Rated 1 out of 5 by from Very disappointed - flaking mess I was so excited to receive my order, looking forward to active products as I have enjoyed the fabulous DDG peel for years. Unfortunately, in my opinion, this serum should not have been released as it is. It leaves behind a flaking mess which you must continuously wipe off throughout the day. It is worse when you try to put on makeup over it, so I went to using at night. I would rather use my vitamin C serum in the am. In addition, I noticed no brightening and smoothing as I have with other companies Vitamin C serum. When I called to get a refund 2 1/2 months later, they explained that refunds were only within 14 days. I am in the military and very busy, and travel for work extensively. I did not have time to attend to that within 14 days. I feel quality companies should stand behind their products, and the very short return window really makes me suspicious. Most places have at least a 90 day return window. Will not be reordering from them at all.

Rated 4 out of 5 by from Fantastic product! Does an excellent job of brightening and firming; you see the difference the next morning (I use this at night along with the C+ Moisturizer). I took one star off, however, for this reason: it gives a brownish/orange tinge to the skin. I'm extremely pale (Casper the Ghost pale) and it's obvious as soon as it dries. This causes my makeup to look "dirty" as it does darken it to the point of being obvious against my neck. No way I can use this during the day. Other products of his don't do this so....just be aware. : )

Rated 4 out of 5 by from It works! I am a devotee of the ferulic acid and retinol serum and peel and also the hyaluronic serum. I received a deluxe sample of the C serum and lotion and piled in. At first, I didn't like it. It sits on top of my skin and pills. It's also not hydrating for me. However, I stuck with it for a week just using it at night and finishing it off with marula oil for hydration. In 7 days, there was a noticable (I mean really obvious) fading of age spot on my cheeks and my chest looks 10 years younger from an overall fading of sun damage. I'm 48 with medium light skin color, not sensitive, tending to dry side. I will reorder this set full size for intensive use this winter. It's not the most pleasant experience to use it due to the texture once dry and smell, but the results are wicked good.

Rated 5 out of 5 by from Brighter skin My skin has always been patchy with redness and uneven tones (and I'm in my late 20s). I use this every night after I take my makeup off and I have seen great improvement in the tone and brightness of my skin! I will continue using this- it's perfect!

Rated 5 out of 5 by from The best hands down!!! I’ve been using this serum for about 2 months now and my skin isn’t completely transformed!!! Definitely notice my skin is a lot brighter and my acne scars (from picking as a teen cuz I just couldn’t help it) have lightened tremendously!! Seriously can’t say enough!! Don’t hesitate to buy this— take the leap and you’ll see for yourself! I use this every night after microneedling (to help my serums sink in deeper).. dreaming for owning more products from this amazing line!! Dr Dennis Gross for life!!

Rated 5 out of 5 by from Fast-acting, easy to layer, clarifying, toning - has become a routine staple! I use this over the Ferulic + Retinol Brightening Solution. I had been using the Brightening Solution for a long time before I bought then started to layer the C + Collagen Brighten + Firm Vitamin C Serum on top of it. I let the solution absorb completely (doesn’t take too long) before layering the Vitamin C Serum...the combo is a really great fast-acting and effective routine! When used alone, each formula is a standout for next morning results but together I just love it. What I see in the morning (I use them together before bed although you could do morning and night or just morning...), is skin that is hydrated without being shiny, my skin has a porcelain effect to it...evenly toned, brighter just as the product names suggest but a brightness that is from within, not as in light reflecting off me and I am shiny bright. A beautiful clear/bright if that makes sense. The kind of smooth and bright complexion you don’t want to ruin with too much make-up. Other products layer well on top of this during my routine after I pat it in and let it dry. In the morning, I do an uncomplicated rinse cleanse and daytime products absorb beautifully as well. I would love to see this in a larger sized bottle that could last longer....because I also pat what I can onto the tops of my hands and wrists at night and it makes a difference there as well where I have started to see some spots appear. They have diminished or at least not gotten worse since I started to pat the product there with what’s left after patting into my face from 2 pumps...so a product I intend to keep in my regimen for consistent, quick, dependable and very satisfying results. Most of my performance skincare products are Dr. Gross products and I gift my favorites to my mom and sister every year because they love them as well. Thank you for making a product that works, giving it a name that clearly states what it is and should do, putting in a bottle that keeps it stable, and especially for being cruelty free...if it wasn’t, I don’t care how good it is...I would not consider a product that is not cruelty free. And all of yours are cruelty free! Dr. Gross, you truly think things through - you are the real deal!

Rated 5 out of 5 by from Lighten post acne marks I've only been using this baby for less than 2 weeks, and I kid you not... The acne marks have already begun to vanish! I don't know what this does for fine lines, as I've only used it for a short amount of time. I gave this a 5 star because I'm blown away at how fast it works. The smell does come off as weird, but it disappears as it sinks into the skin. Doesn't have a weird oily or a film-like residue. I top it off with either an oil of my choice or a moisturiser. Will definitely buy more :)

Rated 2 out of 5 by from Unpleasant smell I love Dr Dennis Gross products and thought I would try this newer serum. It smells like vinegar so it takes a like bit to get past the smell when applying. I’m also not crazy about the sticky feel it leaves on my skin.

Rated 4 out of 5 by from Awesome serum I have only been using this for about three weeks but am starting to see brightening of my sun spots and overall complexion. I am very sensitive to vitamin c serums and have had no problem with this one.

Rated 5 out of 5 by from Most beautiful serum in the world! I bought this about 6 weeks ago and WOW! Even though i didn't think i had very uneven skin tone or anything like that, this has just made my skin look so bright and it actually looks so clear with no bumps or anything! Its almost as if its porcelain Its crazy! It has the most insane ingredients and also smells divine to which is a bonus! Cant wait to buy it again and recommend it to everyone i know

Rated 5 out of 5 by from Loving this already I purchased this not long ago and am already loving it. My skin feels so smooth and I can feel it working. It’s sticky for a little bit once you’ve smoothed the product over your face, but quickly disappeares after I’ve used their moisturiser (which I’m also loving). Love that these products are clinically tested and produced. Will certainly be looking at more of Dr Dennis products in the future!

Rated 5 out of 5 by from Immediate Results! I started using this product a few weeks ago . Immediately that my skin felt and looked better; the texture, the firmess and fine lines appear smoother. I highly recommend this product! I prefer to use it after cleaning my face, then using the Alpha Beta Extra Strength pads and then apply the C= Collagen Brighten and Firm Vitamin C Serum My skin has never looked better!
Date published: 2017-01-04
Rated 5 out of 5 by from Great value I have used this product for 2 months, each morning , gently massaging it into my skin -along with use of the Alpha Beta peels, I have noticed that my skin looks smoother and complexion more even in tone. And despite the cold temperatures, my skin did seem overly dry. Great way to start my day. And unlike some other serums, there is very little smell to this product.

Rated 5 out of 5 by from Shine bright like a diamond I got this as a gift a month ago from a friend who is a pharmacist and a beauty blogger.

Rated 5 out of 5 by from Love love love!! My skin tone is so much better and the texture feels amazing. I use this at night after I do my nightly reginmine and it's made my skin so much nicer. I have combination skin and it doesn't dry my skin out or make it oily. When I wake up in the morning it's like I have a new face! Will continue buying after I use it all and would love to try other products!!!

Rated 5 out of 5 by from Brighter complexion I bought the serum one month ago in addition to the peels and boy has my complexion improved. The peels are helping the hyperpigmentation decrease and this serum is speeding up the process in addition to helping my pore size decrease and give my skin a healthy glow, will definitely be repurchasing.
Date published: 2017-02-25
Rated 5 out of 5 by from Results!!! I bought this item about 2 months ago. I was using a different moisturizing vitamin c serum. This one is so much better. Love that it is stabilized vitamin c and proven results, along with other great benefits. Will be repurchasing. Also love that it doesn't break me out!

Rated 5 out of 5 by from Wonderful addition to my routine I just recently bought this but can already tell a difference in my skin tone and texture! I use it in conjunction with the daily alphabeta peel! My skin already seems brighter! Will keep this in my rotation and looking at the other products in the line!
Date published: 2018-01-26
Rated 5 out of 5 by from Every Day! I use this every single morning before I put on my makeup. It is fast absorbing and doesn’t leave me oily or give me a break out. I wear loose powder, so anything heavy or oily makes my powder go on too thick, and I’ve found this is perfect.

Rated 4 out of 5 by from ENHANCES MY FACE My skin care specialist suggested this product to be included in my Dr. Dennis Gross Skin Care regime. What I have appreciated about the product is the subtle yet noticeable positive changes in my skin.

Rated 5 out of 5 by from LOVE LOVE LOVE I started off with one little box of facial wipes. I was so impressed I bought the Vitamin C Serum ... and then the Firming Peptide Milk. Another box of (stronger) facial wipes. Yes, I'm hooked!

Rated 5 out of 5 by from Amazing Daily Serum So happy I added this to my daily skincare regimen! Brightens, tightens, and smooths. A good Vitamin C serum is a little pricey, but so necessary! A little goes a long way, so it does last.

Rated 5 out of 5 by from Amazing poduct I got to try it a week back... and the feeling with it was awesome... the change after one application was very noticable.. i have combination skin and nothing works on my skin.
