This is a solid Vitamin C Serum (of which there are TONS on the market) and it's at a great price. My friend (who has a PhD in chemistry from a major T1 research institution) and I tested it with brand new litmus pH strips. The bottle I received and have been using for months registered a pH of 2.5. The reviewer whose strips registered a 7.5 (though it looks closer to 8.5 in that photo) might want to try again with a fresh pack of testing strips because something very weird is going on there. Additionally a serum isn't defined by viscosity but by the lack of ingredients that keep water from evaporating, such as petroleum, so I'm unsure as to the reason behind that review and claims. Serums just need to be used in a timely fashion or kept in the fridge.
I recently bought Cosmedica's hyaluronic acid serum and was pleased enough with the product that I decided to give this 20% Hydra C Serum a try.The Vitamin C serum is not a serum. Instead, it is extremely watery. To be exact, it is a translucent milky color with an odd smell that I can't put my finger on. The first listed ingredient is essentially herbal water. There is no viscosity that would indicate this product has hyaluronic acid in it, as the product headline states. As other reviewers have mentioned, this comes in a pump bottle, making it difficult to control how much product dispenses. The product absorbs quickly and there is a slight pinkish flush to the face right after application, which is indicative of Vitamin C products, but I experienced no peeling or tingling with this solution as I normally do with high percentage Vitamin C. I'm not referring to major peeling like one would experience with a glycolic acid pee, rather, light flakey peeling around say, a dried up pimple. I began to question whether this really has 20% Vitamin C content. Another product I had finished up right before buying this one, had only 15% Vitamin C, and I did experience slight peeling and tingling with it.Tonight, as I was making my DIY serum, I realized I should use my pH strips to test this product. A 20% Vitamin C solution, to be effective, should have a pH of about 2.5-3.5. On it's own, Vitamin C (l-ascorbic acid, specifically) has a pH below 2. In comparison, water has a neutral pH of ~7. This product: 7.5.I'm not sure how a "serum" that is supposed to have 20% of Vitamic C, a well known ACID, has a pH that is more alkaline than water. While I have no other way of testing percentages, I'm gathering this has .5% (less than 1%) Vitamin C in it to be more alkaline than water, which completely negates the benefits of Vitamin C.Major fail.
I use this Co a lot. This Vitamin C serum used to smell like citus. Beautiful ! Lately, it smells like garlic. I agree with others who say it now has a funny scent.
Enjoyed the refreshing scent and sensation! It smoothes on my skin so well!
Love this vitamin C serum! Hydrates penetrates well does not leave a sticky residue leaves, face feeling hydrated and smooth.
I got a vit C burn from this product. Please read about vitamin C before using. This product definitely has Vitamin C in it but make sure your skin is prepared for a high dose of this topical solution. Great product if you educate yourself first.
It hasn't gotten rid of my dark spots yet I've been using it for a couple months
Nunca había comprado una vitamina c q realmente sintieras el aroma del cítrico súper de veras un producto excelente
This serum not only works wonders, it smells amazing too! I love the viscosity of this serum, and the way it dissipates on my skin. I use it with other products from Cosmedica, and people have been remarking how great my skin is looking, so that says a lot!
Product was recommended by the woman who gives me facials once a month. She said it would reduce the size of my pores and help with blackheads. She was right! After one month of daily use pores were noticeably smaller and I had fewer blackheads. Now after 6 months I hardly have any blackheads at all and my skin is much smoother.
I love this serum and have been using since fall 2018. I put on in the AM after washing my face, then a moisturizer with spf over it. I alternate monthly between this serum and Cosmedica’s Hyralonic acid serum. This company is great and I love so many of their products. The only thing I would change is the bottle pump. It squirts the product out with a lot of force so it gets all over my sink and walls if I don’t cup my hand over the pump. Should be changed to a medicine dropper like the Hyralonic acid bottle.
Okay, so, I'm not a huge skin care guy but after turning forty last August and noticing the smile lines and crows feet getting more and more apparent, well, it was time to try something. I found that much of what's out there costs a fortune.... and then I stumbled upon Cosmedica. I was impressed and not only the great reviews, but the awesome price. I ordered a bottle of then Vitamin C Serum and after just a few weeks, I noticed a significant difference. Quite simply, my smile lines and crows feet are almost non existent. A girlfriend of mine even asked if I'd had a procedure done! Haha. You can bet I'll keep up with this stuff!!
This product gave me acne! I have extremely dry sensitive skin, and don't usually get many pimples--maybe one every few weeks near my hairline if I use oily hair products. I started using this serum and within a couple days noticed a pimple forming. So I stopped using it, got rid of the pimple, and started again. Everything was fine for a couple weeks...until I realized I had all these little clear bumps on my forehead! I have never had anything like that! There were dozens of them! This was the only change in my skincare regimen, so I immediately stopped using the product and tried zit treatments, but they didn't effect them. I figured the serum must have blocked up my pores, so I did a face mask and started exfoliating...and started getting zit after zit! I have since had two professional facials and several face masks and nothing helps: as soon as one starts to go down, more appear! Every one of the little white bumps in becoming a big angry red zit! So, if you have sensitive skin, I echo a previous poster: use with caution! I am giving two stars since the company itself gave good service, and maybe the product would be okay for someone without dry/sensitive skin.
This is a great price for a good 20% C serum that contains Ferulic Acid. I have used the Paula Dorf and the Timeless Brands and this is just as good, if not better, as far as I can tell, and a much better price. I have been using it very morning (I use prescription Retin A every night) and I am convinced that it does make a difference. I am convinced that tretinoin, Vitamin C serum and consistent use of sunscreen are the three (and virtually the only three) topicals that make a difference and none of them has to cost a fortune. This C Serum is a good value and I will repurchase.
I really can't say enough good things about this product or Cosmedica. It really works. I am not a skincare product junkie, but I have had the opportunity to try some really expensive products that made bold claims but DID NOT WORK. This product does. It doesn't happen immediately, but no product can reverse sun/environment damage overnight. I started noticing subtle brightening after about 2 weeks. I thought I was imagining things, but I wasn't. Still, I waited to post this until now. I have been using this product for about 7 months and I will continue. I am also using their retinol serum, their hyaluronic serum, and their toner. I love them all, and I am extremely impressed by their company. I am grateful that such a company even exists these days. They make excellent products that really deliver, and they are completely affordable. This bottle lasts me about 5-6 weeks.
I will continue to use this serum along with the pure hyaluronic serum from this same company. I've learned quite a bit from my esthetician and vit c serum is a great antioxidant for every day use along with a SPF 30 or more. I also apply the pure hyaluronic acid serum over this vit c daily & then at night before my peptide/hyaluronic acid night cream (Derma e) all natural product. I am 50 yrs old & have been told ALOT this past year that I look like I'm in my mid-30s. Have to say that always feels awesome! I use several other products as well. I will always try to keep up on what is best for my skin as I age. I hope this info helps.
I have a rare autoimmune disease called "Sjogren's Disease". Sjogren's attacks the moisture producing glands in your body among other not so great things. My friend who works in the skincare industry highly recommended this product. I had been using straight Moroccan Oil and different types of oil on my face to no avail. I tried this product and it has made a huge impact on my skin. I use the Cosmedica serum first and then I follow up with a product that esthetician use for treating patients after they have fractional laser therapy. Combind both products have a a big difference in my face.
I had previously purchased the Cosmedica Hyaluronic Acid, and after reading reviews that this blend of Vit. C, E, and Hyaluronic acid worked even better, I splurged on spending the $25 for it. Sadly, it seems to make my acne flare up. I'm going to have to stick with their Hyaluronic Acid, which is wonderful for my skin, and only use this about once a week. Although this isn't something I can use everyday, it has a great consistency, absorbs quickly, and helps provide moisture.
I am a bit of a skincare junky and have tried many products from cheap to expensive. I was looking for a serum that wasn't $75.00 to $150.00 as so many are. After researching the company online and reading the reviews, I will describe the product and give my opinion of it and how well it worked. I am 49 years old, have oily skin and, live in a humid climate so I have always taken excellent care of my skin. I have a microdermabrasion and a beta peel every six weeks. With that said, my skin loved this product. It is a serum that has a gel like consistency that went on smooth without stinging or causing redness. There was no fragrance or film left on my face. For those of you who said it made no difference, I wonder If having at least a lactic acid peel first would help with the effectiveness of the product. Lactic acid is very mild and safe for most people. This helps remove dead skin and helps remove spots. It takes time to see results especially if there has been a lot of sun damage and neglect to the skin. I keep mine in a wine refrigerator to preserve the integrity of the product. I will continue to use this as I find it to work well and the price is fabulous. Many of the high end products are overpriced. I hope this review helped, feel free to ask questions if needed.
I've been using the Cosmetica Vitamin C Serum with Vit E and Hyaluronic Acid going on nearly four weeks. This product delivers 100%! I am 38 years old, and regretfully, I had CO2 Fractional Laser in April to treat minor fine lines. After the treatment, my pores became more pronounced, my skin less firm, my youthful plumpness went away, and my skin tone became uneven. After using a 0.05% retinol based cream for six months per MD recommendation to speed up the healing process and after it failed to help, I didn't have faith in anything. I remembered an aesthetician once told me years back that Vitamin C is vital to use in conjunction with my moisturizers, so I decided to buy this cream after reviewing several brands. Let me tell you (crying after all I went through), this product made me feel and look human again. My pores have nearly disappeared, my skin looks brighter, and I have my cheeks back! Ladies, don't let the price misguide you. It worked for me, and this product will continue to be part of my daily regimen.
