Oxidizes too quickly, poor value.
from Bay Area, CA
About Me Beauty Expert
Comments about RESIST C15 Super Booster - 0.67 oz:
I used this for a couple of years, and did find it helpful in evening and brightening skin tone. However, I've given it up - it actually is a poor value because it oxidizes (turns dark amber) so quickly after opening the bottle. I even keep a small amount in a sample bottle for daily use, refilling from the full size bottle (which is stored in a dark closet) - but it still doesn't slow down the oxidation. If there was another way to package or formulate this product so it wouldn't oxidize (and thus waste) so quickly, I'll be first in line to buy. Otherwise, I'm going to pass from now on.
Bottom Line No, I would not recommend this to a friend

Smell? Who cares, it works!
By Sheena Bo Beana
from Estes Park, CO
About Me Minimalist
This stuff smells a bit like hot dogs, but it airs out quickly...I don't care because it works!I've been using Paula's Choice products for over a year. My skin has gone from acne prone and oily to clear and normal. After my active breakouts were cleared, I was left with hyper-pigmentation on my chin from my most persistent breakouts. I started using the C15 mixed into my PC serum, and I have ZERO red-marks on my chin. They have all lightened, and now I'm comfortable going out makeup-free (well, with just my tinted PC Resist Wrinkle Defense SPF 30 which provides light coverage).I, like many other reviewers, bought the sample size container for daily use, and I refill it with the regular-sized bottle stored in my refrigerator. My first regular-sized bottle (opened 2x per day) lasted 2 months; however, my second bottle, stored in the refrigerator and opened every other week, is still crystal clear after over 4 months.
Bottom Line Yes, I would recommend this to a friend

After several years I gave up
By Running from wrinkles
from Home of the Oregon Ducks
I used this product for several years but I have given up. I used it daily mixing 4 drops into my serum in the morning. I found that if you don't mix it into a serum, it is so runny that it's hard to apply and it runs out of your hand before you can get it on your face. I do think it works and love what it does for my skin. It's an amazing product which is why I hung in there so long. The issue I have is how it changes color so quickly. It darkens to become an orange amber after opening. I have fair skin and you can see the oxidized vitamin c on my face. It tints me orange like I am wearing a cheap self tanner. I have switched to the 25 percent "spot" vitamin c also mixing a pea size amount in ,y serum. It's much more expensive and it doesn't work any better that I can see. But because it's in a tube and has a base silicone or cream, it doesn't oxidize. This great liquid would be great in the pen style dispenser that Paula has for the firming liquid. Paula knows this product oxidizes and changes color but continues to package and sell it in a container that allows air in. I would like to see that addressed. I'm actually thinking of changing brands for the first time on this product because the 25% is so expensive and this product would be fine if it was packaged better.

Great Product, Just a Couple "Glitches"
from Marana, AZ
About Me Beauty Conscious
This is a really good Vitimin C product and a great value compared to very similar product from another brand that I used to use.My two negatives:1. Using the amount directed on the bottle, I cannot seem to get through the bottle before it oxidizes (diminishing some of its value for me). Reading other reviews I will now store in the fridge to see if that keeps the product stable longer. Also will try and use twice a day instead of just at night.2. When using at night it causes orange "stains" on my pillowcase. I did not see other reviewers mention this. I sleep on a satin pillow case and the orange marks do come out in the laundry.So, if you can get through the product before it oxidizes in order to get the most benefit from it, I recommend it!

from Orlando, FL
Love the product; it does exactly what it claims too. I have a lot of small bumps around the sides of my nose and this clears them up/smooths them out over night. I just wish it came in a smaller size bottle. Even using this every day, I can never finish the bottle within the 3 month time frame. I hate throwing my money in the trash. :(

I am 100% a dedicated Paula's Choice customer and I can not say enough good things about the brand. However- This serum smells so horrible. After I apply it, the rancid scent stays on my skin the entire day. It is an almost unbearable smell to me and it's making think that this serum has either expired or gone bad and I just opened it a week ago. The scent smells like dirt and hot dogs that have been left out in the sun all day. I think I will have to discontinue use of this product.

My Skin Hated This
from Roanoke, VA
This product is expensive and it irritated my skin beyond reason. Don't waste your money.
Brighter skin after first use
My dull, aging skin looked immediately brighter after just a single use of this booster. I'm planning to order it in full size... and look for other products to help with moisture loss, cell regeneration and protection. A gentle reminder that it's time to update my skin care regimen.

Only C Serum I Can Use
By Kim in CA
I tried other C serums that left my skin irritated. This one is perfect and has never once left my skin red or itchy. I use it twice a day--in the morning I mis it with my Skin Balancing Super Antioxidant Serum, and in the evening I mix it with my Retin-A cream. Changes do not happen overnight, but they do happen. My skin is more even and looks brighter and younger. I used to be a product junkie but I have been a loyal Paula's Choice customer for years, and my young-looking skin shows for it!
Hands Down the Best PC Product
This product is by far my favourite PC product. I did not find that the results were evident instantaneously but consistent use twice a day, mixed in with an antioxidant serum, or patted on the face alone has proven to give beautiful results. For me it has been the most effective for over all skin texture, brightness and improvement in pigmentation. I have a more youthful appearance and definite glow since I introduced this product consistently. My skin does not tolerate daily exfoliating and responds better to weekly 10% AHA and occasional 5%, also I can only use RetinA once weekly, the results of which are great but the biggest impact and most tolerated product has definitely been the C-15 booster. I highly recommend this product and suggest that if you don't notice improvements immediately, stick with it and before long you will reap the benefits.
