I've been using Endor products for years, and they never disappoint.
I'm really liking the vitamin C serum; little by little, it's evening out my skin tone and lightening my dark spots. As with everything, consistency is key, and I make sure to use the sunscreen, which is fantastic.
The first images show very slight oxidation of vitamin C; although the orange color indicates that it has retained much of its effectiveness, it has already undergone significant oxidation. A conventional vitamin C serum that is highly oxidized takes on a dark brown color.
You be the judge.
Best regards.
Hi Emily, the serum has a perfectly normal color and is in perfect condition. No matter how hard we try to keep vitamin C stable, it’s not an inert molecule and always undergoes a small degree of oxidation. I can’t include photos in a reply to a message, but I’ve created a new post below showing evidence of our serum’s oxidation after weeks of exposure to sunlight—where it takes on a slight yellow tint (equivalent to approximately 1% oxidized vitamin C)—as well as the orange-brown color it develops when high concentrations of vitamin C have oxidized significantly.
I’ve been using the serum every day for several weeks now. It’s convenient because it absorbs pretty quickly and doesn’t leave a heavy feeling. That said, I haven’t noticed any changes in my skin: no more glow, no tighter pores, no more even skin tone, and no reduction or fading of dark spots… I’ll keep using it until I finish the product, to see if anything changes.
Hi Belén, a few weeks isn’t long enough to see results in terms of an even skin tone and dark spots. Pores don’t open or close; if you notice any irregularities, they must have a different cause. If you contact us by email, we can help you identify them. The serum doesn’t provide a “glow” as it’s typically understood in cosmetics—we state this right in the product description. A “glow” is an attractive effect, but it’s merely superficial. What we aim for is to achieve changes in the skin that result in a more natural radiance. We’ll stay in touch to hear how things are going for you.
Hi, my skin tone has evened out—I love the healthy glow it gives me, even though the spots are still there. Thank you for what you do, and good luck with the award—you deserve it.
The new VC 15 Serum is great; I'm starting to see the results little by little. I use it along with the sunscreen, and they work really well together. My next purchase will be the moisturizer for dry skin. Best regards
After using it every morning for a month, my skin is starting to clear up, and the sunspots and age spots are beginning to fade. I’ll definitely keep using it.

Quick-drying serum that leaves skin with a glow and makes it visibly more radiant
It is one of the best brands on the market
I bought this serum as soon as it became available. I’ve been using it for about a month now, and my skin feels more vibrant and “relaxed.” I simply love it, and I’m now confident enough to go out without makeup, showing off my bare skin. It’s a wonderful feeling. I can’t imagine buying other brands anymore.

I’m 66 years old, and after years of trying practically everything to improve my skin—creams of different brands and price ranges, cosmetic treatments, and even products highly recommended on social media—I ended up quite disappointed because almost nothing delivered the results it promised.
I discovered Endor, listened to Joaquín, and he convinced me—if only because of the cause to which they dedicate the proceeds from their product sales: cancer. I decided that even if it didn’t work, at least I’d be contributing in some way to the fight against this terrible disease. That’s why I started trying their products—specifically this vitamin C serum—though my expectations were pretty low. I’ve been using it for about a month and a half, and honestly, it’s been one of the few times I’ve noticed real, gradual changes in my skin.
The formula hasn’t irritated me at all; the texture is light, it absorbs quickly, and leaves a luminous finish without feeling greasy or sticky.
What I’ve noticed most is the radiance and more even appearance of my face. My skin looks more rested and has a better overall tone. Some fine lines have also gradually softened, though there were no immediate miracles. Plus, it has no scent at all—unlike many vitamin C products.
Obviously, it’s not a magic product, but precisely because I’ve tried so many products before, I think I can say that this one does make a visible difference.
I’m now a die-hard fan.
In just a few days, my skin responded amazingly to this vitamin C serum. I’m 60 years old with dry, sensitive skin. But it works wonders for my skin. It’s amazing how, right from the start, you can see that my skin looks more even, radiant, and “clear.” I bought it as soon as it came out, and I still have some left! A little goes a long way. That said, I’m already thinking about buying another one, along with my favorite creams that just came out. Honestly, I’ve never tried anything like it. Amazing!
The light brown serum is running out—does that mean it's no longer effective…? Do I have to throw it away and buy another bottle…?
Hi Emily, the stability of vitamin C is a complex issue. To ensure optimal stability, 100% of our vitamin C is stabilized and packaged in airless, opaque containers, using a formula designed to promote the stability of vitamin C.
However, vitamin C is very unstable, and even if all precautions are taken, we cannot guarantee that it won’t oxidize to some extent. Even 1% oxidation can cause the color to turn slightly yellow, but that’s not what you’re describing. You say it’s brown. Please send us the serum so we can examine it, and we’ll provide the best solution. If we need to send you a replacement, we’ll do so immediately, but we’d like to analyze the situation first.
I’d like to take this opportunity to mention that it’s highly recommended to store the container in a cool place, avoid exposing it to high temperatures, and not leave it unused at home for several months. Exposure to high temperatures greatly accelerates oxidation.
Greetings
I love this cream. It has a velvety texture—it melts into the skin but isn't greasy. I'll definitely buy it again.
All of Endor's creams are wonderful. And these cleansers are very gentle and very effective.
You can really tell the difference after just a short time of using it. A wonderful cream
After 4 weeks of consistent use, I can say that the small brown spot I had on my eyelid has disappeared—I’m not sure if it was melasma or just age-related. After many failed attempts with other products, this serum has worked. Aside from improving skin tone and radiance, I haven’t found anything like this new ENDOR serum. I’ve always said that paying a little more is money well spent—it’s a total win.

It has a really nice texture; I really like how it makes my skin feel. I love all the creams and cleansers.
After using it for a couple of months, I’ve noticed that the brown spots that had appeared on my face and neck (I’m 60 years old) due to unprotected sun exposure this spring have faded significantly, and no new ones have appeared. Now I religiously use the VC15 serum after cleansing with Pure Cleansing and P-Biotic Toner, followed by the Anti-aging Serum and Lasergen Cream, and finally SPF 50 sunscreen.
I’m thrilled with this serum and the look of my skin!! Thank you, Endor T.
It has a wonderful texture and really brightens the skin. I always use it with SPF 50. I'm really loving the results!
Hi!!! It's amazing 🙌—it's going great. I wear it every day. I love it 🥰. Kisses 💋
I've been using the serum for a month, and my skin's tone and firmness have improved.
I love this serum
I'm finishing up my first treatment and my skin feels brighter and firmer. I'll definitely buy it again
I’d been looking for a serum to help improve the appearance of my skin for a while, and honestly, Endor Technologies’ VC15 Serum has really impressed me. After using it for several weeks, I’ve noticed that a dark spot I had has faded significantly, and my skin looks more even-toned and radiant.
I'm really glad I decided to give it a try because, in my case, I've seen real results. Plus, it's a pleasant product to use and easy to incorporate into my daily routine.
I'm sharing this because it's worked really well for me, and it might be a good option for anyone looking to improve minor blemishes or brighten their skin.
