It works but spoils too fast


I found that this serum worked very well for me while it was fresh. My skin felt brighter and smoother, and it also helped with fading of some acne marks I have. I'd add a few drops to my lotion or apply directly. However as soon as the color in the bottle turned from pale honey to orange, this product started causing my skin to breakout. I currently have two half-full bottles that I can no longer use on my face. At this high cost, only being able to use half the bottle isn't worth it. I won't be buying it again. I do use a lot of PC products, and this is the only one that seems to go bad really fast.



I like this product


I have adult acne and my skin is sensitive. My skin is also dry and i have sunspots. It's a weird combo. Anyways my dermatologist recommended a vitamin C serum to lighten my sunspots. I tried this because of how much vitamin C is in it and the price is great. My sunspots have not disappeared but my entire face has definitely become more even and the lines on my face are less noticeable. The smell was a bit of an adjustment but I expect that with as much vitamin C that's in the bottle, which is a lot. It's a great product and great price. It has not affected my acne. Yes, I do use the Clear line by PC. It's the only product that has conquered my acne. Note, I do not use this serum every day because it makes my face very dry. I use it every other day to every 2 days. Enjoy!



I would have liked to give this a better rating but....


I have used the resist C15 Super Booster for quite a long time now. Basically because of what is supposed to do. I noticed some reviews stated that their skin turned orange-yellow. My skin was not what discolored. My pillowcase and sheets had large splotches of orange-yellow on them and really looked awful. It seemed like I was constantly washing them. Thinking the C15 Super Booster might be causing the problem I discontinued using it. Problem solved!!



Great booster!


I love this serum. I did see drastic results. I'm from Florida and went on a trip to New York and my skin freaked out and broke out badly. I don't get acne very often and if I do it doesn't leave marks behind but this time I was left with severe dark marks from the acne. I tried this serum and it lighten them and now they are barely there. My only problem with this serum is that I wish they would replace the packaging with a dark airtight pump instead to make it last longer. I'm thinking about getting another bottle and transferring it into an airtight bottle! Please PC change the packaging!

Great product, terrible packaging


I absolutely love this formula. I use it twice a day, and it has made my skin look and feel better. However, there is a serious downside to buying this product. The packaging is terrible for a Vitamin C solution, as the dropper and jar combination allows for the formula to be exposed to the air. My formula starts out transparent, as it should be. By the time I've used 1/3 of the product I start to notice discolouration, and then the formula slowly turns from transparent to yellow. This change in colour reflects that the vitamin C has oxidized, and that it's effects are now minimal. I don't know why PC would package this product in a jar/dropper combo. Their info page on vitamin C even states that any vitamin C product packaged in a jar should be avoided! I am annoyed that they don't even follow their recommendation, and that for the price I'm paying, this product will not be effective for almost 75% of its use. PC please rectify this!

Leaves yellow/orange discolorations on my hands and face! They can be removed with makeup remover, but still... definitely doesnt look good during the day! Really annoyed that this is happening!




i absolutely love this product! Have been using it for years


I have been using this product for several years & it's the best purchase for your $$$s. It's wonderfully light but still very effective. I am 64 and have been told many times that i have beautiful skin...thanks inpart, to Paula's Choice products-they are a staple in my skin care routine and have been for years. I have purchased higher end products for my skin care, but i always go back to my Paula's Choice products for their value and for their effectiveness. Why spend three times the amount for a Vitamin C Serum, i.e. Skin Ceuticals to name one, when for $49.00, The Vitamin C serum from Paula's Choice does an exceptional job and has similar ingredients? Thank you Paula's Choice for your research and for offering high end products without the high end prices.

An essential part of my routine


I use 3-4 drops of this AM and PM daily. I give it full credit for my even skin tone, which is saying a lot as it was once covered in post-acne marks and sun damage. I've used this product since it came out several years ago. I know others have reported an unpleasant smell or discoloration, but I have never had that experience. When I open a new bottle, it's always a light, almost colorless, odor-free liquid. It does yellow over time, but since I use it up within 3 months of opening, I don't see it change color too much. I used to only apply once a day, but I found that I wasn't using the product up before it expired. So, my only suggestion for PC is to perhaps sell it in two sizes. A smaller, lower price point version could help those who struggle to finish a bottle within 3 months of opening.




Okay product, horrible smell


Okay product, but the smell is killing me. Will not buy again. Rather stick to other boosters.




Turns my skin orange


I have been using this product as described. Once daily (in the evening), I would mix three drops in with my moisturizer and apply to my face after using my cleanser, toner and BHA. After several days I began to notice dark spots appearing on my hands, and when I would cleanse and use toner on my face, my cotton swabs would come off of my skin with a bright orange residue. Now that it has been a week, I have discolored, dark orange areas on my face, especially around my forehead and upper lip, that do not wash off. I am going to stop using the product immediately and hope the spots go away soon. If I do do continue using this product, I cannot foresee myself using it more than once or twice a week.
