What it is
Azepair Serum is a milky-textured treatment serum with 5 percent azelaic acid derived from sunflower seeds. It targets uneven pore texture, sebum concerns, and translucency, and pairs the azelaic acid with NMN, niacinamide, cica, and ceramides. The 28mL formula is free of alcohol, parabens, silicones, and artificial colorants.
Why it's different
A high 5 percent azelaic acid works on rough texture, pores, and clarity.
NMN, niacinamide, and cica support smoother, calmer, more translucent-looking skin.
A free-from formula, without alcohol, parabens, silicones, or colorants, suits reactive skin.
Key ingredients
Azelaic acid (5%): targets pores, texture, and clarity
NMN: supports skin vitality and translucency
Niacinamide: helps keep skin conditioned
How to use
1. After cleansing, prep skin with toner.
2. Take an appropriate amount on your palms and spread over the face.
3. Press gently with your palms to help it absorb. Use sunscreen in the day.

What our customers are saying
I was looking for a serum containing azelaic acid and purchased this. I've been concerned about the visibility of my pores, including my strawberry nose, for years. I've only used it a few times so I haven't seen any results yet, but it's not sticky and works well. I bought it online this time, but it seems to be available at drugstores, so if it works, I'll be able to buy it there in the future.
I think the price is reasonable. It spreads easily and feels moisturizing. I was a little concerned about the smell, but after applying it, it didn't bother me as much. I'm hoping it will change my skin.
I switched from my long-time favorite azelaic acid serum to this one. It might be really good...it seems to be working. It depends on the condition of my skin, but I did experience a slight tingling sensation (not quite that intense, but still quite subtle), but I think that might be why it's working, so I'm continuing to use it. It's in emulsion form, and it absorbs incredibly well into the skin. It's very moisturizing. P.S. I really love this product, but after using it, I ended up with a ton of acne. I use it on my whole face, but only the lower half is covered in acne, so I'm not sure if this product is the cause, but I'm taking a break just to be sure. I really liked it, so it's really sad, and I'll try using it again once things have settled down.
I was worried about my rough skin, so I bought this. It absorbs smoothly into my skin and doesn't feel sticky. I always used to get rough skin before my period, but since I started using this product, my skin has gotten less rough! I'm on my fourth bottle now! I highly recommend it!
I was attracted by the appearance, and although I wasn't sure about the ingredients, I bought it because it looked good, was reasonably priced, and was a Korean cosmetic made in Japan. My initial impression was that, although I'm not sure what it's good for, it feels good to use and looks good. I've been using it for almost two months now and have found some great points, so I'd like to share my review. It's helped me get rid of my acne. I looked up azelaic acid and found that it's good for acne. I thought so, but periodically I get these big, red, swollen bumps that are more like tumors than just pimples. Come to think of it, I haven't had any recently. It's winter, and chocolate doesn't melt, so I keep picking at it. I sometimes get constipated, but I haven't had any lately. I usually don't buy repeat products because I like to use a variety of products, but I thought this one might be worth continuing to use. My son has severe acne, so I bought it for him. He's currently using a different brand's dropper, but he's clumsy and finds it difficult to use. The pump makes it easy, so I'm going to have him try this one. This is my third purchase. I get tired of it easily, so this is the first time I've ever experienced anything like this. My son's acne has really disappeared. He's in adolescence, so it's hard to completely eliminate it, but it has reduced significantly. This is my fourth time buying it.
