Ratings & Reviews

Wonderful produce


I have EXTREMELY sensitive skin & wondered how I'd go with this product. The first time I used it on my face & the backs of my hands (no lips or eye area) my skin tingled slightly for about 30 seconds so I suspected I would break out in a rash or that my forehead would peel off. It also felt a bit "grainy", like a lightscrub, but I didn't rinse it off, I left it to see what would happen. Nothing negative happened. I used it again the next night, but I used less & the same thing, but the tingling was not so pronounced. After I'd used it every night for a week (with very vague tingling) on my hands & my face, my skin was noticeably softer, smoother & my "blotches" were less visible. This was particulary noticeable on my cheeks & the backs of my hands. I also love how it makes my skin feel. I now wear it every day as part of my morning routine (with sunblock of course!) instead of at night time. My nightly routine uses another great product from the Boost range. Anyway, the C25 is a great product in my opinion. Pricey, but what price a youthful look, without surgery?

Try anything once!



Just amazing!!!


This is my first review of Paula's products and I'm not quite sure why I haven't reviewed before because I absolutely love the products! I got the C25 for my fairly large pigmentation spots under my eyes. I have been using this as a spot treatment for about 3 weeks twice a day and my spots are almost gone. Absolutely freakin love it!




Fades freckles/brown spots


I ordered the travel size of this because of the price and average reviews but I'll definitely be ordering the full size when I run out. I bought it to fade freckles/dark spots and have been patch testing it for around a month on a few stubborn areas -- these are spots that would peak through even a ton of concealer and they've now faded to a manageable level. I have sensitive skin, so I just dab a tiny bit on the spots every second day and it hasn't caused any irritation.




Love this cream


I noticed a huge improvement the next morning. I'm very impressed with this cream and will definitely repurchase. This will definitely be a regular daily addition to my skincare.

This product delivers on its promise. It will break up dark spots of HYPERPIGMENTATION from past blemishes, sun spots, melasma. 3 SUGGESTIONS BELOW: Use everyday, every other week, under sunscreen. See the difference in 1 month. Use it as a spot treatment. Apply toner with fingers, then take 1/2 pea size of this and dot it on problem areas, use slip from toner to spread it around entire face! Can you say "BRIGHTENER"?! Be creative, create your own way of using this wonderfully formulated product!

Healed Picked Acne Overnight!


No, you shouldn't pick at acne. Of course you shouldn't. No one should. But everyone does at some point, and if you're anything like me, you regret it immediately. I was using this for age spots (which it has worked well for, as long as I keep using my sunscreen daily), and accidentally put some on a picked spot. Woke up in the morning and the skin was HEALED. Still a little red and tender, but holy cow! HEALED. Fresh baby skin. I was amazed and thrilled. I'm not saying go crazy picking at your face, but I have begun using this along with PC's wonderful BHA products on any acne that pops up. And it helps the redness and helps heal it quickly. This is now a must have in my skincare routine. I'll take healing acne over diminishing age spots or wrinkles any day. So the fact that it also helps with age spots (can't say yet if it helps with wrinkles) is a huge plus. The only downside is cost. It's expensive! But it works!




works on acne...who knew?


I'm 47 with dry skin that still breaks out occasionally (nose/t-zone) area. I've used the full suite of Paula products for about 10 years and while I occasionally dabble in another line, I'm loyal to the results I've experienced. I received a sample tube of this and tried it out on a couple of little acne scars. No change to the scar tissue itself but over several weeks redness faded. I used a little on a pimple that popped up on my nose overnight and was suprised that it flattened and then disappeared the same day. Since then I've used this as a go to product on little breakouts and it is very effective.

Magical. Like a gift from my Fairy Godmother


I've had frustrating, oily, blemish-prone skin since my early teens and nothing has ever fixed it. Doctors, Dermatologists, $100 a bottle exfoliants, etc., until I ordered a full routine's worth of products from Paula's Choice, I've never felt that I didn't have terrible skin. After two months my skin tone is much more even, I'm not having breakouts, my face doesn't feel gross and oily AND the damaged collagen on my nose (that "dent" in your skin that lingers after a pimple is gone, which drove me INSANE) is barely visible. From the reading I've done, I think the Vitamin C treatment had a lot to do with that, but more than anything I just want to suggest doing your whole routine with Paula's Choice. I use the Oil-Reducing Cleanser, 2% BHA Exfoliant, this treatment and Invisible Finish Moisture Gel. I'm about to order more of this, some toner and something with SPF. Thanks PC, you're the best!!

worked for me!


I really liked this product, not sure why everyone says it dries pasty or whatever. You dab it on but make sure its absorbed into the skin. Dont leave excess on your skin. I had a few acne scars on my face, and after applying it twice daily on my skin for 2 weeks I noticed it visibly lightened. After 2-3 months, it disappeared. I later combined this with bha 9 and vitamin c boost but honestly this is the product that i used daily. Also, make sure if you apply it during the day to use sunscreen with a strong spf as vitamin c will make your skin more sensitive to the sun. No sunscreen means your skin may get worse. I honestly love this product and cant rave enough about it to friends and family. My aunt who noticed my improved skin has even remarked on it and now is ordering one too.




Great product!


Works beautifully on my rosacea. I don't want to be without this amazing product. It has been a miracle for me.
