I have used Paul as choice for over 10 years .thank you paula!!!

Another great booster!


I was already in love with the oil renewal booster but decided to try this one to brighten and even my skin tone. Now I love this one too! I combine it with the oil renewal and my skin looks amazing. Please don't ever discontinue these boosters! I only wish they had bigger sizes.

Love C15


I really love this product. I have combo, oily t-zone, acne prone skin & this has not caused breakouts. I've never had a bottle oxidize & I do not refrigerate it. I usually get 4-5 months of use before I run out. I have used PC products for many years. My skin has improved greatly. I'm 55 & the only lines I have are a few tiny ones under my lashes & were there at 45. Thank PC for the wonderful products for all skin types & concerns. Also a big thanks for the prices staying reasonable & affordable, unlike quality products by other brands.






Love this booster, has brightened up my dull skin like no other. Great to add to other products, have bought several times and believe it works great, even for combo skin!!




Must have


Skin brighter, firmer skin, smoother, after using serum around eyes. Noticed less darkness and puffiness. Fyi used in conjunction with other PC products however this is no one on list with sunscreen fyi smell, no fragrance.




I don't know why I waited so long to try this!


I got this on a blog recommendation (goals to get glowing) because I wanted to find another Vitamin C that wasn't as expensive as my SkinCeuticals favorite....I think I like this one better! It FEELS good when you put it on (not just like putting water on). Absorbs well and I think my spots are slowly starting to fade...plus, I have an overall glow (That's not greasy!). This combined with my old tried and true PC Resist Antioxidant / BHA 2%, - winning combo to combat my ol' lady face!

Definitely recommend


Purchased it for the first time in February, 2018, it lasted exactly 3 months. I kept it in the refrigerator and it did not oxidize at all, 5 star review based on price and effectiveness of the product.

I love this stuff


I have a normal/slightly oily skin type, with hormonal acne. Skin care products often break me out, and so I have to be very careful about what I use. My skin care routine ends up being extremely minimal. Right now, it is the C15 serum followed by sunscreen in the morning, and then the PC 2% BHA followed by moisturizer at night. The BHA does wonders for keeping breakouts to a minimum. But the C15 booster is such a great addition. It is essentially a water-like texture. It is light weight, and absorbs very fast. It does not break me out, the way thicker textured vitamin C products have in the past. Instead, I notice even clearer skin. I have noticed less breakouts and a more even, brighter skin tone overall from this product alone. I love it for preventative, anti-aging purposes and also to reduce both acne breakouts and uneven skin tone. Also-- I do use this around the eye (avoiding the eyelid) and have zero irritation. Sometimes skin care products do sting my eye area, but this does not. For me, the C15 booster does what it is claimed to do, and is a really fair price as well.

Favorite product, needs smaller packaging


This is hands-down my favorite PC product. It is the one miracle product that gives me 1-day results by getting rid of any red marks or discolorations left over from pimples and such, and it seems to work even better on days when I'm out in the sun. However, I've only been able to buy this twice because of the hefty price tag, and only the travel/sample size, because after reading over everyone's reviews, the full-size doesn't even last for three months before oxidizing. For that reason, I've been waiting for 2 years for them to change the packaging and still nothing. I'm no packaging expert but I wonder, even after hearing everyone's comments, if they insist on selling it at this size, would it work better if they sold it as a set of 2-3 small bottles? That way you'd be getting the same ratio of product-to-money spent, with the bonus that the whole batch won't spoil in one go. I hope they bring the travel/sample size back soon because I love to use this in the summer!




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!
