I am 62 years old and have sensitive skin, and have been a swimmer and scuba diver for years, so I have dry skin. I also have some dark spots, loss of elasticity, a few wrinkles, but not much skin damage. I use a 30-45 SPF sun block religiously. I have found that most vitamin C skin care products can be irritating to sensitive skin, which is why I wanted to try this sample of ReCverin 50/50 ($79) for a month. Please note I am not an expert on vitamin C serums, and not that familiar with that many other forms of vitamin C products out on the market, but have tried some before without seeing many results.

This product was the kind I wanted to try as, I tend to use natural oils and serum products without a lot of chemicals or preservatives in them.


This product has vitamin C as 2.5% dehydroascorbic acid and 2.5% ascorbic acid, some water and probably some glycerin, and comes in a dark bottle (2 fl. oz). It also comes with a smaller dark brown bottle with a pop-up lid so you can pour a smaller amount in that for daily use and keep the other amount in your refrigerator to preserve the serum from oxidization. I have read that when serums are exposed to light or heat, they will oxidize and turn a yellow/brown color, and no longer be safe to use, and possibly be quite toxic. You would want to discard it if it becomes oxidized.


The bottle says to apply daily to face, neck, arms, hands or other exposed skin. I only used this product at night, after cleansing and toning. I have also heard that the daytime sun is not a good combination with vitamin C serums – not sure if it is true or not. A little bit goes a long way. 50/50 has a little sticky consistency, but is not that thick and goes on well, absorbing quickly. The only drawback for me was adding a few drops of water before applying, which is one extra step to do. The instructions say that you should use it 50/50 with water. I find it easier just to apply it directly, but with all vitamin C serums, you have to follow the instructions to see if it will irritate skin the first few times upon application, especially those with sensitive skin. Or, you should do a skin test before applying it to see if you get a reaction.

Overall, I found this serum helped in lightening my dark spots and smoothing my fine lines, especially around the eyes. It was gentle enough for the eye area. I am sure it is safe enough and might work on dry, cracked lips. Another benefit is that this product is fragrance-free and has very few ingredients, and no irritating chemicals. I also used it on the top of my hands where I have more craggy skin and age spots. I saw some visible lightening and smoothing of the hands. I would definitely recommend this product to anyone looking for a safe, natural approach to fine wrinkles, sun/age spots, or other skin problems. And ReCverin can probably be found at a more reasonable price than other serums on the market.
