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!

Works Great but the price is rising!
Anua Azelaic Acid is a very good serum. Both my daughter and I use it regularly. My daughter has severe rosacea, and this has helped calm her skin significantly her redness is almost gone. For me, it has also made a noticeable difference by reducing redness and giving my skin a healthy glow. We both use it at night, and it’s definitely very soothing and calming. The formula is gentle, lightweight, and works really well for sensitive skin without causing irritation.
However, the only downside is the price, it seems to have increased quite a bit recently, which is concerning. I bought a couple during Amazon Prime Day, which worked out really well. For a relatively simple azelaic acid serum, the price increase feels a bit steep.
If the price continues to rise, I may need to look for a more budget-friendly alternative. Otherwise, it’s a really great serum that delivers great results.

DERM APPROVED!
I am obsessed with this product!! This feels very luxurious on my skin and does not pill like other products I have had in the past. I have noticed a significant improvement in the background redness in my skin. As someone who works in derm and values good ingredients and products that actually work... I can confidently say that this is the best OTC azelaic acid product I have tried out. It sits very nicely under my moisturizer and does not dehydrate my skin like other azelaic acid products have done in the past. HIGHLY RECOMMEND

A Game Changer for Sensitive Skin
I use this serum every single day, and it has become one of the most important products in my skincare routine. I have very sensitive skin and cannot tolerate stronger active ingredients such as retinol or high-strength acids, so finding something effective but gentle has been incredibly important.
This serum has helped calm redness, reduce inflammation, and noticeably improve my skin’s overall appearance and comfort. After dealing with a prolonged inflammatory skin condition, this product made a significant difference and helped restore my skin barrier.
The formula feels soothing, hydrating, and non-irritating. If you have sensitive or reactive skin and are looking for a gentle product to help with redness and uneven texture, I highly recommend giving this serum a try.

Perfect for Acne-Prone Skin!
This serum has honestly been a great addition to my routine for redness and post-acne marks. The texture is lightweight, hydrating, and doesn’t feel sticky or heavy on my oily/acne-prone skin.
I have sensitive skin with a focus on barrier protection, and this didn’t irritate my skin at all. It layers beautifully with the rest of my skincare and leaves my skin looking calmer and smoother over time. AND, it doesn’t have a smell!!
Definitely one of my favorite azelaic acid serums I’ve tried.
