The Science-Backed Benefits of Azelaic Acid

Azelaic acid benefits extend far beyond basic skincare, offering clinically-proven results for multiple skin concerns. This naturally occurring ingredient has become a dermatologist favourite for its unique ability to target redness, inflammation, and uneven skin tone whilst being gentle enough for sensitive, rosacea-prone skin. Unlike harsh treatments, azelaic acid works through multiple pathways to improve skin health. Its anti-inflammatory properties help reduce persistent redness, whilst its gentle exfoliating action evens skin tone without irritation. Clinical studies show that 10% azelaic acid formulations deliver optimal results, making it an ideal choice for those seeking effective yet gentle skincare solutions.

    Rosacea Relief

    Azealic Acid doesn't get enough time in the spotlight! I'm obsessed with this product and use it religiously for how amazing it makes my skin look. I have mild rosacea, and pale skin that easily reddens. Not only does the Azealaic Acid Serum keep my rosacea at bay and redness to a minimum, but it also does wonders for my skin texture. Can't recommend this product enough. Thank you INKEY! <3

    Love and have repurchased every month for a year now!

    This product is what has helped my acne and perioral dermatitis go away for one, which is why I give it 5 stars off the bat, but also the inkey list customer service team deserves another star they are so on top of it. Overall great company with products that deliver realistic and sustainable results. My acne is gone now but using this consistently twice a day has helped keep my skin happy. Love love love! Wish it was still at Sephora though I’m happy to order it

    Works for redness

    Really loving this product, it’s helping my redness while smoothing and brightening. I started using it in the morning instead of vitamin c and I use retinol at night. I don’t love the application because it goes on matte and feels a little dry on my already dry skin. I just go heavy on the moisturizer and the benefits are worth it
