  • FRESHLY MADE FOR MAXIMUM POTENCY: Unlike other pre-made Vitamin C serums that degrade on shelves for months, our C20 Ferulic Vitamin C serum is made fresh when you order. This means you receive a powerful, effective formula that delivers real results, helping your skin appear brighter, smoother, and more youthful. Made in the U.S.A. Made Fresh When Ordered with "Date Made" written on bottle—store unopened bottles in the refrigerator.

 

  • HYDRATES, PROTECTS, AND SOOTHES: Infused with Hyaluronic Acid and Ferulic Acid, this formula doesn’t just brighten; it deeply hydrates and strengthens your skin. These antioxidants help defend against environmental damage, keeping your skin healthy and smooth. Ferulic Acid reduces inflammation and signs of aging, evens out skin tone, protects against sun damage, and enhances the effects of the L-Ascorbic Acid. 

 

  • FIGHTS SIGNS OF AGING AND SUN DAMAGE: 20% L-Ascorbic Vitamin C Ferulic Acid serum is designed to help reduce fine lines, wrinkles, and dark spots caused by sun exposure. It works by boosting collagen production, improving skin texture, and restoring a healthy glow over time.

 

  • LIGHTWEIGHT, NON-GREASY, AND FAST-ABSORBING: This oil-free, water-based serum glides on effortlessly, absorbing quickly without leaving a sticky or heavy feeling. It works well under makeup and sunscreen, making it an easy addition to your daily routine.

Love it

One of the only Vit C serums I can find without Vit E (ALWAYS breaks me out) or Propranediol (too slick feeling). Affordable too. I ❤️ it!

4.0 out of 5 stars A few DIY tweaks to hopefully optimize the skin healing benefits of this serum

After years of not paying attention to my skin, I've been noticing that I'm starting to develop fine lines on my forehead. Now that I'm noticing the lines, I've also started to notice other problems including hyper pigmentation from sun exposure and old acne, as well as overall skin dehydration. After I got over being freaked out about these visible signs of aging, I've been working on creating a skin care regimen to address these issues. Vitamin C has a strong evidence base in terms of improving skin health. I've investigated DIY vitamin C formulations, and while I'm eventually going to head in the DIY direction, gathering the raw materials, containers, and measurement devices is pretty expensive. NuFountain's C20 + Ferulic is a good alternative. One of the biggest drawbacks about vitamin C serums are that they rapidly oxidize. The NuFountain formulation contains Ferulic acid which synergistically works with vitamin C to protect against oxidation in the skin, however other, more expensive formulations additionally contain vitamin E and an accompanying emulsifier. Vitamin E is an oil soluble antioxidant that stabilizes and works synergistically with water soluble vitamin C to help retard oxidation. IMHO I'm thinking the vitamin E has not been added to the NuFountain formulation because the more expensive products have patented the C+E+ferulic acid + pH range combination that is most bioavailable. NuFountain's formulation hits all the targets except the vitamin E addition, but I can work with that. Since I'm a DIYer at heart, I've made a few changes to help with the oxidation problem. The first thing I've done is wrapped the bottle with aluminum foil to decrease light exposure as much as possible. Another change I've made is I've added a few drops of a vitamin E containing oil to the top of the bottle. Since there is no emulsifier, I haven't bothered shaking it - the oil is just to create a barrier between the serum and air. (I think a few drops of mineral oil might be even more effective, as mineral oil is inert and non-comedogenic, but that's a DIY aside). When it comes time to apply the serum (right after I've washed my face with a gentle non-dehydrating cleanser) I put a few drops of my vitamin E containing oil onto the palm of my hand, then add a few drops of the NuFountain vitamin C serum, then swirl them together, and then apply to my face with my fingertips. Other reasons why I like this formulation: -I have sensitive skin that reacts poorly to lemon\orange\other citrus extracts that smell good and are often added to other formulations. The NuFountain formulation doesn't contain any of these extra fragrances or ingredients that will irritate my skin. -It contains L-ascoborbic acid, which is the form of vitamin C which has been studied the most in terms of benefits to the skin. Many of the other companies formulations that can be found on Amazon.com contain less well studied forms of vitamin C and their efficacy has not been established. -The pH formulation is optimized so that the L-ascorbic acid is bioavailable. -It's a stand alone product that I can work into my overall skincare layering system (i.e. I'm taking my cue from Korean skincare tips). Note: I paid for this product myself and was not sponsored or asked to write a review!

Use instead of Skinceuticals C & E

Skinceuticals was getting too expensive and irritated my neck. Googled replacement for Skinceuticals and this came out highly rated. No irritation and better smell. Will use again.

C20 Ferulic

This is a really well made product that delivers results... I felt and noticed a difference in my skin's texture pretty quickly. It seemed to give me a slightly "rosy" effect which I don't mind because I can get quite pale during the winter months. That "glow" does dissipate later on. I've done a lot of research on this type of product and have read that you could probably make something like this yourself for just a fraction of the cost. Maybe at some point I will try that. But, for now this product is reasonably priced (at least compared to most brands) and I believe it's just as good if not better than more expensive brands.

Best Vitamin C serum in the whole world

Best Vitamin C serum in the whole world!!! Don't know how they do it keeping it so fresh! Usually c serums get oxidized after a few days no matter how much you prevent air contact. As advised, I keep this in the fridge and as soon as I take my drops I seal it right away. I use this for my body where my skin texture became dull. In just a week my skin has brightened up and looks fresh. Ordering more!!!!
