product that causes your makeup to ball up on your skin and, for me at least, causes more clogged pores). I was disappointed and disheartened and felt that I was doomed to a life of bad skin unless I was willing to fork over the dough every month for the Finacea. Then I found this product and read the ingredients and saw that there was NO DIMETHICONE and it got my attention. I decided to give it a try, and I'm really glad I did. This serum absorbs quickly into the skin, so much so that I need to use 3-4 drops instead of the 1-2 drops recommended on the bottle because I have trouble spreading it all over before my skin soaks it all up. I leave it on for a few minutes before putting my moisturizer on for max benefit, then apply my makeup like normal. This product doesn't cause my makeup to ball up at all since it absorbs immediately into skin. In the couple of months I've been using it, my skin feels so smooth, and all of those ugly white pore plug slivers are gone. I also have drastically fewer pustules that surface throughout the day from my rosacea. I keep touching my face because I can't believe that MY skin feels this smooth. I wish I had thought to take before-and-after pics to show other people, but I don't need them for myself. The change is drastic enough that I don't need the "before" pics to realize the difference. At first I did find that my skin responded best to this product if I used it only once a day, but after the first few weeks my skin loves it twice a day, and I have even better results. To sum it up, my skin feels and looks better than it has in years, and I'm glad to have found an affordable alternative to the expensive prescription. If it stays this price, I will continue to purchase again and again.

So, I've been battling cyclic acne since I was eleven. When I was 48 I was diagnosed with Rosacea. I am now almost 51. I waited a couple of months to write this review because I didn't know if it would continue working. Anyone who is dealing with Rosacea knows everything makes it worse. I was prescribed Metrogel. That made a huge difference but still had brake throughs from time to time when I would be stressed or had been in the sun too long. Or, didn't wash my face both morning and night. I do a lot of camping and I work outside a lot so this was always an issue. By the way time I was in my 20's I had lot trust in any product and didn't trust anything on my face. As I got older and moved to an area where the winters are extremely dry and cold my skin began to show real signs of wear and tear. I desperately needed a moisturizer but everything I tried caused horrible cysts that would last literally months they weren't normal acne. They were deep, painful and they spread like wildfire as I got older they began to cause scarring. Now I was dealing with cystic acne, dry skin, scarring and now wrinkles. I continued for years my research and desperate quest for something that I could use on my face along with the metrogel. One night after two glasses of wine I accidentally ordered this product. It was the most amazing accident I had ever committed in my life. I still get breakouts from time to time but they are normal tiny little pimples and they come and go within a week. My skin is actually soft and moisturized, the fine lines around my eyes, lips and chin are going away. At first using this product for the first week or so my skin did break out but I was determined to try to make this work because it felt so good on my skin I was able to use it without my eyeliner smearing and running because it was non oily it's soaked in beautifully. By the end of the first two weeks there was a dramatic difference in my skin even the scarring and redness from my rosacea was disappearing. I wash my face every morning and every night with liquid tar soap. After drying my face I apply the metrogel and allow that to dry. Then I apply this product all over my face and neck. This was the first winter that my lips did not crack open. The first winter my cheeks were not cracked and raw from the dry air. This product is nothing short of a miracle for me. So far this spring I have not noticed that it has caused sensitivity to the Sun any more than my skin already was considering my complexion is extremely fair. I hope this helps others out there. My life and self-confidence is dramatically affected and boosted because of this product. I pray to the good Lord above it never disappears off the market. I will be stalking up.

good

Cosmetic use.

I’ve noticed an immediate difference with my rosacea. Redness has massively reduced in days and my skin feels lovely. Great value for money.

Me encantó, desde que lo uso he notado que mi cara ya no se enrojece, soy de piel delicada y con el sol o con el frío o casi con cualquier cosa ya estoy como tomate, y la verdad me sorprendió, definitivamente lo volveré a comprar

頬の赤みと毛穴が気になっていたので購入しました❗️使い始めて2ヶ月目ですが、使う前よりも頬の赤みは引いてて毛穴も目立たなくなってます‼️最高です‼️👍
