## Description

desertcart.com: 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 : Beauty & Personal Care

Review: Vitamin C Affordable Excellence - First and foremost, we all know that 20% potency is where it's at for Vitamin C serums and this delivers just that. It has noticeably helped brighten and even out my skin, especially pesky leftover marks from the occasional breakouts I still get. I also believe the addition of Ferulic Acid and Vitamin E enhances its effectiveness, providing that extra shield against free radicals. Honestly I'm just playing the long game and hoping these benefits prove true in time, ha! Comparing this serum to the much more expensive Skinceuticals alternative, I can confidently say this much more budget-friendly option holds its own. The ingredients list is nearly identical as you'll find on SkinSkool which is what drove me to try this. It was perfectly clear on arrival and has that classic Vitamin C serum scent, IYKYK. I've had it about 6 weeks now and the formula still hasn't taken on that darkening amber color so I trust that the batches are fresh and production quality is high with this brand. Will purchase again and not have to feel so bad about using it on both my face and décolletage given the price point!
Review: Stable and brightening - *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 desertcart 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!!!

## Questions & Answers

**Q: What is the percent of vitamin C?**
A: Hi, our formula contains 15% pure vitamin C (L-ascorbic acid), 1% vitamin E (tocopherol), and 0.5% ferulic acid and a 3.2 pH which is the most effective combination. It is very important to use the correct form of vitamin C and have the proper pH, you can have higher concentrations of these actives in other forms and they will not be effective. There is some very useful information on the SkinCeuticals site about C E and Ferulic and they have of course helped develop this formula.

**Q: If my moisturizer has hydraulic acid, can I still use it after applying this serum?**
A: Yes, you can use your moisturizer with Hyaluronic acid on top of this serum. (This answer is from an licensed esthetician/skin care specialist)

**Q: Just received and followed directions.  It’s so        sticky on my face!!!! I hate that.  Has anyone else had this issue?**
A: I understand.  I only apply it to my "sun spots" - but it DOES feel a little sticky!  However, the sunspots on my face and hands have almost disappeared … so I am willing to make the trade-off.

**Q: Is this product vegan and cruelty free?**
A: Yes, this product is vegan and cruelty free.

### ⭐⭐⭐⭐ Love!!!
*by C***S on February 21, 2018*

Love!! I’ve tried a ton of vitamin C serums and I never really noticed any kind of difference with them but I had come across this one on a medical blog. I have a thyroid problem that makes me have really bad hormonal cystic break outs and it recommend trying this to help prevent break out and fade scars/dark spots. I noticed a HUGE difference after one night of using this!! I wish I would have taken pictures but I didn’t expect it to work so well. I told all my friends to go buy it too. I also recently started using a derma roller (also bought on amazon) with this and literally the next day I’m shocked at how even and toned my skin looks. I subtracted 1 star because even though the product is effective I’m really not a fan of the texture. The serum is sticky which makes it hard to apply and I usually have to wash my hands after because they are also sticky. When I apply the serum I usually have to do it with a night moisturizer or another oil, and sometimes the extra oil makes me have a white head or two the next morning. Nothing serious just the really small kind that scratched off without leaving any kind of mark. But because of the sticky ness of the serum I’m not able to put it on during the day time because it makes my makeup/primer not stick to my skin and almost like peel off? But all that aside it is still awesome and totally worth it and I just keep using it at night stil! Can’t wait to try other dr. Brenner products now!
