Cosmesis Vitamin C Serum: Rejuvenate & Protect Skin with 12% Concentrated Vitamin C & Antioxidant Tea Extracts for Brighter, Healthier Skin - 1 fl oz.

This helps fade my age spots on my face and I think it helps rejuvenates my skin!

I like this product and have used it for a couple years. It leaves the skin on my face feeling very nice throughout the day. I plan on using it as long as it is available.

Cosmesis Vitamin C Serum: Rejuvenate & Protect Skin with 12% Concentrated Vitamin C is a highly moisturizing vitamin C serum. I've been fairly routine about using this for the past for days, and I've really been noticing that my skin has been looking smooth and bright. We recently moved, and the difference in water is playing havoc with my skin. However, using this serum is helping get my skin under control.To me it feels very moisturizing, and when I put it on, it takes longer than most serums to sink into my skin. That said, it does sink it after a minute or two, and the rest of the day, my skin feels very soft and supple. I've noticed that my skin looks plumper and less "tired".I realize the price point for this is fairly high, but this is one serum I think is worth the splurge. It takes very little to cover my entire face--as a matter of fact, only about one large drop is needed to drop into my hand. I then rub my hands together, coating them, and then I press the serum into my skin. I do have to wait a little longer before applying moisturizer after this product, but there's nothing greasy or oily about it.Highly recommended.

I have used quite a few of the Cosmesis facial skin care products and they are all formulated by dermatologists. Every product of theirs that I have tried has worked effectively and extremely well in providing me with younger, healthier skin and this product is also very beneficial in rejuvenating the skin. Being a senior, at my age, I'm not looking for miracles, but I have been using this Vitamin C Serum daily and nightly before applying my moisturizer, and I have noticed a slight lightening of my sunspots, and fewer lines on my face. It has also given me a nice healthy glow and slight tightening on my face and neck areas. When I apply it after cleansing my face, I have noticed a slight warmth and assume it's the Vitamin C. Only a few drops are necessary. It's a little oilier than most serums I have used, but it is absorbed into the skin after a few minutes. I would highly recommend this product to anyone who is looking for a high-end anti-aging product.

This Vitamin C serum smells a lot like others that I’ve tried before, but with this one the scent isn’t quite as strong. If you have used a Vitamin C Serum before, you know that it has a bit of an earthy odor to it - not offensive, but not perfumed either.This serum is a clear liquid and the instructions say to use 2 to 3 drops and massage it into the skin. Unlike other similar serums I’ve used it, this has more of an oily feel to it (Is that the Butylene Glycol?). I like the consistency, although it surprised me. After application it did take a few minutes for it to soak into my skin so I waited a little bit before I followed up with my moisturizer. It does a great job of hydrating and smoothing the skin short term. It's a bit too early to see any longer term results like brightening yet though.The active ingredients are 12% L-Ascorbic Acid, Butylene Glycol (for moisture retention) and Tea Concentrate (No details on what the tea concentrate contains :-(. This product is a more reasonable option than some similar products that cost 2-3x more. Albeit the competition does have a slightly higher concentration of L-Ascorbic Acid (15%) and some other active ingredients. At this price point, I feel like this 12% serum is a very good option.

As a person with very pale, sensitive, dry skin I've been doing my best to take care of it for a long time now.I mean, I burn and freckle if I just think of the sun too long and even a perfume with a heavy fragrance can cause my skin to be irritated.So the positives :This product comes in a tinted glass bottle as most Vitamin C serums do. It has no real smell or added fragrance. It seems to be fairly hydrating/moisturizing, which is a little unusual for Vitamin C but it's another point in its favor for me. I've had no irritation or breakouts after using it for a few weeks. My skin looks healthy and clear.Minor negatives:The price is the biggest thing I'm hung up on. This product has shown results, but not more than my previous Vitamin C serum which was about half the price. For me to want to pay 70$ for this in the future it would need to be either amazingly effective or at least a larger quantity.I don't hate it, but I don't love it either.

Smells awful and leaves a sticky feeling on the skin.

I have extremely dry skin, and as I've gotten older I have found that I'm getting more wrinkles than I want. I needed a good serum to moisturize my face. Over the years I have bought several different kinds, in particular the expensive stuff from large cosmetic companies. I decided to give this one a try because my skin has been especially dry throughout the summer and also to save a bit of money rather than buying the expensive serums again. This one is a bit thick and it does take a while to sink in, but I am happy with the feeling it gives me of hydrating my skin. I have used things in the past like Vitamin E oil and even petroleum jelly to try to keep my skin moisturized, but I believe this serum will do just as well as the expensive brands and the other products I have used. So far I am very pleased with it.
