Ratings & Reviews

This product is amazing, a game changer indeed!


WOW -- I just got this product a week ago, and have been VERY impressed with the results in such a short period of time. With consistent daily use and at night, I am starting to notice that the bumpy texture (milia?) of the skin on my chin -- due to sun damage and aging -- has already become smoother and more healthy looking. I am in my 60s, so I never thought there would be any hope for smoothing out the texture of aging skin like this. I also have developed sensitive skin in later years, so I have to be careful with my products. I have been using prescription Retin-A for years -- but it never did anything like this for the bumpy texture. I should add that it seems to fade some red areas, due to acne and scars. Again, I have only been using it for a week -- but was compelled to write, if only to say "Thank you, Paula!" Wonderful addition to my PC products.

The Best!!!


I could see a difference within days of beginning with it. It is a white cream but it just disappears into the skin without any effort and leaves no white cast. I had post-acne marks, but within 2 weeks of using Azelaic Acid, they are fading away nicely. However, I did break out at the beginning of using it. But I was using the 2% BHA and I found this was tipping the scales of my skin tolerance, as the Azelaic Acid booster also has BHA in it; not a lot, but enough to make a difference on my skin. So I have stopped the 2% BHA. I only use the Azelaic Acid booster in my daytime routine. At night, I use the 4% BHA. It seems to be working great. I might begin to put BHA back into my daytime routine again and begin with the 1% BHA. The combination of Azelaic Acid and 10% Niacinamide booster used together mean my skin is looking the best it has for a long time. Please never stop making the Azelaic Acid booster!

I have been using Paula's Choice products for a long time, because they're the only thing that can keep my skin in check. However, I've never been so compelled to write a review until now. First, let me state that I have mild to moderate Rosacea, so reducing redness is a constant struggle for me, and something that I understand will likely never go away. PC's CLEAR Pore Normalizing Cleanser keeps the pimples Rosacea causes away, but the redness is always there. However, this product has significantly reduced the redness caused by my Rosacea! It's almost too good to be true! My skin has never looked so even and calm. Also, this product applies very nicely to the skin, and absorbs easily. The only downside is that it does make my skin a little itchy, but that feeling goes away within 20 minutes of application. However, I will deal with that tiny inconvenience for the amazing results I get. Please never stop making this product!

Makes my skin tone very even


I use it twice daily. In the morning with 2% salysilic acid and 5% benzoyl peroxide (I put it on after those two). I follow with sunscreen. At night I use it alone. I had patches of mild rosacea but not now. I'll continue to use this.




Absolutely Awesome


I am 55 years old and have a medium tan complexion as I am half black and half white. Unfortunately, I have accumulated some sun damage due to growing up by the beach and running track in my youth. I have worn sunscreen faithfully since around the age of 27 due to Paula, of course. I've been a fan of hers since warnings about blue eye shadow. These dark sports were really starting to bother me. However, I am severely allergic to hydroquinone, so I was excited to try the azelaic acid. I has worked wonders, and I actually saw improvement in about a week. I will note that I also began using her Clinical 1% Retin A, so I'm fairly sure this helped the process along as well. Lasly, I would like to add that Paula's Choice are an excellent value for the money, and my skin looks wonderul. Most people say I look 10 plus years than I am.

Very Good Product


I have been using this product for 2 months. I did not see drastic overnight results, but I have noticed that my skin is smoother. I also use a little less foundation and it blends better than before. I use this twice daily after cleansing and toner, by itself, and under HQ (because I have dark spots), then I apply moisturizer (one with SPF in the mornings). For those of you fighting dark spots, like me, I have not see a difference yet, but it may still be too early. I do like the results on the texture of my skin so I will purchase again. In case it matters, I am a 52 Asian with combination skin with dark spots.

You have to get this product!


This is a miracle in a tube! I just ordered it and have been using it for 5 days. I already see a huge difference! I've had acne since I was not even 12 years old (I'm now 59) and I've used Paula's Choice for many years now. It has helped my skin tremendously, slowly erasing deep acne scars. But this, this is even better than anything I've tried! Here's my routine: Morning: Calm Redness relief cleanser, 2% BHA, Calm Redness relief serum, 10% Azalaic booster, Resist eye cream. I used to put a thick coat of foundation to cover my skin but not anymore, starting with yesterday. I use the Super Light Wrinkle defense, which has a slight tint. I put a bit of concealer and powder to finish up. My skin stays matte (unheard of until now!) all day and my skin looks unbelievably nice and healthy! Night: Perfectly Balanced Foaming cleanser, 2% BHA, Calm Redness relief serum, 10% Azalaic booster, Calm Relief moisturizer. One a week, I use the 4% BHA and the 10% AHA with the Resist Intensive Wrinkle Repair retinol on top. When I did this treatment two days ago, I also put the Azalaic booster to finish off. I keep that all night and wake up to a wrinkle-free skin. Amazing!

I am a long time user of Paula's products, and love the BHA gel, which I use regularly. I switched from benzoyl peroxide to this booster, and I get acne treatment without all the side effects of BP. Even the acne scars on my chin are lightening and look like they are going away. I also use this booster on the rest of my face where I don't get acne, and my skin glows! This product has been an unexpected miracle for my skin.

Game Changer


This has been a real game changer for me. I use twice a day mixed with my retinol serum and it has changed the texture of my skin-now it feels so smooth! It has also evened out my skin and I actually feel like I can do the "no makeup" thing and look good. I'm 52 so that's a pretty big deal in my book! I've gone on auto replenishment so I don't run out. The tube lasts a good while because you only use a very small amount at a time. I've used Paula's Choice for about two years and already loved how my skin has improved but this one addition to my routine really upped my results. Thanks Paula!!




Ditto, what everyone says


Wonderful texture and the product is protected well from light and our dirty little fingers! I didn't know what the cream/gel thing was all about so I called the company to ask what that meant. The very helpful lady said it comes out kind of "puffy"! Well, that was intriguing so I ordered two. Yes, she's right, the product comes out puffy, that's the best way to describe it. In practical terms it applies evenly and seems to do a good job on my combo/sensitive/rosacea skin, dries quickly if you don't use too much, and doesn't pill up under liquid makeup. If you choose to use a powder foundation, this will be a good layer underneath the powder. The only things I'd like to see about the application are "how much to use" and "can it be used around the eyes." I ordered two more when the PC Labor Day sale started. Paula, another winner! Thank you so much.
