Why is it different?
C15 Super Booster contains a highly concentrated form of vitamin C and an assortment of skin-stabilizing antioxidants and skin-replenishing ingredients. Combined, they provide exceptional results including improving the appearance of uneven skin tone, brightening a dull complexion, and helping skin ward off the impact of environmental assaults.
What does it do?

Diminishes visible signs of aging for smoother, brighter, and firmer-feeling skin with a blend of 15% stabilized vitamin C (l-ascorbic acid) at a pH of 3.0, potent antioxidants including vitamin E and ferulic acid, and skin-smoothing peptides. You'll see dramatically younger-looking and more radiant skin day after day!

How to use

Dispense 2-3 drops into the palm of your hand and then apply to your face. Add a couple more drops if you will also be applying to your neck and chest. During the day, finish with a moisturizer with SPF 30 or greater. Can be applied under the eye area, avoiding the eye itself.

Ratings & Reviews

This product changed everything!


I've been struggling with fine lines and dryness. I started using this before my serum and my skin is glowing and dewy. This is one of the best products by PC. I'll definitely be buying again.

Lots of Repurchases


I've lost count of how many bottles I've used. I set a reminder to throw it away at 6 months, but it's always gone by then. I tend to use it every morning, as my first step, even if all I do is finish with sunscreen. Sometimes I add other products, but it's a constant. I started using it at 28 and will be 31 in 3 months. I first picked it up with the hopes of evening out my skintone because some untreated acne from 24-25 didn't look great. My mom was so impressed with my whole skincare routine. She said that she thought that I was going to be scared forever. Now I can skip foundation! I tried another brand one time and didn't even use half the bottle before I went back to this. It feels better, lasts a long time/doesn't require refrigeration and I know that it's effective. This was the second PC product that I ever tried. And one that I would hate to give up.

This serum booster is amazing. It has brighten my face like no other product has ever done. I use 6-7 of Paula's choice products and they ALL have made my complexion glow and I've seen lines not do defined. Also for the way these products actually work the prices are great..not cheap but not super expensive..plus they actually work.. I've found my holy Grail from Paula's choice!!



Life changing


One of the top skincare products I've ever used, saw a difference immediately, I use it everyday with the niamacide booster and the combination is incredible, even flawless skin tone, glowing healthy face I'm Obsessed thank u Paula's choice!






I combine this with pc retinol serum.This is the most effective combo I have used so far. I can't believe it's only been a little over a week my skin is bright and soft looking.I always apply sunscreen rain or shine. I'm 51 and get called miss almost everyday lol. 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!
