    5.0 out of 5 stars Great!
    Reviewed in the United States on April 3, 2025
    Size: Travel Size - 0.17 Fl OzVerified Purchase
    I am absolutely impressed with this Boost Cream with Azelaic Acid! It has become a game-changer in my skincare routine. From the very first application, I noticed how lightweight and fast-absorbing it is, making it perfect for both morning and evening use.

    One of the standout benefits of this cream is how well it helps with redness and uneven skin tone. I struggle with occasional breakouts and mild rosacea, and after just a few weeks of use, my skin looks much calmer and more even. The azelaic acid works wonders at reducing inflammation, while also gently brightening my complexion.

    I also love that this cream provides great hydration without feeling heavy or greasy. It layers beautifully under makeup and doesn’t cause pilling, which is a huge plus for me. My skin feels smooth, soft, and well-balanced throughout the day.

    Another thing I appreciate is that it’s non-irritating—even for sensitive skin. Many active ingredients can be too harsh, but this cream is gentle yet effective, making it suitable for daily use.

    Overall, this is a must-have for anyone dealing with redness, acne-prone skin, or dullness. It’s a fantastic product that truly delivers results, and I will definitely keep repurchasing it! Highly recommend!

    Paula’s Choice is pretty expensive. Sometimes you can get cheap when it’s on sale at Ulta/Sephora. No scent but it does sting a bit. It does leave my skin smooth but it’s not for moisturizing. It helps with pores. And pretty effective. I’ve been using this and the naturium brand which is cheaper.

    4.0 out of 5 stars Works great and smells satisfying, but kind of expensive
    Reviewed in the United States on December 25, 2024
    Size: 1 Fl Oz (Pack of 1)Verified Purchase
    Very effective for redness and great for a gentle (at least as gentle as you can get) chemical exfoliant for acne or hyperpigmentation. It feels pretty great and smells medical/clean/chemically? which I don't know if I'm weird, but I like and doesn't peel unlike many other azelaic acids. Only problem is that you get a very small tube for 40 dollars and while it would be great if you used it for spot treating, if you use it on a lot of the face like me for my T-zone, it is pretty expensive. I used it sparingly (like once a week) and I'm almost out in about 4 months.

    Size: 1 Fl Oz (Pack of 1)Verified Purchase
    I feel like this product has potential. I’ve used it for 3 days and it didn’t break out my skin. However, it made my skin feel like it was burning and it stings. I wanted to wait at least a week to see if the feeling would subside but it’s uncomfortable. I think it may be too strong for my skin.

    Size: Travel Size - 0.17 Fl OzVerified Purchase
    I’ve spent the last 30 years of my 42 on this planet frantically covering up my skin. Going without makeup or even going with something as light as a BB product was unfathomable to me. I have it all: rosacea, large pores, acne, ruddy undertones… I’m Polish and Spanish, so I’m really pale but my face is really red. THIS STUFF… changed all of that. I saw someone on Reddit recommend this for rosacea, and after growing tired of seeing a tomato in the mirror every time I took my makeup off, I tried this. Within one day? A small difference. Within two weeks? I’m ready to go without foundation. For real. The photo I’m attaching is after 10 days, with a tiny bit of tinted moisturizer and blush over my skin. A miracle. I wish I could go back in time and give this stuff to teenaged me.

    1.0 out of 5 stars Not good for sensitive skin
    Reviewed in the United States on December 15, 2024
    Size: Travel Size - 0.17 Fl OzVerified Purchase
    I gave this product a chance because my skin has done well before using azelaic acid and salicylic acid separately. I tried this product to see if it would help relieve my acne and lighten my PIE but it instead broke me out with large, painful cystic acne. I think the combination of mixing the 2 acids into one product irritated my skin.

    This reaction was only after one use. I was planning to use it again to see if it subsided, but after reading the reviews on the Paula’s Choice website, it seems like this is a common side effect for some people, and using it repeatedly only makes it worse. I won’t be using it again unfortunately and will go back to using these 2 acids separately.

    It is more expensive than what was listed on the original website! Unfortunately, it didn’t work for me, which made it feel like a waste of money. I guess results can vary from person to person, but I was really hoping for a better experience. Overall, I wouldn’t recommend it based on my experience.
