I’ve been using the Anua Azelaic Acid 10% serum for over 2 months now, and I’m seriously impressed. I have sensitive, acne-prone skin, and this serum never irritated my skin or caused breakouts — which is really rare for me.The texture is super lightweight, absorbs fast, and works well under other products. I use it almost every day, and my skin feels smoother, less red, and more even overall. It’s also helped calm down small pimples without drying out my skin.The bottle also lasts a long time — I’m only halfway through even after more than two months of regular use. It came completely full when I received it, and the packaging feels high quality too.I honestly have nothing bad to say about this serum. I’ll definitely be repurchasing. If you have sensitive or acne-prone skin and want something gentle but effective, I really recommend this.
