While being the most expensive of Paula's serums, C15 delivers on it's promises and I will always have it on hand. From the first week of use, my skin looked more radiant, and after my first full bottle I noticed that my dark spots had disappeared! I use it in conjunction with the Resist Retinol serum. The formula is very watery and a little hard to apply because of that-I'm sure that I end up with more than the recommended 2 or 3 drops because it runs through my fingers so easily and I apply more. Yesterday two friends and I went to "makeover" party where we had to appear clean-faced with no makeup at first. My friends couldn't believe I didn't have foundation or a BB cream on! For someone with 50 year old skin, that's quite a compliment! I will never run out of C15!
I agree with the post that said that Paula's Choice products keep getting better (I am also not an employee :) First and foremost, they do not engage in or support testing on animals (which is a deal breaker for me with products). I started using her products a little over a decade ago when I was 20 and people are constantly complimenting me on my skin. Thanks to her and religious use of SPF daily since my teens, I have no wrinkles and my four younger sisters were convinced I'd had Botox & peels! My friend recommended her products because I am obsessed with researching. I love consumer reports, I lover her free beautypedia reviews, ingredient dictionary and the references to independent research for the claims she makes for her products. All that said - the C15 Super Booster is the BEST of the BEST! I am in LOVE with the way it feels on my skin, all the research behind the benefits of the C, E & Ferulic and the glow. The best part of Paula's Choice is the customer service. It is second to none. I have called over a minor issue and they bent over backwards, going above and beyond to get me what I wanted. If you are unhappy - there is no risk whatsoever.
I use this serum before bedtime on clean skin. Then I apply a Retin A cream and a moisturizer.
1. A few drops go a long way
2. It absorbs into skin easily
3. It's a fabulous formula with everything your skin wants, and nothing irritating
4. It does make my skin look brighter and more even-toned
5. Fantastic packaging
6. Zero irritation, even with all the prescription and non-prescription products I'm using
The cons: None
I suppose it is not cheap, but it can really go a long way and compared to a smilar Vit.C serum, it's practically a bargain.
This serum puts similar by Skinceuticals and Cellex-C in the shade given it is 1/3 of the price and identical, if not superior given it has a peptide in the formulation, to competing serums. It mixes well with PC moisturizers and that's how I apply it every night.
In a few weeks my skin is clearer, brighter, smoother, less red and the few brown spots I have have faded. Basically, this serum is great and it works.
I happen to purchase this when it was on sale. I am seriously in love with this stuff. I found the best way to apply it is to mix 4 drops into my PC Antioxidant Serum and pat it into my skin. The first try I mixed 4 drops into my PC Hydralight SPF 30 and was noticing some separation and flaking upon application. Now that I have figured out how to apply this, I couldn't be happier with the results. I have some minor redness on my left cheek (IDK Y?), but this has significantly diminished over time. It is a welcome addition to my skin care regimen. It feels good to do something good for your skin. I have tried the more expensive CE Ferulic and found that to be so irritating to my sensitive skin. Most of Paula's Choice products have been wonderful for my sensitive skin. So far I have replaced all my skin care products with her line. If you have experienced sensitivity to other brands I suggest you try this. I honestly never thought I could ever use this added addition to my skin care.
Other than my Clarisonic Mia2 ,this is the most expesive thing in my beauty aresnal and it's worth it! Buy it when it's on sale or get a sample size, PC always has sales. why pay full price? :)
It's liquidy, not sticky on skin and blends well with the RESIST Retinol Serum.
This product has helped with my undereye circles!!! Nothing I've ever tried has made much of a difference in that area. My under eye circles are herditary but also become darker when I don't get enough sleep, too much caffiene, stress, etc.
This does brighten up the skin, although I really think results would also depending on what else you are using on your skin.
If you are not using some sort of sun protection everyday, then all of these products are mostly pointless because they are trying to reverse/heal/prevent sun damage.
How I use it: 3 dots of the RESIST retinol serum on my face, then 3-4 drops of the Vit C in hands then spread it onto face, blending it with the retinol. I have oily and senstive skin, this works for me with no breakouts or irratation. Drier skintypes or people with more sun damage may require more product. I like my freckles but just wanted a better glow to my skin so I feel this is working for me. My beauty goal is skin that requires little to no foundation. I hate the way it feels on my skin. I feel like in the past 6 months of using PC products, my skin looks better and I feel more comfortable not wearing fondation on a daily basis. HTH!!
I was looking for other products to use as I'm on obagi maintenance. Due to heavy makeup usage my pores started getting congested a few months ago and I started breaking out again, so I got a bunch of PC products to try, and this is my favorite of the lot.
I've used this for about 6 weeks now and have had the same results that many of the reviewers describe---overall luminosity, more even skin tone, smaller pores, slightly faded freckles. It also seems to heal the dry flaky patches that Retin A + blender causes.The texture is very nice. I pour about 5 drops into my palm then quickly spread it out over my entire face and pat a little. The scent is similar to skinceautical's CE ferulic (similar ingredients I think). After it dries it's not sticky and has no scent. I follow with the resist ultralight which has the same watery texture.
Compared to about 6 years ago when I last ordered PC products, I feel they have improved greatly. For one thing the new watery textures are highly agreeable to my skin, they sink in and disappear and don't interfere with my makeup application. Results are more apparent. My skin was decongested in a few weeks.The products have no added fragrance but the natural scents are quite pleasing. For instance I really like the slight citrusy scent of the skin recovery antioxidant serum with retinol. So, thumbs up! I will probably use lifelong unless they reformulate for the worse.
I've been waiting a while to post this review because, unlike with a cleanser, it is not something you can use a few times and determine how well it works. It takes weeks to months to see positive changes in your skin. It's only taken me a few weeks to see brighter, plumper, smoother skin and less noticeable dark circles under my eyes, but I should note that I'd not been using any anti-aging products at all when I started with the RESIST C15 Super Booster. Also, something to keep in mind, I started using PC's antioxidant serums at the same time (mainly the ultra-light one, as I bought a full size of that, but I did try samples of the other three, also), and occasionally used PC's retinol serum and BHA 1% lotion to see well I could tolerate them. Nevertheless, I attribute the aforementioned affects of my skin to this product alone as I believe the antioxidant serums would mostly soothe and I haven't yet been able to use any of the anti-aging stuff consistently enough or long enough (due to my skin sensitivity) for them to be responsible for the effects seen. This item is on the pricier side for a PC product but not when you know how hard it is to keep Vitamin C stable and at the right ph to be effective for skin. I can see high-end lines charging much more, so I think this is a bargain!
I really like this and it really boosts the PC serums. I like it especially with the Resist ultra light, which as niacinamide in it, for fading brown spots. I use them at night. I use the regular resist, but the results were less noticeable. I also think it boosts the resist hydrator, which has a little retinol. That is making my skin smoother. I never found the PC serums without retinol did much, though I liked knowing they were there. I don't tolerate much retinol alas. So to have something that finally does something besides the AHAs, is great. The changes: brown spots are faded, skin is less irritated, stronger, smoother. I am trying it with the intense retinol serum tonight. My skin is less fussy.
The texture is watery and the color yellow. Feels a bit stingy like you had lemon on your face, but is not irritating and that tingling fades. It is not irritating my face, which can get irritated easily. I use the anti redness Instant Calm from PC and that has really calmed my skin down in general. When you add this to a cream or serum it will spread further. It makes the silicone serums thiner, which some might like. Do keep out of your eyes, that would really sting
My main complaint is that this booster isn't already in those other products or cheaper. Maybe it should come in cheaper AO combo pack. As PC adds aos to every product,, so to have to use a serum and a booster to get full results can really add up to a lot of $$ and products. Other cos sell more expensive serums and multiple ones. So its worth it to me.
I've just been using this for about a week but I'm very happy so far. My skin was breaking out a few weeks ago and I have a tendency to get exczema. I also have some light sun spots. I bought the trial size bottle because I'm cautious. I do like & use other Paula's choice skincare.
So for a week I've been using this serum once or twice a day. Using it at night I put moisturizer over it. It seems to make my pores smaller and my skin look more supple. No new breakouts. No exczema flare ups. So I've ordered the regular size bottle.
