"...The tube is small, but I think there's enough to get a sense of whether or not the product would work for someone...." Read more

"The size is very small because it's a SAMPLE (Boost), and same price as another I usually buy that is literally 1/2 the size...." Read more

"...Travel size is suuuper tiny, but nice for your purse or on a trip." Read more

    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.

    I have acne. It’s mild now. four months ago (and for the last two years before that), my face was a swollen, blotchy mess much of the time.
    Then I started using this, and I took a photo of my face every day for all that time to see the progress, because here’s the thing about azelaic acid: It can behave like a (safe, non-resistance-forming) antibiotic for your skin, but it is very slow to show results. As I review my photos, I can see that for about two months of using this I didn’t really have a noticeable improvement. But then, after that, I can see a gradual improvement. By month four, my skin is so much better that I don’t think I’ll ever stop using this.

    No, my skin isn’t perfect. I have redness on my nose that appears to have resulted from acne, and I still get small zits here and there, but my days of deep, swollen, achy, itchy zits that last for weeks are gone. I haven’t had one like that in well, about two or three months.

    If you’re considering getting this, but you’re put off by the price, I get you. I thought so too. But this bottle lasts about two months if you use it twice a day, because you really don’t use a lot. So it isn’t as bad as it seems.

    I use this product as the very last in my night time skin routine — and I use it anywhere I can feel I will have a zit, anywhere I have one, and where I’ve recently had one — but I also just put a thin amount in the places I know have a tendency to breakout.

    I also use it in the morning, but then only a very small amount beneath sunscreen and makeup. It has a tendency to pill unfortunately, so you’ll need to be particularly careful with it. In the daytime use an extra tiny little bit of it. Moisturize the areas it will be on extra, let the moisturizer sink in, apply this, and gently pat products on top, don’t rub. For real, don’t rub or it’ll come right off (you can rub it in when applying it, just not once its been on your skin for more than about a minute).

    It can be a bit itchy. In my case its really only itchy when its on too thickly. This also gets better over time.

    I’ve found other spot treatments to be too harsh and drying, and/or not work well. This isn’t the fastest spot treatment, but if you can be patient, this is just awesome.

    I have red face, this really helps. Good texture, pretty thick. I put it on almost last before my moisturizer. You’ll want to patch test because it can sting since it’s acid. No negative effects and I combine with moisturizer and toner in the mornings. Much more affordable than other products that claim to do the same thing. Slightly weird smell

    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.

    I am beyond disappointed by this product. After reading the reviews I expected this to remove red spots/acne marks from my skin. I didn't see any noticeable changes at the start so I waited... and waited... aaaand waited.

    It has been a month and a half and my skin still looks the same. I paid a ridiculous amount of money for a miniscule fragment of a supposedly effective treatment and let it slide, but enough is enough.

    I'm never buying this product (or any of Paula's Choice products for that matter) ever again.
