Azelaic Acid for Face Serum 15 percent Niacinamide Vitamin C BALANCING ESSENCE AZ 1 Fl Oz MADE IN JAPAN

I really liked this azelaic acid serum and will likely repurchase. I found it to really help refine my skin and help prevent it becoming so congested. I have a tendency to get blocked pores and sebum plugs, and this seemed to really help make my skin overall smoother and brighter. I feel it helps if your skin tends toward keratin buildup and overall congestion.I found this really hydrating and not at all sticky, but I live in a really dry climate and few things remain sticky throughout the day. It absorbs quickly into the skin and I had no issues with pilling or how it sat under makeup or other skin care items. I like that it's unscented, as that is my preference for skin care. I didn't detect any smell at all from it.I think this one is great value for money and it lasted me several months when I used it most days (either morning or evening, depending on what else was in my routine)

I’ve been using this serum for a few weeks now, and I’m really impressed. The 15% azelaic acid feels strong enough to make a difference but still gentle on my sensitive skin — no stinging or irritation. The combination with niacinamide and vitamin C makes this a powerhouse for dullness and uneven texture.I’ve noticed less redness around my nose and chin, and my skin looks a bit more even and calm overall. The texture of the serum is lightweight, absorbs quickly, and layers nicely with my moisturizer and sunscreen. A little goes a long way, and the fact that it’s made in Japan and fragrance-free makes me feel even better about the quality.If you’re looking for something to help with tone, brightness, and balancing oil without being too harsh, this is a great option.

It helps a LOT with redness. No results with skin breakouts or pores. I will keep ordering

Easy to use but results will come in time. Takes anywhere from 4 to 6 weeks.

Went to Japan to buy beauty supplies and came home planning on just buying this again after not finding anything better/cheaper. Great value for the money. I have sensitive skin and the lack of scent is really nice.

I’ve been using it since the day I got it along with another products like tranexamic acidand it’s been helping me a lot, my skin now.I’ll update if I remember

Great product, my red spots are gone! I use it twice a day, will buy it again!

Very misleadingThis has Potassium Azeloyl DiglycinateThis is a derivative of azelaic acid. It’s a water-soluble salt formed from azelaic acid and glycine. While it has similar properties (e.g., skin brightening, anti-inflammatory, sebum regulation), it is not the same as azelaic acid in structure or potency.The product claims 15% azelaic acid, and only includes Potassium Azeloyl Diglycinate, that claim is misleading unless clarified. A 15% concentration of the derivative does not equate to 15% pure azelaic acid.
