Why is it different?
A unique leave-on formula that’s gentle enough for daily use on all skin types. Exfoliates dead skin cells while clearing pores for a more even, radiant tone, plus visibly reduces fine lines and wrinkles to reveal remarkably smoother, younger-looking skin.

This exfoliant has an optimal pH range of 3.2–3.8.

What does it do?
Skin becomes dull, dry and congested when dead skin cells build up on its surface. Beta hydroxy acid (BHA, also known as salicylic acid) mimics the natural exfoliation process of younger skin by helping it shed extra layers while unclogging and clearing pores.
How to use
Apply once or twice daily after cleansing and/or toning. Lightly soak a cotton pad and apply over the entire face, including the eye area (avoid lash line and eyelids). Do not rinse. For daytime, follow with a broad-spectrum sunscreen rated SPF 30 or greater.

Ratings & Reviews

I'm so glad I found this!


I originally just purchased a sample so if it didn't work I wouldn't be with yet another product that I wasted money on. I was skeptical of the reviews because I have been having some weird hormonal breakouts lately and I was doubtful it will help. Well, this product has helped me within a few days. I am trying to watch my diet and drink tons of water but the product helped calm my skin down. The redness has subsided and the bumps on my skin shrunk. I am experiencing some peeling but nothing too extreme. My pores seem less visible too! Just when I felt nothing was working this product saved me! I ended up purchasing a full bottle before my trial size runs out. I have only been applying in the evening. Thank you!!!

Almost like a moisturizer on my dry skin


I got a travel size of this on a special. I recently had laser treatment on my face, and with the removal of that leathery old lizard skin, my skin is now more sensitive to AHA . This product used after my toner, feels like it could almost replace all the other steps, my skin feels so soft and calm. I also love my AHA products, but this one seems to be better for the skin on my face and I now use the AHA on my decolletage instead.

Where are those faithful blackheads?


While I have been very lucky to have "good" skin my entire life (not a sun-worshipper), I have always had blackheads on my nose. I've tried so many things. Masks, Retin-A, those peel-off strips. Anything that I read about in a magazine or an internet article, I bought it and never had any reduction in blackheads (which really show on pale skin). Well, I was having problems with small bumps on my forehead (not red, just flesh-colored) and after doing a Google search on them, saw Paula's Choice 2% BHA recommended for them on a few sites. So, once again, I bought what I read about. Only this time, not only did those forehead bumps go away, but after ONE use, I no longer have any blackheads on my nose! I literally have thanked God for leading me to this product. I plan on trying the 4% to see if I notice any reduction in the size of the pores on my cheeks near my nose. But even if those remain visible, this product has made me so happy. I loved to read Paula's books with her reviews of beauty products for years, and now I love her product. Thank you, Paula!

My Holy Grail


As a teen I never struggled with acne however I would have the occasional cystic acne eruption on my chin. As I got older these became more frequent, generally coinciding with my menstral cycle. Around that time I found PC and started reading about AHAs and BHAs. I have sensitive skin so need to use AHAs sparingly. For a while I used a BHA made by another company that had good ratings on beautipedia. Unfortunately it was discontinued so I turned to PC to find another option. For a couple of years I used the lotion formula, but when PC reformulated and stopped offering the 2% lotion I switched to the liquid formulation. I was worried the liquid might be drying but it has never caused and issue. This has become a staple in my routine and I will not be without it. There are very few products I won't go without. These would be a moisturizing cleanser, a daily moisturizer with sunscreen and this liquid BHA treatment.

Smoother skin day 1


After applying on the very first night, I woke up the next morning to noticeably smoother, softer skin. I have very sensitive skin all year and very dry skin in the winter months but I have experienced no issues with this product. I can tolerate the RESIST 4% BHA just a couple of nights a week, it does give me smoother skin but really dries my skin out. I have not experienced that with this product. Great stuff!

I bought this to replace the exfoliant that I used to buy from Paula's Choice (it got discontinued). I used it twice so far on two separate nights, and have woken up with SUPER SOFT AND GLOWY skin. I love this product and I can already tell that it's going to become my go-to exfoliant! My nighttime skincare routine: - wash face with Clean & Clear's Night Relaxing Deep Cleaning Face Wash - use Paula's Choice Clear Regular Strength Daily Skin Clearing Treatment with 2.5% Benzoyl Peroxide - let dry a bit - follow with Paula's Choice Skin Perfecting 2% BHA Liquid - let dry a bit - then moisturize with Nivea's Original Daily Moisturizer Lotion *I only use skin clearing treatment + exfoliant once a day at night

I barely write reviews, but i have to write for this. I bought a travel size at first to make sure if it work for me. My skin is kind of sensitive. After 3 days, i can see a big change on my skin face. It might be a little dry but it's all good. I use this for day time, and booster serum at night. Highly recommend !

I have always had bad skin and like many others tried products and diets to cure my acne my whole life. I had been using AHA products for a few years which definitely helped my cystic acne but small bumps still covered my chin and forehead. I am so thankful I found this product. While there was an initial purging period I am glad I persisted because now my skin is better than it has ever been. I use this product morning and night it keep my cystic acne at bay and has totally cleared my pesky, smaller blemishes.

I have tried so many drugstore and high end skin care products over the years and nothing has come close to the immediate results of this product! It is so amazing and I will continue to purchase for years to come!

Review worthy


I usually never write reviews but this product has helped clear up my acne so much and has made my skin look brand new. I can even leave the house without any foundation and feel confident. I used to get horrible hormonal breakouts and this product has helped reduce them as well as the oiliness I used to get. It's a life saver!
