Brightening and Clarifying

Comments about Resist C15 Super Booster - 0.67 oz:
I use this product morning and night in a "home-made" serum using this product, the new PC Niacinamide Booster and tea tree oil. I suffer from severe adult cystic/inflamed acne, so I get very excited when I find a rare gem that not only doesn't break me out, but actually improves the state of my skin. This product (along with prescription tretinoin and PC salicylic products) has given my skin more brightness and clarity than I've seen in a very long time. Redness from post-inflammation hyper pigmentation (acne scars) has reduced significantly, and overall my skin just appears much healthier and radiant. Great product, well worth the splurge.
Bottom Line Yes, I would recommend this to a friend

Youthful glow is back
By Emilie L

About Me Beauty Conscious
I have dry, VERY sensitive skin, so I was skeptical that it would help the dull dryness that has developed over the last year. I was pleasantly surprised to find that this product softened my skin and brought back the glow I once had as a teen and in my early twenties. HOWEVER: I found that 2-3 drops was too much for my skin - it made it too oily. I now use one drop with my moisturizer at night and wake up with very clear, fresh skin. It lost a star because it took a while to figure out the right amount, and because it should really stay in the fridge (inconvenient). But, I will continue to purchase over and over. Thank you!

About Me Minimalist
What I really liked about this product was that it only took a week to start showing results. It has really brightened up my skin. My nose usually takes a lot of sun damage and has a lot of brown spots, it seems to be lighting up, but I've only used it for two weeks now. It doesn't have a pleasant smell, will definitely recommend despite it.
from West Hollywood, CA
I got a free sample size of this product in my latest Paula's Choice shipment. I disregarded it for a while because I wasn't sure what to do with it, and on a whim started using it this week. It's been a full week and my skin tone is noticeably more balanced and even seems less oily. I apply two drops to my PC4Men nighttime moisturizer along with some benzoyl peroxide for acne. In the morning, my face always feels very calm and glowy. Some have commented that the smell is bad, but I haven't noticed that. To me, it smells a little like cinnamon. I apply this on my face and neck and haven't noticed any irritation. I'm not sure I'll buy the full size one due to the price, but the product does do exactly what it says. It's pretty cool.

On my 3rd bottle and very happy
from Redwood City, CA
I use this product after exfoliating on my face, neck and decolletage. It works the first time you use it which is amazing. Really brightens the skin and reduces redness. I followed someone's advice which was to purchase the small sized vial and refill that each week, and store the large bottle in the refrigerator. It is a great tip and keeps the product fresh and effective.
Works for me
By Nancy DE
from Portland, OR
I keep this in the fridge, and add two or three drops to the antioxidant serum or my moisturizer. I use it twice per day. I've been using it for a month so I'm not sure how long before the product oxidizes. I've been really happy so far. I've noticed softer and more young-looking skin, and definitely a more even skin tone with less redness. Time will tell if it helps with aging and wrinkles. To me, it smells like salmon jerky, but I don't particularly mind. I've particularly noticed that if I use it at night, I wake up looking much fresher than if I don't.
I love this!
I love this product. First of all the packaging is absolutely amazing. I feel like a little chemist mixing this with my Moisturizer everyday the only thing that would making it better is if it came with a mixing plate or something. Anyone looking to add vitamin c to their regime I'd suggest this. Perfect and easy
I bought this even with the comments on the smell, since I really wanted something to help with the hyper-pigmentation left behind by my blemishes. First off, this stuff smells like bacon. Don't ask me how, it just does. So as bad as the smell is, and it lingers for a while, I would have tolerated it, if it had been effective. But it has not improved my skin or blemishes. Since I have started using it, I have also broken out more than a few times. I finally cut this out of my skin care, and my break outs stopped... I used it at night. Would have loved if this had worked. I love and have a lot of PC products in my day/night routine, but this will not be one of them anymore...
Bottom Line No, I would not recommend this to a friend

My favorite PC product
Love, LOVE this product! I have tried most (if not all) of PC's serums) and this is my absolute favorite. l start to panic if I think I'm running low. I tend not to mix or layer products as I never seem to have much luck with that, either they pill up or I break out. So I use this alone on days that I know I won't be going anywhere. I just slather it on and wait for the magic to happen! Softens my skin and gives me a beautiful glow! I even used it, like PC suggested, on a difficult callus/crack on my heel that wasn't responding to kerasal, which has Salic acid. I was hesitant at first to use it that way since it's a little pricey, but I thought what the heck, I'll give it a try. I was amazed, it was visibly improved after I put one drop on it. Another drop the next day and it's now gone! After months of using kerasal, heel rescue and a pumice stone, 2 drops of C15 is all it took. Crazy. The only downside, and it's a minor one, is that it can be a little tacky once it dries. But that may be because I tend to use a lot of it. Either way it's not a deal breaker for me since it works so well. Others may not have that issue if they mix it with another product. I encourage people to give this product a try, I can't say enough good things about it.
Oxidized very fast
I was very exited about this product and the first month I was ok satisfied. I felt that the product was a little sticky but after mixing it with my serum the consistency was better and did not leave a film on my face. The smell is not that great but I don't care if something works! However after 1 month of opening the c booster the content turned yellow and oxidized very fast. I was hoping it would last the 3 months that it says on the package without turning that yellow and no improvement at all. I use only Paula's products and usually love them, This is the only time I have been disappointed over the results.
