- The post was made 12 hoursAnua azelaic acid I had heard a lot about azelaic acid both on social media and from dermatologists, who often recommend it to even out skin tone and soothe the skin. I was initially quite skeptical, but now I have almost used up the entire bottle and am pleasantly surprised. The serum works very well with most active ingredients, such as vitamin C and retinol, provided the skin tolerates it. The texture is light, absorbs quickly, and works well in a skincare routine without peeling or pilling with other products. If you want to start using azelaic acid, I think this is a really good option. It is a well-formulated product that is easy to combine with other products, and I would definitely recommend it over many other azelaic acid serums I have tried. #kbeautysummer #anua #acelicazid #azelinsyra #kbeauty1 product in post8 views
