Ratings & Reviews

I love this retinol!


This product was a huge help with the under eye wrinkles. Most retinol products you can't put under your eyes. This on is gentle, and potent enough to help.

Impressive results!


The results I get from thus products are the most noticeable of any product I have tried. It evens my skin tone and texture, reduces my pore size and minimizes fine lines. I tried the Clinical 1% Retinol Treatment a while back and it wasn't right for me. I have oily skin and it was too rich and felt heavy to me. This 1% Retinol Booster is much better. It has a thinner, lighter texture that is better for my skin type. I have been using this for almost a month now, 3 or 4 times a week and have not had any irritation or reactions. The results this product delivers are great and I noticed them after the first use. Well done, PC!




Holy Grail Retinol Product (and I've tried a lot)


I have done a lot of research on retinol and experimented with a lot of products, and this is my go-to retinol product. I'm shocked to see reviews that comment on it being harsh, as I've never had any irritation or negative reaction to this product at all, even from the first use (which is why I love it!). I do get a bit of peeling with the PC 1% Clinical Retinol, which is why I've settled on this one. I only trust PC for my otc retinol because they take the research seriously and package it with incredible care. If you're using a retinol product that is in a clear container exposed to light, you should probably shop elsewhere. Same goes for exposure to air. I totally trust the PC packaging 100%. I know this product can be used on its own, but I love that I can add it to my other serums. Because it is a light texture, I add it with my first layer of light watery serums, before I add the second layer of thicker serums (1x/day, before bed). I mix them together in the palm of my hand and than apply to my face. Any leftover goes on my neck, decolletage, and backs of my hands. Since beginning use 6+ months ago, my skin is brighter and more even-toned. Fine lines have reduced. I'm so excited to see what else it will do in the upcoming months/years, because I plan to continue using it as long as it is available! I don't think this is available in sample size, and it can be tough to to jump on an expensive product without having an option for samples, but I'm on the website tonight purchasing my third bottle (and I'm buying two tonight) - so it it might be worth it to take the chance! Save your box and insert in case you decide to return it for your $$ back, but I guarantee you won't!!

Not for every day if you have sensitive skin.


I'm 28 and this is the first retinol product I've ever used on my face (not including eye creams). If you have super sensitive skin this isn't great to use every day unless you want a one way ticket to dermatitis city, but alternating this with the 10% Niacinamide has made a huge difference in my fine lines and skin texture. I only add one drop to my CosRX Snail Mucin serum at night and that seems to be plenty. Will definitely repurchase this now that I've learned how to use it appropriately!

So thrilled with this!!!


I'm in my early fifties and have highly sensitive combination skin. I constantly try to balance my skin issues: dryness, irritation, rosacea redness, random hormonal breakouts, and those little hard white bumps with the funky medical name. It's a perpetual see-saw. (I give my background because if you're like me, I look for reviews from someone who has similar skin.) I actually bought two products together: Omega+ Complex Serum and Resist 1% Retinol Booster. (I'm putting this review under both products.) After cleansing and toning, I mixed together one pump of each and put it on my face and neck. It went on my face like silk; smooth and soft with absolutely no pulling at my skin at all. And I'm happy to say that I've had no issues since I started using this about two weeks ago. No breakouts, no burning, no reactive redness! I've even had compliments on my "glowing" skin! My face is smooth and soft, and the redness is calm. I'm so excited about these two products and am tossing all the other retinols that I've tried. And on that note, all other retinols have been too harsh for my skin. Paula, I didn't know this was your gentlest retinol until I saw it in a response to a review (or video) somewhere on your site. I wish I had known earlier. I'd have gone straight to this instead of trying a few of the other ones.

Game Changer


This product was an absolute game changer for me. Once I started using this, after a week I noticed a huge difference in my skin. My breakouts were healing faster and my skin tone was absolutely brighter. It's so lightweight and doesn't clog my pores. I think it is even helping my blackheads to be reduced!




Really works!


This booster does more for my skin than any retinol product I have ever tried. Best part... no peeling!

Depend on this for clear, healthy-looking skin.


I have used this product since PC debuted it a couple of years ago. I like it better than PC's Clinical 1% Retinol product, which has a heavier texture than this 1% Booster. My skin is truly combination/oily, and I've learned after trying both retinol products that the Booster's lighter texture works best for me. Even though both products contain 1% retinol, I found that the Clinical product would sometimes cause a reddened, burn-like appearance and painful sensitivity on my face--accompanied by eventual peeling--and I would have to stop using that product for several days up to a week in order for my skin to calm down. But with the 1% Booster, I've never experienced that level of skin irritation; I've only seen consistently good results in terms of keeping my skin clear and youthful-looking, with no irritation whatsoever. I usually apply the Booster directly to my face, without mixing it into any other products. Overall, it is a must-have product for me and I will continue using it for as long as it's available.




Love it! And figured out how to dispense just a drop.


I love this stuff-- I have sensitive skin and rosacea. By using Paula's Choice products and avoiding certain trigger foods I've gotten both under control and my skin is looking great! This is the only retinol product I'm able to use. I love that I can customize the strength and that I can add it to a moisturizer that my skin likes. I tend to use this every other night, or every two nights, depending on how my skin feels. I also figured out how to dispense just a drop-- you lightly push the pump down, about half of a centimeter and a small drop is dispensed. If you push down harder and push the pump all the way a larger amount comes out. Getting the retinol to come out in a drop has been a great way to get a consistent amount of product, which makes it easier to mix into my Resist moisturizer. Before I was just wasting the excess product and I'd still end up using too much and irritating my skin. The product doesn't feel sticky or filmy. There's a really, really, light, faint scent that I don't notice after I apply. (For what it's worth, I do not like scented facial products.)

Really works


I was a bit apprehensive about using Retinol on my skin as it is very sensitive. I used it a few times a week and then gradually increased to every night. I have had no averse reactions and I love the way my skin feels in the morning. The formula is a little greasy so I have to wait a while before I apply my moisturizer over it but the results have been well worth the extra few minutes it adds to my nighttime skincare routine. I'd definitely repurchase this product.
