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)

This is so hard to find a 15% strength in OTC! It is less expensive than my copay for the prescription my dermatologist wrote. I was thrilled to find it. It is made in Japan and it a simple serum which I combine with vitamin C serum at my doctor’s suggestion. They absorb quickly and then I top with a lightweight moisturizer. This helps my rosacea and my aging skin. There’s no better value. I’ve just ordered my third bottle.

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

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.

I bought this product a couple months ago because of the higher percentage of azelaic acid. Other brands that I have used in the past have kept my oily skin shine free, even on the hottest days, and have helped clear up any random breakouts pretty much overnight.I’ve used this brand all summer, and my skin would appear oily within an hour. It also hasn’t helped clear any of my breakouts, leading me to believe that this doesn’t actually contain 15% strength acid.I gave it three stars because it hasn’t caused me to have any extra break outs, or irritated my skin, but I will probably stick with the other brands that I have used in the past.

This is my second time purchasing this serum and I love it. It has done wonders for my face!

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.

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.
