Clinical Skin Vitamin C Pro-Collagen Serum, Vitamin E, Anti-Aging, Skin Brightening Formula, For Soft Luminous Skin, for Fine Lines and Wrinkles

I noticed a tautness after using this serum on the first evening. I applied it after cleansing my face and it absorbed beautifully into my skin leaving no residue and my skin felt comfortable and soft. I began to notice a new resilience in my skin after using the serum for a couple days. I am in my 60's and my skin has become thinner with age and I began to feel and see an improvement in the tone and elasticity in my face and neck. My jowls appear less droopy and there is a very welcome definition around my jawbones that I hadn't seen in a while. I have to tell you, using this serum has brought back a glow that I thought was long gone. I had never thought much about the science of using vitamin c on my face but after using this serum I see the benefits and I'm very pleased with the results. The serum comes with a very informative booklet that delves into the science of the ingredients and it is very thorough and informative. I love using a product that comes with so much information from the manufacturer. This is a very high end product that provides definite results. The only thing I didn't like about the product is the color of the serum. It's a dark color that is a little off-putting. I am used to using serums that are clear but after seeing the results this serum provides you with the color of the product is of no consequence. I'm definitely recommending this product. I see very nice results that are wonderfully noticeable.

I really appreciate them offering a sample size of Vitamin C. My skin is very sensitive to Vitamin C and a lot of them break me out. It is so nice to try before committing to purchasing the large size. This is a typical Vitamin C, it doesn't smell great. But not of the good ones do... This is about a weeks worth of product. I have been using a Vitamin C serum for years, so I didn't notice any additional benefits when using this for a week, but I also didn't lose any of my progress (brightened skin, tightness, etc).

I have the large size bottle of this lovely serum that I have been using several times a week for almost a year now. I was super excited to get these sample sizes because it's a perfect for traveling or a quick weekend getaway. And it's a great skin serum that you could totally gift to yourself or a friend! This mini trial size comes in a really snazzy package with 2 deluxe samples individually boxed within and a Clinical+Skin info brochure.The vitamin C pro-collagen serum is a nice, lush oil without being sticky or tacky feeling. It has a sort of soft botanical scent that isn't strong. I have generally oily skin but this doesn't leave an overly oily or greasy feeling as it absorbs well. I like how smooth and hydrated my face feels after using the serum. Since I turned 40, I'm a lot more selective about what I put on my skin. This Clinical+Skin product is definitely welcome in my skincare routine!

Great product. Wish there was more in a bottle.

About a dozen years or so ago, I went to the community pool with my husband. We did not have sun screen and that was a horrible mistake on my part. I'm not fair skin, but I'm not far from it. After 2.5 hours, I easily had 2 degree burns - maybe more. I should have probably gone to the hospital. But after a solid month of healing, the worst thing I've gotten from it, so far, was a little bit of skin damage (sun spots) on my shoulders and cheeks. The sunspots on my cheeks make my face look dirty - like my eyeshadow has fallen. So since I have decided to take on a daily skin care routine, I thought I'd try this Clinical skin Vitamin C, etc skin brightening serum. I have been using it relatively consistently. These little mini-trial sizes actually have quite a bit in them. One dropper does my whole face. They must make it from the rinds of oranges, because its does a slightly marmalade-y citrus smell. I have been using it for a month now and I do feel like those spots are getting a bit lighter. I don't know if serums like this have the power to make sun spots go away, but they have receded into the background and if I use a little concealer, you can't see them at all.

These 2 bottles of Vitamin C serum came packaged from the manufacturer in a ridiculously huge box given the tiny size of the bottles. I used 7 drops every morning (the recommendation is 7-10 drops every morning AND evening) and the first bottle lasted me just 11 days. After using one full bottle, I cannot discern if it made any difference in my skin. Considering the outrageous price of approximately $100 per bottle, and that one bottle only lasted me 11 days using it half as often as recommended, there's no way I would order this product again.

When they say sample size, it is no joke. It is extremely tiny. Each .10 fl oz bottle will last you approximately a week. I used with no sensitivity, but would not spend $10 for a sample size.

I like this vitamin C serum a lot. I regularly use vitamin c serum as part of my morning skincare routine, and this serum seems much better than any I've used so far. It is high quality and has a little extra umph that my regular vitamin C serums don't have (maybe it's the caffeine). I do make sure to give my skin time to absorb it before applying my moisturizer and that seems to make a difference (a small hand-held fan helps a little too). Overall I like this serum a lot.
