How to use
Apply once or twice daily after cleansing, toning and exfoliating. Dispense 2–3 drops and add to your favourite moisturiser or serum. May also be used alone. For daytime, follow with a broad-spectrum sunscreen rated SPF 30 or greater. May be applied around the under-eye area.
Thank you for submitting your review! It will be reviewed by our staff before it is posted.Unfortunately this product turns my face yellow. It seems to be clear or very pale yellow in the bottle, but once applied to the face turns yellow and darkens to more of an orange across the day. I only use 2-3 drops. I don't know if that means it's oxidising very quickly on my skin and perhaps even turning into a pro-oxidant? I use sunscreen and other antioxidants during the day, but that doesn't help. Used overnight, I also wake up yellow. My partner was concerned I had suddenly developed jaundice, but I said it's this new serum. Very disappointing. I also didn't experience any brightening effect, whereas I get instantly brighter skin with The Ordinary Ascorbyl Glucoside 12%, which is a significantly cheaper product (and no turning yellow/orange!). However, stable derivatives of vitamin c aren't supposed to be as effective for anti-ageing as pure ascorbic acid, so I was looking to upgrade. It's a shame this product didn't work out. It's very expensive too. Too expensive in my opinion, even during a promotional period. I also seemed to break out in the first day or so, which never usually happens. On the plus side, I didn't experience any stinging or irritation. No benefit either, but I only used it for a few days and couldn't continue due to looking like an oompa loompa!
Customer care: Hello, and thank you for sharing your experience with us - we're sorry to hear this didn't work as expected for you. This is not a common reaction but we understand every skin is different. We are glad that you contacted us to organise a return.I bought this serum in sep-2020, used it for a week. It broke me out quite badly. I stopped using it. Unfortunately I wasn’t aware about money back guarantee. Quite disappointed 😞 as I am a huge fan of other products of Paula’s choice.

Please contact a member of our Customer Care team, who can assist you with a possible alternative.I really wanted to love this product after reading so many positive reviews. I did end up using the whole bottle (as I paid a lot of money for it) and had the intention of repurchasing, but for me this product made my skin break out almost all the time. I even stopped using non-PC products and still my skin was not having a good reaction. So I can say it was not a combination of using other products. I gave it three stars because I did notice a slight difference in my skin, but not enough to be amazed. Also be careful if you don't mix this with a light moisturiser as it will stain your palms and fingers.Had very high hopes for this product, but after trying it for 2 and a half months, I’ve seen no change to the radiance and clarity of my skin. I still have the same blemishes and spots, the only thing the product has helped with is speeding up the clearance of scars - so 3 stars for that.

And I love the fact that it helps me with fighting against sun damages as well. Its texture is perfect.I’m obsessed with the C15 Super Booster, I’ve always been a little scared to try vitamin c’s after never finding the right one for my skin.. I have combination/sensitive skin and often find a lot of actives and skincare products can irritate. This is seriously worth buying if you’re looking to implement vitamin c into your routine!Love this! It’s the best Vitamin C serum I’ve used and the results are instantaneous. Whenever I use this and see my face in the day I’m always so pleased at how glowy it makes my skin. I’ll never stop buying this now. A definite winner for me.This is definitely the best vitamin c I’ve tried. I have acne prone skin and I particularly struggle with cystic acne with red marks that last up (and beyond!) a year. I’ve used a 3 month supply of this and I’ve only had 1 bad spot that will have probably linger and scar. I’m currently pregnant and I was worried that my skin would worsen like my previous pregnancy, but so far so good (combined with other acne-fighting products). Aside from that, my skin feels really smooth and soft and I think that possibly some of my acne scarring looks a bit better.
I use this once a day and a using a liberal amount lasted exactly 3 months. The dropper is a bit annoying but I dispense into my palm and then use my other hand to rub over my face and neck.
I’ve already repurchased 2 bottles when there was an offer, and I imagine I’ll continue to do so :)I've recently learned of the benefits of Vitamin C as a serum and after trying a few, some more expensive than this, this is hands down my favourite product. My skin has never looked for glowy, fresh, dewy and bright (even after sleepless nights with a newborn). I hope this is never discontinued and I recommend it to everyone. Thanks PCWithin the last couple years, I've discovered the benefits of vitamin C in skin care products and I've tried most of them. Paula's Choice formulation is the best on the market. No irritation, beautiful results, hydration without heaviness and long-term benefit. I'm not particularly fond of the packaging (dropper dispensing) of this product but given the formula, it's probably unavoidable. It really must be used within three months once opened and it's important keeping that in mind. Also, avoid letting the product get warm. That's not a criticism of the product, it's just the nature of vitamin C in skin care products. It loses effectiveness if it's subjected to heat or not used within a few months.This product is great at evening out the skin tone and fading acne marks after consistent use (3-4 months). My complexion is glowing after applying this product. I have oily/combination skin though, and sometimes I do find this product making my skin shinier than usual which isn't great but this is outweighed by the skin benefiting ingredients this serum contains so can't complain :)I’ve been a Paulas choice covert for about 6 months now and have purchased many of the core range with great results. As with exercise at the gym, I think you can plateau with skin care and while I am happy to maintain, it’s been great to see the changes so quickly during 6 months....having been extra tic with my initial results I thought that it would now be a slower ride..... not after having purchased this! I saw a whole new set of results! Skin tone improved more, dark spots faded, crows feet diminished further! Bloody brilliant!The first vitamin C serum I have ever tried and what can I say!! I can’t start my morning without it, it’s made my skin glow and it definitely had lightened my brown spots. I have just purchased a second bottle! Thank you PC :-)The C15 Super Booster is gentle and makes my skin look and feel smooth and comfortable. Having run out of it, I was reminded how much I rely on this product now I've got it again. I'm in my early fifties and have can't tolerate fragranced or volatile products. I never need worry about using this - I've never had an unfavourable reaction using it. Other companies have good vitamin C products but Paula's Choice is the best, in my opinion.I tried many Vitamin C serums out there and never found one that actually made a difference until now. I never write reviews but I felt like this one deserved it. I use a 2-3 drops all over the face after hyaluronic serum and before moisturiser - Looked more glowy after first use and noticed any hyperpigmentation from old spots fade with consistent use. While I am only in my late 20s I notices mild crows feet appearing under my eyes but after using my Paula's Choice routine for a few months they completely disappeared, which I was not expecting. I also use their Retinol serum, AHA BHA exfoliator and super antioxidant serum in circulation with the Vitamin C and I feel like this combination has completely changed my skincare game - no breakouts just bouncy, glowy skin.Genuinely the best thing I’ve used on my face. In just a few days my skin tone is evened, red patches gone. Haven’t had skin this healthy looking for years. Happy customer!Since I started using this, people have actually commented how healthy my skin looks! Devastated it’s not been available for a while as i’ve nearly run out of my 2nd bottle! Expensive but definitely worth it!!I love this, I’m 21, black & have very bad hyperpigmentation. I use this during my PM routine, i alternate between using it on its own or mixing with my moisturiser and its only been a few weeks but certain scars are looking lighter already. I’m always going to repurchase thisI literally can not get enough of this product. It has made my pigmentation less visible and has evened out my skin tone. My skin is now glowing and I wear a lot less makeup. Wish I had discovered this product 20 years ago!This product like a magic. Brighten up your skin. My skin looks better even after the first time. I defo recommend this product .I had a false start with this product - the bottle I first received was off, but the Customer Service team - who is amazing - fixed this immediately with a replacement bottle. However, I'm still not enamoured with this product, after using the replacement. Despite keeping this in the dark AND in the fridge, it quickly went off. It does say on the product page that it has a three month shelf life but my bottle didn't make it that far. During the period when I was able to use it, I couldn't get on with the watery texture. Mixing it with a cream (as suggested) resulted in the C15 running down the grooves of my palm and disappearing down the sides of my hand. My palms got more product than my face ever did! If this had a slightly thicker, more serum-like consistency it would be easier to work with. The pluses to this product was it didn't sting and the Vitamin C/ferulic acid/vitamin E combination is excellent. Just not the consistency. Sorry, PC, I won't be ordering this again.
Customer Care: Hello, and thanks for your comments! We are always looking for ways to improve our products, so we will pass along your feedback to our Product Development team!I have always been plagued with acne, large pores and an uneven blotchy skin tone. I decided to try this as I have a number of other PC products which I swear by. Best decision I ever made! My skin now looks smother and brighter and all the blotchiness has disappeared. I just add a few drops each morning to my moisturiser under my make up.I've always been blighted by uneven skin tone (which looks worse after a bit of a tan in summer) and skin pigmentation. I've used this for 3 months now and it's made such a huge difference to the brightness and clarity of my skin, my ever eagle-eyed mum thinks my skin has never been better! Uneven skin tone has evened out slightly so hoping that using it a bit longer will help sort it out a bit more. Took awhile to work out a routine that worked for me but ended up using it in the morning after my serum, it's a little bit sticky so needs some time to sink in.I love this, I use it in the morning with my retinol booster, and I can see a huge difference since I started. My skin looks more even and fresh, it's amazing. Dark spots (old sun damage) are fading. I just wish it wasnt as expensive because I am not sure I can keep using it, hence the 4 starsLove, love this product! I use it every morning, two or three drops in my serum before following with moisturiser and then SPF. After two weeks my skin is more even toned, scars appear faded and even sun spots have faded. Love it!!There's not much to say, this thing works. It brightens my skin, helps to fade red marks from my occasional spots. I'm not sure if it smooths my skin but it certainly helped decelerate the production of any new fine lines as I haven't seen any for a while. It doesn't, however, reduce brown spots that's not caused by breakouts (or maybe it does but very very slowly) so don't expect liver spots or general uneveness to disappear like miracle with this treatment. I also find it to work very well to start with, then it eventually just doesn't work as well anymore - maybe it's to do with the oxidation of the product.I really like this product , is very good at helping fade red marks from post breakouts and overall brightens the skin. I’m very pleased now you can get it in the UK because before it was a struggle to get it from the US . Highly recommend this product if you are looking for something to brighten your skin and help fading brown/red marks.So thrilled that this product is now available in the UK. I have recently moved here from Australia and have included this booster in my morning routine for years now. Absolutely love it! It does what it says. I am 54 and my skin looks and feels great. It brightens and evens skin tone keeping brown spots at bay despite spending all my teens and twenties ‘sun baking’ and with minimal if any protection in the Australian sun. Another brilliant product from Paula!I love this product and have been using it since before moving to the UK. Now that it's here I'm excited to finally get my hands on it again! It's great for scars and marks, evening out skin tones, and generally brightening skin. Don't use too much that it gets sticky, a little goes a long way for this product!I have been using PC products for a number of years & gradually, after some experimentation, I have built a fragrance and animal testing-free routine perfect for my sensitive aging skin. This booster was the missing piece. My brown spots have finally started to fade and my complexion is brighter after only 3 weeks of morning only use. This and the retinol booster in the evening have made the biggest difference.Been waiting for this forever. I use it nearly everyday and have seen the benefits on my skin ! :))As I am in my late 20's I didn't know how much difference this would make to my skin but I have been pleasantly surprised! I love the pipette formula which allows you to add as little or as much as you'd like to your existing skincare routine. On first application my skin was luminous and bright- looking more radiant and uniform in appearance where my pigment normally is inconsistent. I look forward to seeing the difference in my skin over time.I love this booster! I've been using it three times a week since I ordered it and my skin looks brighter and more even - my sun spots have definitely faded. I'm officially addicted.I have never used anything that felt this good on my skin. I have only been using it for a short while now but my skin has never looked brighter and more even! I have very sensitive skin but this didn't irritate at all. Really easy to use and apply, and left my skin feeling beautifully soft and radiant. Thank you Paula!!I was waiting for this product for so long. I am really it's finally here in UK. I am pretty sure it's going to be fabulous like all other PC 's product. One more thing to add in my beauty bundleOn my fourth day and already noticing a difference! It's a bit tacky at first. I put on before bed and definitely an improvement so far. I have started derma rolling and leave for an hour and then apply. Very pleasedI have only been using this product for a week but I can already see that my skin tone is more even, and it is not irritating when used in the morning. When I tried to use it on top of the AHA 8 gel it was a bit too much so I now use it straight on cleansed and toned skin and then it works great!Love this product so much! My skin is firmer and smoother. My sun damage is fading. It's my new must-have!
Customer Care Paula's Choice: Hi TJ, great to hear you love our C15 Super Booser as much as we do!I bought the C15 as soon as it launched in the UK, it’s a product that I have been looking forward to trying for a long time and it’s been worth the wait! After using it just a few times, I have seen a noticeable difference. My skin looks instantly more radiant and just ‘glowy’! I don’t think I’ve seen such dramatic effects with any other product. I’m really looking forward to seeing how it performs over a few weeks. Thanks PC for finally bringing this fab product to the UK!I have been using this product for some time but until now I had to buy it when I was on holiday in the US so I am very happy it is finally here! I have tried a couple of vitamin C serums and this one is my absolute favorite. I love how easy it is to apply this product and I like the texture and smell. I started to see some results after a few weeks and I would not want to be without this product ever again! I received so many comments on how fab my skin is looking after using this product.

Why do you recommend to use the C15 Super Booster within three months?
The C15 Super Booster contains a high concentration of vitamin C, which loses its potency when exposed to light and air. Using it within 3 months guarantees its effectiveness, when used after this period the product may not be as potent. Unopened the shelf life of C15 Super Booster is up to one year.
Will the high concentration of vitamin C in C15 Super Booster irritate my skin?
Vitamin C is not generally an ingredient that causes skin irritation, but if your skin appears red or inflamed we recommend that you reduce the frequency of use or temporarily stop.
