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

This is a 10/10 for me as far as Vit-C serums go. I’ve tried a lot of brands including Prequel and Timeless. This is better by a long shot. The consistency is light and a little like oil like the others, but absorbs so fast on your skin. I loved the effects of Timeless, but my face always felt like an oil slick when I put it on and it took a little long to absorb before I could put anything else on top. This is quick and keeps my morning moving while I’m getting ready for work. Just like all of them, there’s a light hotdog water smell until it dries, but it doesn’t linger. The airless pump makes such a difference over the dropper bottles. I feel like the product stays fresh, won’t oxidize as fast, and isn’t being contaminated. Even still, I keep it in a cabinet to keep it away from light. I saw some reviews to buy direct from Dr Brenner, but I had no issues from Amazon being the seller on this purchase.

*update* I am now happy this isnt Prime anymore. I tried a couple other serums with similar ingredients after this was no longer available for subscribe and save and they were awful. The other products I tried to replace this with were sticky and scented. Just terrible formulas imo. I ended up ordering Dr. Brenners again regardless of the non Prime status because I now knew this serum is superior. Ive ordered twice now where the item is shipping from what I assume is the Dr. Brenners warehouse vs an Amazon warehouse and the its obvious the formula is fresher than it was when it was on Prime. Now its always very clear and it feels more "activated" when applying. Dr. Brenners warehouse also ships it nicely wrapped in tissue paper and it feels like I am recieving a quality well packaged item. Sometimes the serum when it shipped Prime had already started to oxidize before Id even opened the bottle. As a side note, I used to use another vitamin c serum from Pauals Choice at triple the price as this serum is and Dr. Brenners is still better. This is one of the 1st and few face products Ive used where I could visibly see a difference in my skin and knew that my skin looked better as a direct result of this one product. I recommended this to a friend of mine and she noted the same thing. I love this serum and had it on subscribe and save. Im soooo sad its no longer Prime. Ugh. I've tried another brand to replace this one and there's no comparison. I used this one for about a year and my skin was noticeably brighter. Its frangrance free. I love the thin consistency. The Chemist Confession skincare chicks recommended it for the vitamin c being more stable than other comparable products. I found that to be true. It did turn sometimes before it ran out but it worked and I love it. Bring it back on Prime please!!!

Great product. I have been using it for years with great results. 4-stars because the new bottles are awful,Please bring back the option to buy the old bottle.

I’ve ordered this 15 times! 15! It’s so good, and I think even better than the expensive brands. They’ve changed the packaging to a pump so the product has less contact with air. This keeps it from degrading which was an issue in the past. I use it every day and it absorbs quickly, works well under makeup, and creates a beautiful skin tone.

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’ve been using this for about two years now. 5 stars as far as performance. Loved it…but hate the new packaging. I will always choose glass over plastic in anything I purchase. I go through this stuff so fast, it doesn’t have a chance to degrade. Please bring back the glass bottle.

Usually, I have no real expectations that a product will work. I most certainly do not sing its praises unless they are deserved. This Vitamin C oil actually does show results on my face. My skin feels sighter and smoother. Surprisingly, there is no skin irritation. Even though my skin tends to be a bit oily, this oil is instantly absorbed, and so it can be worn under makeup.

This Vitamin C serum has been a favorite of mine for years, but the company recently changed (and reduced the quality of) the container for the serum. The original packaging was a dark glass bottle with a dropper, and now it is a cheap plastic bottle with a pump dispenser. The new design has functionally ruined the experience of using the product and had compromised the serum itself. The pump catches as you press it, both spraying product in every direction and dribbling it out onto the dispenser, meaning that you have to scrape the product off the container and whatever other surface it splashes onto. You have very little control over how much serum you get with each pump, so you end up wasting quite a bit with each use. Further, the seam between the bottle and the pump is not sealed, which means that the product leaks out and pools into the cap AND that the product oxidizes rapidly. I've been using this bottle for two weeks and the serum has already become dark yellow and inert. The original glass bottle gave you full control over how much product you used, how well the bottle was sealed, and you could see exactly how much serum was left in the bottle so that none went to waste. Glass is also more environmentally sustainable and the bottle could be repurposed after the serum was finished. This new plastic bottle quite simply sucks in comparison, and is such a downgrade that I'll be switching to a different brand.

Es un excelente producto, mi piel es sensible y lo tolera bastante bien, siento el cambio al momento que me lo pongo, es la segunda vez que lo compro y estoy muy contento.

It doesn't work, I purchased in November 2018 nd still in my face no difference

This is fairly a good brand which is why this is my second bottle. I love the consistency and the texture when applied to my face. It doesn't sting even around my eyes and lips and doesn't pill with the Sunscreen i am using. Really happy with the feeling. However, i do not see any significant lightening of the acne marks and sun damaged parts of my face. I guess it will work overtime. Let us see.

Effetto luminoso e rimpolpato senza appesantire. Fa davvero la differenza, lo riacquisterò sicuramente.

This is literally an equivalent to skinceuticals….the color the texture and the effectiveness it’s just the best….I don’t see the point on buying expensive brands when u can get best formulation of vitamin C at fraction of the price
