【Brand Name】 Anua / Anua 【Category】 Serum 【Product Name】 Azelaic Acid 15 Intense Calming Serum Purchased in a Qoo10 lucky bag, I used a total of 6 drops over 2 days, but I've decided it doesn't suit my current skin type, so I'm putting it up for sale. The dropper tip has not touched my skin directly. Although it's hardly been used, please refrain from purchasing if you are overly concerned about this. Please note that I have already discarded the box.
