Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.

- Reviewed in the United States on April 3, 2025Size: Travel Size - 0.17 Fl OzVerified PurchaseI 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!
- Reviewed in the United States on May 6, 2025Size: Travel Size - 0.17 Fl OzVerified PurchaseStrong and I'm seeing differences in my skin & pores in a week or two! Scent is very light and I dont mind at all but also keep in mind i love fragrance. I heard your skin will feeel irritated or itchy for the first 2-3 weeks but its not too horrible
- Reviewed in the United States on May 6, 2025Size: 1 Fl Oz (Pack of 1)Verified PurchaseThis has really saved my skin. I get really bad hormonal breakouts occasionally and have tried almost everything to get rid of the hyperpigmentation/acne scars. I’ve used Paula’s Choice BHA and other products which have done wonders on my skin. I finally decided to give this a try after seeing reviews on Sephora. I kid you not, within the first two days I could see a difference. It was really noticeable within a week of use. It’s my holy grail now. It’s perfect for sensitive skin but of course always patch test. Definitely give this product a try. I have sensitive and oily skin but this has really done wonders! The scaring was really worse than the first photo.

- Reviewed in the United States on December 25, 2024Size: 1 Fl Oz (Pack of 1)Verified PurchaseVery 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.
- Reviewed in the United States on April 29, 2025Size: 1 Fl Oz (Pack of 1)Verified PurchaseI have sent days and days looking for a product that would take away my red/flushing face. I quit drinking and smoking months ago and that helped a little but never fully got rid of the red face. Used this product and honestly within 20 mins, felt like I had my old face back. I don't go anywhere without this product now. Some people say it's pricey but it is worth every penny in my opinion!!
- Reviewed in the United States on March 17, 2025Size: 1 Fl Oz (Pack of 1)Verified PurchaseI 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.
- Reviewed in the United States on April 23, 2025Size: 1 Fl Oz (Pack of 1)Verified PurchaseDon’t use too much or it will irritate your skin. Otherwise it improves the clarity of my skin.
- Reviewed in the United States on December 15, 2024Size: Travel Size - 0.17 Fl OzVerified PurchaseI 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.

1.0 out of 5 stars Unsatisfied
Size: 1 Fl Oz (Pack of 1)Verified PurchaseIt 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.
- Avanti MalusteReviewed in India on October 16, 2020
5.0 out of 5 stars Just what my skin needed
Size: 1 Fl Oz (Pack of 1)Verified PurchaseI have oily skin and get hormonal break outs and maskne. I mix this with my moisturizer and it’s honestly helped calm my skin down SO MUCH. I find my complexion has improved too. And I’ve been using it less than a month! Don’t forget to wear sunscreen if you use it in the day like I do!
