Vitamin C B E, and Ferulic Serum - With 20% L-Ascorbic Acid (Pure Vitamin C) 1 Fluid Ounce - with Hyaluronic Acid. Helps Reduce the Appearance of Fine Lines and Wrinkles - Helps Your Skin Glow

I LOVE this serum. Much more affordable than the other high-end brand and exact dupe! Works wonders on my skin. The “hot dog” smell is normal and is due to Ferulic Acid and Ascorbic Acid combining. ALL c+E+ferulic serums smell like that (provided that it’s the combo of ascorbic acid (c) + ferulic) - even the “high-end skin***** brand). If you hate the smell, than I would suggest using a different form of c (such as MAP or SAP or THD Ascorbate) + ferulic acid. There are many on market available, but not as effective as pure Ascorbic Acid. This is my second purchase of this serum and since the results are fantastic; I will continue to re-purchase.

I’m not sure about the processing in the lab, but after reading up on it, I think this product is properly formulated and the ingredients are stable. I’ve used this before and then went on to skinceuticals and now back to this. (No breakouts or red rashes with either of the products) I can honestly say I think it’s of the same quality....possibly better because it arrived clear. I read up that vitamin c serums go yellow, then orange, then brown when they lose efficacy or basically get old. Skinceuticals arrives with a slight discoloration. I’m sure it’s still fine, but I think Biobare is fresher. Also, if I look at the ingredients, biobare has extra vit c and extra ingredients. But, I don’t know the science stuff and I know skinceuticals put a lot of research into their product...and biobare is newer. Anyway, the main thing is, my skin does look brighter and it does moisturize. I didn’t feel I had to add a moisturizer after, but I did anyway. I also use it day and night as it’s economical enough to do so....and it does make a difference. Then, a tip I found to keep the product fresh (clear). Keep it in the fridge. I got a sample bottle through skinceuticals and put this into the empty sample bottle so I don’t open and close the main bottle too often. Oxygen also breaks down the efficacy of vitamin C Lastly, it has a strange smell. But all proper vit c products have that smell and it’s gone after a few seconds. I’m leaning toward this product over skinceuticals right now. I will update if anything changes l!

This product seems to be good quality and feels good when I use it. I can’t speak to how well it works because I don’t use it consistently because it SMELLS LIKE HOT DOG WATER. It is disgusting and makes me not want to use it but feel like I have to after what I spent on it (which seems fair based on it being a dupe for skincueticals c e ferulic). I just wish someone had included that in a review before I purchased and I would’ve maybe reconsidered. I won’t be repurchasing again solely because of the smell. If you can get past that, I’m sure this is a great product.

I had been using this product for several years, then mysteriously Amazon no longer had it. But now it's back but, almost twice as expensive as it was previously. Even though the previous incarnation of this product was good, I can't justify the added cost.

I just started using this serum after switching from ZO SKIN health serum (which is fantastic, but it's $90 and doesn't last long). The first day I used it I did not read the directions and slathered it on my face and my skin ended up looking greasy (A little goes a long way). I followed the directions and only use three drops and patted it into the skin (don’t rub it across the face). It made a huge world of difference. This product works VERY well on my African American skin leaving it with a nice even glowing skin.
