Gentle cleanser for dry and sensitive skin.
Style: Tolerance Daily Foaming Facial Cleanser, Style: Tolerance Daily Foaming Facial Cleanser
I have dry and sensitive skin, and this cleanser has worked very well for me. It is very gentle on the skin and has not caused any irritation.
The texture is light and foamy, it spreads easily across the face and rinses off without leaving any residue. After using it, my skin feels clean, soft, and comfortable, without any tightness.
The size is quite large, which I find great because it lasts a long time with daily use.
Overall, a simple but very pleasant cleanser for sensitive skin.

Gentle Yet Effective—Perfect for Redness and Sensitive Skin
I’ve been really impressed with this Anua Azelaic Acid serum—it’s one of those products that feels gentle but still delivers noticeable results. The formula is lightweight and absorbs quickly, leaving no sticky or heavy feeling behind, which makes it easy to layer with the rest of my skincare.
What stands out most is how soothing it is. The 10% azelaic acid helps calm redness and irritation while still being mild enough for sensitive skin. Combined with multiple types of hyaluronic acid, it keeps my skin hydrated and balanced instead of dry or tight. 
Over time, I noticed my skin tone looking more even and less inflamed, especially in areas prone to breakouts or redness. It’s a great option if you want something that targets multiple concerns—like texture, redness, and hydration—without being too harsh.
Overall, this is a fantastic serum for anyone dealing with sensitive or reactive skin. It’s effective, easy to use, and feels like a high-quality addition to a daily routine. I’ll definitely keep repurchasing.

Totally worth it!!
So I have combination skin with a tendency toward closed comedones and I decided to try this product because I heard that azelaic acid helps with closed comedones. Honestly, I didn’t have very high expectations because my closed comedones have been very stubborn. I was already using the COSRX BHA before introducing this product, but it worked very slowly, so I wasn’t really getting the results I wanted from that product alone. Let me tell you that once I introduced this product, I finally started seeing the results I was looking for. I have noticed that my closed comedones have been resolving way faster than when I was only using the BHA and my skin also feels softer and overall looks healthier. I also want to mention that even though I don’t get inflamed breakouts very often, when I do get one, I feel like this product helps it calm down and go away much faster. I did start incorporating it slowly, and I highly recommend that anyone who wants to start using this product do the same and not rush into using it every day right away. Despite that, I personally haven’t had any issues with irritation at all and I actually find it very soothing, but you always need to be careful when adding new actives to your routine. I am currently using this product 4-5 days a week, once a day, and on the days I do not use it, I use my BHA instead. I also find that this product lasts a long time, since you only need like five drops for the entire face and the consistency is very watery. I’ve been using it for around two months, and there is still plenty left. Overall, I really recommend this product because it has helped me a lot, and while I am not sure if this alone would be enough to treat closed comedones, I would definitely say it is a great complement to other treatments.

Changed my skin in 5 days
This stuff transformed my skin in 5 days! I’ve had issues with random breakouts and redness ever since I turned 40 and have had difficulty finding a product that actually helps those issues. I incorporated this product into my daily routine for the last 5 days and my skin is clear, moisturized, super soft and redness/breakout free. I use this after washing my face and applying toner; I use just enough to cover my face as a little goes a long way. It has a very loose, almost oily consistency but spreads easily and doesn’t make your skin feel greasy at all. Once it’s absorbed into my skin, I apply my moisturizer. I would definitely recommend this to anyone with skin redness and dryness, it’s a game changer!

I think this will help my rosacea redness!
Update: after using this 2 months, I will be reordering. The rosacea redness to my cheeks and nose have drastically reduced. I use it every other day. I tried a routine of on alternating mornings using vitamin c one day and this Anua azelaic acid the next. Cleanse, tone, azelaic acid, and then whatever I'm doing next (including SPF if I'm going outside). I don't use it at night, preferring a different routine with actives at night.
I don't use the hypochlorous acid on my face very often at all now so the Anua is doing the work of hydrating and helping calm my skin.
Note that I have aging skin that likely could be prone to dryness but I am meticulous about my skincare so my skin isn't dry - so though they advertise it's for blemish-prone skin, I use it for rosacea redness, and alternating plus hydrating before and after azelaic acid is what works for my skin.
------
The first time I tried this over my entire face, it made my face immediately red so I considered returning it. However, I had used other serums and thought maybe it was just too much at once for my rosacea-prone skin, and that I used too much as well. (I will add that I did a small patch test along my jawbone and let that absorb for hours - always do a patch test of an unfamiliar product!)
After a couple of days, I tried it again, and I am impressed! This time, I hadn't used my tretinoin the night before - since I just went up in strength, my skin has been reactive. This time I cleansed my face using Thayer's milk cleanser, which is very soothing, and in fact is one of the only non-Korean beauty products in my skincare routine. Then I used my TirTir milky toner. I waited 5-10 minutes, then I applied just a little bit of this Anua Azelaic Acid over my entire face.
I was very surprised that there was no burning or irritation. And also surprised that a few minutes later some of the redness on my cheeks were calmed down--nothing earthshaking but there was a slight difference.
I let that absorb/sit for about 10 minutes and then I applied my Cosrx ceramide booster serum, which is very hydrating, and after letting that absorb for 5 or 10 minutes, I applied my Cosrx snail music to further hydrate. I'll be applying another moisturizer to seal it all in.
I tried it again the next day and had similar results - again, not using my tret the night before or the C the same morning.
This likely, at least at first, won't be a part of my daily routine as I think it could be too strong for my skin along with the other actives I use. For example, I won't use it when I apply my vitamin C until I lower the strength or until my skin is used to the azelaic acid, and I definitely wouldn't use it right before or right after tretinoin. I will do as they suggest and at first use it maybe 2x a week, so on weekends when I don't use my tretinoin or vitamin c, I will use this Anua azelaic acid. After doing this for a couple weeks, I may experiment and start using it more often --perhaps alternating this and my vitamin c since my vitamin c is really strong. As well I may consider lowering my vitamin c strength, and go back to the lower strength tret. (Update: I was out of town so I took a 4-day break from tret and vitamin c and tried this every morning after toning with hypochlorous acid (I let the HA dry completely first), and this didn't irritate my skin at all, and in fact, helped the redness. I am going to find a way to add it to my routine maybe by alternating days using this and vitamin c.)
This is fragrance free, which is a must for me. The consistency is thin but not overly watery - glides on easily. I bought mine on Spring Sale so I'm happy about that.
I will also add that I use Metrocream, and hypochlorous acid spray (Prequel) on my skin a few times a week and that helps the redness as well.
It's an experimental process to find what will be right for my rosacea and aging skin.
I am hoping with regular use my redness will calm even more as I hate the flushing across my cheeks and nose that I've dealt with for many years.
I'm hopeful!
