CSI Vitamin C + 12% Youth Serum - 1 fl oz

This is the simplest Vitamin C face serum I have tried (been through 2 companies not including this one) and none have made my face look this nice after just one application. I know it will only get better.Facial serums of this type take 2 weeks to see their results (evening of skin tone, skin appears and looks softer etc) and this one has done it for me. I couldn't be happier. I would recommend this to any woman interested in using this during their pregnancy (google Skin Deep).Oh for this only interested in the numbers.....Despite it not being 20% Vitamin C but 12% well that has nothing to do with the performance of this product. Quite the contrary this is hands down the best Vitamin C facial serum I have yet tried.About the price... Yeah it may be pricey (I am not into spending $20 or more for any facial serum) but this is worth every penny because instead of using the typical 8 drops per application (face and neck areas) I use 5 drops which means in the long run this product beats the competition.Anyhow great product! Just understand you have to let the product dry for 2-4 minutes before it feels right.

I am devoted to this product. After researching Vitamin C serums high and low, this is the one I chose, and it was the right choice for me. I put 3-5 drops on my fingertips and blend in. I am 35 and get told I look 25 all the time- that didn't happen before I started using this product. It is an obvious difference in my skin...it tightens and brightens my face. It has a strong smell, but it's not chemical- I enjoy the smell and it goes away after you blend it in. At first, the serum will make your skin feel pleasantly warm and tingly. I recommend putting this on a bare face so that you can get the full effect and let it sink in.*As a relevant aside, my other go-tos for good skin is pure aloe vera on a bare face 1-2 times per week for an "instant facial" that brightens, tightens and clears the skin; Also, a pure bentonite clay mask 1x week to tighten pores and clear toxins. Use this C serum or another product to keep it moisturized, as aloe and clay can have a drying effect that needs to be countered :)

It just felt like putting oil on my face. Way to greasy. It also took a long time to dry. I will not be repurchasing.

This serum is great quality! packaged well and is not at all wasteful. I was hesitant at first because the texture is almost oily (but not quite) and I was afraid it would break me out! I have been using it for a month and am happy to report no breakouts. I am only in my twenties though, so I cannot say much in the way of wrinkles and such, but I am hoping this will great for prevention. I do notice a brighter more even skin tone as well as less oil production during the day and smoother skin. Definitely try it out! I hope they never discontinue it !

A little bit goes along way, has not caused any breakouts and my skin feels more even.

I love this product! I’ve bought it for friends and family and everyone loves it! My daughter asked me (after using it twice) what I was doing differently on my face (I had not told her before I was doing anything different) and told me I looked much younger!

I’ve used this for years and my skin looks great!

I've ordered this item before and loved it. It is not the same, in texture, results or smell. The price almost doubled. I'm sad because the original product was excellent. I was not informed it was changed
