FA LA LA LA LAAAAAAA!!!
Fa La la la la la la la laaaaaaa!!! I'VE FINALLY FOUND IT!!! I feel like I could bust out into an opera song! I am a PRODUCT JUNKIE and I have searched the world high and low for something to help with my crow's feet, smile lines, and overall skin dullness. I feel like I've tried everything: from drugstore merch to super duper expensive brands. I have a graveyard of wrinkle creams/serums that represents a LOT of wasted $. I've tried so many products that did absolutely nothing for me, and I've tried products that seemed to have helped a little bit - but nothing to write home about. After reading a million reviews, I bought the COUI Super C Serum and the COUI Vitamin C Serum 20%. I've been using them for about a month, and I'm so happy to say that I'm finally not disappointed this time! Within 3 days my skin had improved - it looked brighter and rejuvenated. I deal with adult acne, and this has also helped with that. My skin is clearer. It hasn't eliminated my acne completely, but my breakouts are diminished. My MAIN concern is my crow's feet, and this is the ONLY product I've found that has softened them. I'm sure there are other good products out there, but I think you have to find the product that works for YOU. And I have no idea why, but absolutely no other product I've tried has helped my crow's feet. (Hyaluronic acid will help temporarily for a day fix - but I'm referring to long-term.) My crow's feet haven't vanished (this isn't botox!), but I can visibly see that they are less harsh. Thank you!!! I'm hoping that with continued use it will only get better. I use the Super C 2x a day - morning and night. It's clear and light and feels refreshing. I use the Vit C 20% at bedtime every other night. It's sticky and can't be worn under makeup. It exfoliates. I also have to say that this company has got it going on! They sent me an email with information and step-by-step directions. Then today I got a coupon for future purchases with them. It's apparent that they care about what they do. Thank you COUI for making an incredible product that doesn't break my bank!!!

This is a GREAT product, I promise!
My Dermatologist recommended this for my blackheads, wrinkles, and many years of sunning as a teenager. I have been using it for about 2 weeks or so. It has already made a huge difference in my blackheads! No kidding! The wrinkles and a few dark spots will take a bit longer I'm sure, but I have confidence it this stuff! I wouldn't leave this review if I didn't believe in this stuff, I've used a ton of other products paying a lot more for a whole lot less results! I love it! I plan to use it for a long, long time or until he tells me otherwise! 3/4/15 I have been using this product for several months now and I still recommend it whole heartedly! It has so helped my complexion. I have less blackheads, my face is no longer oily in those areas it once was always. That might in part be due to my age, (63 now), but I believe this product has helped that since I was oily before using this. I don't have breakouts like I was before starting this product, and my brown spots on my face and my hands have almost disappeared! I use the product that is left from my face to rub into the back of my hands! I alternate this product with the Super C Serum which also helps with my wrinkles, I love it as well! I am one of those that if it doesn't help with that first one, I don't buy it again! So, I can honestly say this one works! Update! Dec. 8, 2014 A really great product recommended by my dermatologist. It has totally helped my complexion and my brown spots disappear ! I am really thrilled with this product and am so excited that it works so well. He told me how good it was and that amazon.com was the best place to buy it. The seller is wonderful to deal with and will answer your questions and give you guidance in using their products. I have recommended this product to all of my friends and relatives that are not already using it and now I am using the Super C also rotating it with this product and am seeing excellent results with it also. I am super happy with this company and their products, no kidding! I would not give this review otherwise.

Nice product, subtle but noticeable improvement in plumpness & softness
I'm happy I invested in this serum. I've only been using it a couple weeks, but it has helped with some dry spots, and I have felt that my skin feels younger and more 'plump' since. I'm in my early 40s with combination skin. Note: I have been using this partially in conjunction with a derma roller (the micro-needle roller for your face). I was worried this would sting if I applied immediately after using the roller, but it does not sting at all, thankfully. It also does not sting around the delicate eye area (obviously don't get it in your eyes). The bottle should last at least 6 months, I'd predict. A little goes a long way. The instructions suggest to discard after 6 months due to chemicals losing effectiveness - no idea how accurate that really is. The only very minor points I'd say aren't "wow" about the product are 1) the smell - it's not a bad smell, but not exactly nice and refreshing either. Maybe I was expecting a more citrus scent or something. 2) the stickiness - it is mildly sticky, rather than smooth, to apply. Not terrible or anything - maybe that is just how Hyaluronic Acid is (I don't know, this is my first experience with this ingredient). But your fingers and face feel a bit sticky after application, so your face won't be caressable by your partner, and you will probably feel like washing your hands. Not a big deal, but something to be aware of depending on your personal expectations. I'll keep using this, and would recommend it to a friend looking for a little extra softness and plumpness at a value price. Worth a try!

Okay but I hoped for more
I tried this out until it ran out. I was hoping for more results but I did not notice any signicant or even nearly significant changes. It did moisturize very well and I am sure it could be used to boost a regular moisturizer in the dry winter season. Overall the product was okay but I was kind of hoping for some improvement to sun damage and fine lines. I did finally get results after I went to the dermatologist and got prescrinption retinols and a product line to use in conjunction with it. I think seeing the doctor may be the only way to get you onto a path where you can get results.

Rich Nutrients for Your Skin
This product is very rewarding. It has improved my skins appearance and given it a vibrant, healthy glow. I've been using it for a couple of months now and I look forward to applying it every morning. I've always used C serum, and was using a different brand of C serum that I thought was working well, but I switched to this one because of the launch price, which is awesome BTW, but upon receiving it I found this one to have much better ingredients than the product I was using before, and upon using it I was very impressed with the way it felt on my skin and how my skin reacted to it. It is one of my favorite products now and I even purchased a couple more bottles since they were still offering the launch price and I do not want to be without it. I keep it in the refrigerator and apply it after my toner each morning as recommended. It feels so refreshing and protective to my skin. I can feel my skin drinking it in just like when I drink a big glass of freshly juiced fruits and vegetables, all those wonderful natural nutrients penetrating my cells and healing me of all of the daily toxins I encounter everyday. It soaks into my skin very quickly and leaves my skin feeling like there is a protective barrier between my skin and the sun and any free radicals that may try to enter. I ALWAYS use a moisturizing sunscreen everyday but since I've been using this product my skin has been more vibrant and brighter looking, I've also noticed that my blemishes heal faster than they used to as well as having less of them. This is really an awesome product. Do yourself a favor and use it. I think you are going to be pleasantly surprised, I was...

Not a quality Vitamin C serum
When I ran out of my usual brand of Vitamin C Serum 20%, I decided to purchase this since it was a fraction of the cost and had great reviews. Unfortunately, I was not impressed. The dark yellow color was off putting because it reminded me of an oxidized Vitamin C serum which is not good for your skin. It was a little stickier than I liked as well. But the worse part was that after just a few uses the serum seemed to be getting thicker and had some build up of something around the inside of the bottle. (I always replaced the lid highly after each use and kept out of light). Maybe I got a bad bottle? Not sure, but back to my expensive Vit C serum :(

Absolutely the BEST I have tried!
This serum is the 2nd Vitamin C serum I have ordered. The first was a different organic kind that I also rated 5 stars as it deserved it and worked very well, but that was before I tried this. This one I would rate 10 stars.Here is part of my follow up e-mail from the company: OUI Skincare Vitamin 20% is one of the few serums on the market that actually does contain a true 20% Vitamin C concentration (not an โequivalent toโ, โlikeโ etc.). We have also added more quality anti-oxidants such as Ferulic Acid, vitamin E and others, in generous amounts, in order to create a powerful anti-oxidant serum that fights the free radicals that your skin encounters daily. We chose this form of Vitamin C for our serum because of its acidity so that you can benefit from its gentle exfoliation properties. Exfoliation is important in order for skin renewal to take place. While you wonโt actually see the exfoliation you will feel it working (a slight tingling or refreshing feeling) and you will definitely see it in the results. Please note that our serum is not transparent or clear. It is a real serum loaded with maximum possible active ingredients to provide you with the best anti-oxidant and anti-aging effects. The champagne color is due to our base serum of antioxidants such as pomegranate, lemon and orange extracts, Ferulic acid etc. We do not merely fill our products with false fillers. What to expect in the first few weeks: Years of exposure to Sun and to Free-Radicals wonโt go away overnight. However, we do promise results, with constant use wrinkles and fine lines will fade and your skin will become and look healthier. Depending on your individual skin type and condition, you should expect to see an improvement very soon. When I personally tried our newly formulated serum for the first time I felt a slight tingling feeling and a few minutes later a very โplumpingโ feeling as the high concentration of Vitamin C entered my skin. This serum has noticeably given me the results I was looking for and I have only been using it for about a week. No more trying out different serums, this is the one for me :-)

... I don't think it is doing my skin any good. Having done more research
I am now on my second bottle of this product and unfortunately I don't think it is doing my skin any good. Having done more research, I discovered that the form of Vitamin C in this product is not the kind that is the most beneficial for skin. This one lists L-ascorbic acid (which is pure vitamin c) and this is known to be unstable and drying for the skin. My experience is that it burns going on and requires application of a moisturizer really quickly after applying it. According to research (as of this date) the better forms of vitamin c for the skin are Tetrahexyldecyl ascorbate or Sodium ascorbyl phosphate. I have purchased a product that lists the latter form and will see if it makes a difference. UPDATE: I have to add a comment here about this seller, who gets an A+++. I received a refund immediately within 2 days of this post without even asking for one. Please see discussion/comments following this review.

i was searching something good for my skin and to slow down aging process
i purchased coui vitamin c serum on 11 sep .i am 47 yrs old. i was searching something good for my skin and to slow down aging process.i have used vitamin c serum for the first time .this product is really good , i got it very fresh in milky colour .consistency is also good ,it spreads evenly and it has 20 %vitamin c which is needed for collagen production . i use it daily at night and in ten days i have noticed a slight uplift in my skin and i have dark pigmentation marks on my both cheeks , there is slight lightening effect on marks also . i am very happy with the effect of this serum . i am not expecting too much results in short time so i will continue this serum for two months atleast before switching over to some thing else . after noticing its effect i should say we should start using vitamin c serum at the age of 35 before wrinkles start . i am really happy that i have found some thing good on which i can depend to slow down my aging process

it was horrible. i just stopped nevermind i am not using ...
i am sorry to say this product was worth not a cent for me being this costly one expects to atleast be assured of it quality the day this product arrived , i didnt immediately used it. after a week i opened this product, what i saw was it had yellowish color. I had read somewhere that vitamin c if turned yellow it loses it effect/oxidised. i was dissappointed and contacted amazon. well i filed for product return but nothing happened so far. as i had only used it once and it had oxidised.i was skeptical to use it on face nevertheless i again applied second time (for giving second chance), the next day my face had developed spots and puss filled spots. it was horrible. i just stopped nevermind i am not using this product ....best wishes who find it excellent 30 Days "Younger Skin" 100% Money Back Guarantee!!! this is what the product says lols what a joke ....i complaint for refund and also never got a clear reply. for me oz natural worked much better it gave me really amazing glow.
