Love how smooth this glides on. Leaves skin refreshed and moist. Nice and lightweight. Absorbs beautifully. Great value.

Best C serum I have tried
I’m on my fourth bottle. I have tried several other brands but they oxidize quickly. The pump keeps oxygen from getting in which slows any oxidation. It works well and fades my brown spots beautifully. It also gives me a wonderful glow even after a freshly cleansed face. It has all the important ingredients without the insane price. Love it!

Good vitamin C serum for daily use.
“I've been using this vitamin C serum for several weeks and I've really liked it. The texture is light, it absorbs quickly, and it doesn't leave my skin feeling sticky. My skin looks brighter and has a more even tone. It hasn't caused any irritation, even though I have sensitive skin. The packaging is practical, and a little goes a long way. I would definitely buy it again and recommend it for a daily routine.”

Great Vitamin C, but the packaging needs improvement
This is honestly one of the best Vitamin C serums I’ve tried so far. It feels light, absorbs quickly, and I’ve noticed real improvements in my skin. However, the packaging is not practical. It doesn’t come with a dropper, and the oil comes out with too much pressure, causing it to spill everywhere. If I apply it directly to my face, it runs into my eyes, and if I pour it into my hand, a lot of product is wasted because it squeezes out too fast. I definitely recommend switching the bottle to a dropper design to help prevent product loss. That’s the only thing that would make me think twice before repurchasing.

Great product
I really love this serum. I’ve bought it twice, the first time it smelled nice but this second time it has a weird smell. However, the absorbency and skin improvement are worth the few seconds of smell.

Works on sun damaged and aging skin, especially together with derma roller
(update Sept 2015: continue to use this and have tried competitor products, it works and I am quite old! but skin looking good!) Reputable dermatologists say there are only a few active ingredients out there that are proven to do anything beneficial for the skin besides moisturize it (which Crisco or vaseline could do too!) , no matter what hype the cosmetic companies put out. One of those is vitamin C. (Caution: don't use a Vit C product at the same time as Retinols (Retin A or OTC Retinol products like Roc etc), or Glycolic acids, or beta acids (salicylic etc). Use the Vit C in the a.m. and the others in the PM, sometimes even that will be too irritating for some skins. At the least put a few hours between applications of acidic products!). I heard about this product first on a skin care forum I belong to, as I am a sort of hobby aesthetician and makeup artist and always looking for something to help my own aging skin. I use a derma roller (many brands and most are about the same, needle size is the key difference), and this product used in concert with it really has helped stimulate collagen (the disappearance which is what causes skin to look 'aged' , when the padding beneath the surface begins to degrade and so the skin hangs like an empty balloon). I have been using it off and on for several months, and also got some for sisters and friends. In everyone's case I have seen an improvement in skin tone, and definitely a subtle 'plumping' effect. It's not a miraculous overnight remedy, (nothing like that exists in a bottle!), but it does help over time, and you'll see some difference within a couple weeks. Also important is that the manufacturer is using a DARK glass bottle. First because Vitamin C breaks down with exposure to light, and also because if it were plastic container, the acidity would cause some leaching of plastic byproducts into the gel. The viscous feeling of this product is due to the hyaluronic acid in it. Hyaluronic acid is the same substance (but in sterile form and at a different molecular density), that is in fillers like restylane, and that also occurs naturally in the human body. It can't really penetrate below the dermis, but with the derma rolling process, I believe a little of it can make its way in, and that it aids in plumping effect. A great value and reputable supplier. The reality is these active ingredients wholesale at a minimal cost, and the big brand names are marking them up by ridiculous amounts and creating elaborate marketing campaigns and photoshopped images of 22 year old models, and many consumers fall for the hype and believe the cost is justified; and while this product isn't 'cheap', it is moderately priced compared to department store brands, and it lasts a good while as you only need a few drops each time. I also have recommended for those starting a skin improvement regimen to take a few good before and after pictures (spaced a few months apart at least, then periodically) or have a friend do so. Then you can apply 'high def' photographic effects to the before and afters shots, which will reveal the damaged skin that the naked eye can't detect, and subsequent improvement (or lack thereof!), in great (often disturbing! detail). (There are free programs online that can do this(ipiccy is one), or if you use photoshop etc, that allow you to increase detail in your skin - usually called something like 'high def', 'gritty' etc). Department store makeup counters used to have these boxes with special lights and mirror that you'd put your face in and would reveal the sun damage that is not apparent to the naked eye - using as a selling tool-- this HDR effect does the same basic thing - reveal what the naked eye can't see but which IS there! The proof was there for me that my skin was looking better, less damaged. In my case the derma roller was part of it, but this product was also key. (Trying to improve my reviews by being more specific...so do click the ''helpful'' button if you indeed feel it was)

can't tell if there's a diference in my skin. does have an interesting smell
after several uses, i cant determine efficacy. my skin looks the same, i guess if anything, my face looks generally a bit red but it may be because of the wind/winter and not the product there is a smell to it thought, which i assume is the ferulic acid but unsure i'l continue using it as directed but am not sure if i will repurchase nice that this CE+Ferulic Acid goes on clear versus the bigger name brands that are orange in color

Good vit c serum
This stuff definitely brightens up my skin, but then I feel like it gets sick of it. It’s like I can’t use it consistently or my skin gets annoyed. It is definitely not the easiest to apply because it’s liquid, but all the vitamin c serums I’ve used are the same consistency. I really do like the product overall and think it’s a good price.

I use it underneath my sunscreen where it augments it and makes it more potent. Face stings slightly but that means its working. Use only a few drops, 4-5 drops daily and finish within 3 months. You have to maintain this regimen. Lots of dermatologist who blog recommend using vitamin c and e serum. There is one by skinceuticals but thats really expensive. I got to know about timeless serum from a reputed skincare blog the future derm where it was recommended for its benefits.

I think that it's work on protecting my skin against the strong ultraviolet light. I can't stop buying it again.

Compré este producto como uno de los dupes del CE Ferulic. La verdad hasta ahora funciona super, se absorbe muy rapido y la textura es agradable. Le da un brillo muy lindo a la piel. Comparando este producto con otras vitaminas C de precios similares este producto se siente mucho mas premium, y por ahora, siento que si puede ser un buen reemplazo del CE ferulic.

If the serum is not clear in color - do not use it! It is not effective and will cause irritation.
