Vitamin C Serum 20% Pure L-Ascorbic Acid, Ferulic Acid, Vitamin E and Hyaluronic Acid for Face and Eyes Natural Anti Aging Anti Wrinkle 1oz. by Dr. Brenner

Works very fast. My red/dark spots fade just faster in a week then without using this serum. This is the 3rd bottle I’ve bought and I noticed it’s more oily than the other 2 but it goes away. The first 2 were lightly oxidized but my 3rd is completely clear.

I love this serum!! My skin is soft, minimum little lines. Not sure how it works but it does.

After doing some research the first product I have received had gone bad. It was brown and had a hotdog water smell to it like people say (accurate). I didn’t know any better thought that was how it was supposed to be, used the entire thing but still pleased with the results i got from that first bottle. The new one is clear and scentless. If you receive a brown one please inform them, it’s a good product if anything use it as a sign it’s the good stuff. Definitely Recommend.Updated: So after contacting the brand directly they sent this photo stating the Middle and left one are good to use if it looks like the one on Right it has completely oxidized and is no longer effective. The reason you may get one that’s brown is because amazon warehouses aren’t rotating their shipments properly but if you order directly from their site you’re guaranteed to get a fresh one.I’ll update to see how this clear one is working for me.

I do not wear makeup so the face I wake up with is the face I go out with, and since putting this serum (combined with a retinol serum) on at night, I have been loving how my skin looks when I wake up! :)I have been using this for a month so far and am very happy. The serum definitely has a smell (not perfume). I think it reminds me of just hippy oils in general; like geranium, or a more earthy flower. It’s not a good smell, but it is not pungent like a perfume either, so it is easy ignore, especially when put on at night. The serum applies smooth and absorbs into skin quickly. My face is a little shiny for about 20 minutes, but after it is dry to touch and not oily looking or feeling at all. When I wake up the next morning my skin looks and feels moisturized and when I take a shower the next night my face still has the serum on it (which is a good thing in my opinion). My eyes and face look bright and awake from the moment I wake up. It is great to feel confident about my skin without any makeup.We recently moved to the east coast and as winter started to arrive, I found my face looking and feeling very dull and loose (being in my mid twenties and from a Mediterranean climate, this was a very odd thing for me to notice every day). I started my research by asking people for recommendations on skin care for preventing aging. Many expensive products and skincare lines were brought up, so I then began to research what the active ingredients were in such products. I came to the only proven-to-be-potent active ingredients in all the products were either retinol (vitamin a) or vitamin c ( l-ascorbic acid). Going further into research by reading dermatoligicle essays and such, I found that retinol (vitamin a) and vitamin c ( in the form of l-ascorbic acid) have been studied for at least 20 years and been proven time and time again to really help with skin health, photo-aging, and lines. So, looking further into how to make vitamin c the most potent as possible, I found that vitamin c works best when paired with vitamin e, and when ferulic acid is added, the vitamin c is drastically better at protecting your skin from uva and uvb damage (when under sun screen). The hyaluronic acid is good for counteracting any drying effects the vitamin c might have and helps with absorption deeper into the skin. Vitamin c also needs to be between 15%-20% to give the best results. This serum is only 15%, but worth the compromise for all of the other ingredients and the fact that it is l-ascorbic acid and not the synthetic vitamin c that is in a lot of other vitamin c serums. Only l-ascorbic has been studied over 20 years and been found to be gentle/relatively safe on skin and work long term. The synthetic versions are more stable but due to them been rather new, long term studies are not really available yet. Finally, because vitamin c breaks down in the sun, it is best to put it on at night before bed (so it can soak into your skin in the dark and then protect it during the day). Extra bonus; if one uses retinol, putting a vitamin c serum on first improves the ability of retinol to penetrate into the skin and become more potent. This stuff is all the bang for your buck!

I noticed a difference very soon (1-2 weeks) after incorporating this into my routine. I have pink undertone skin with a lot of freckles, and I've noticed it has made my skin brighter and evened out my tone. This was the only thing that's changed in my routine, and I've woken up multiple times a bit surprised by my skin, so I figured it was time to write a review!It plays well under makeup, but it does smell really bad, so be warned. It has the hotdog water smell of similar serums. For the price, I'll definitely rebuy.I'm in my early thirties and don't have wrinkles yet, so I can't comment much on its anti aging properties.As far as vitamin C serums go, the only other ones I've tried are Timeless (no difference to skin) and Lancome Genifique (did improve skin, but was too expensive for a small difference). So I can't compare it to the SkinCeuticals one or the Maelove one people love.
