I was looking for Dalba's azelaic acid at Suzykirei, but it didn't seem to be available in store, so the sales associate recommended this one. I've been using it for about two weeks, and so far I haven't noticed any noticeable changes. I haven't had any skin problems, and it's reassuring that it's non-irritating, but I haven't noticed any effect on my pores. I'm also concerned that the liquid is a little hard to get out, and I can only use a small amount at a time. I may need to increase the amount or use it for a longer period to see any effect on my pores. I don't plan on repurchasing.
I saw this in the store and was intrigued, so I bought it. I mixed one drop of this with my serum and applied it, then applied azelaic acid cream, and it made my skin feel a little tight when I went to bed. The next morning, it didn't feel much different than usual. Because of this, I had to find a cream to use on the days I applied it, so I only used it on a limited number of days.
I bought this because I was concerned about my pores and dullness, but after using it for a while, I feel like my skin has become smoother. It stings a little, but once you get used to it, it's no problem!
I have inner dryness and my skin tends to get oily easily, but this is perfect for my dry skin! It also helps prevent acne, so I'd like to buy it again.
I bought it on Rakuten Ichiba. It has a watery texture and is not sticky, so it's easy to use even in the morning!
