C + Collagen Brighten + Firm Vitamin C Serum is rated 4.4 out of 5 by 15.
Rated 1 out of 5 by from Drying & Irritating I so wanted to get the benefits by adding the C+ to my regimen. I use and love the results of the DDG Ferulic + Retinol face and eye serums, DDG Triple Peptide Oil, and began using the C+ products during the day, the Retinol at night. Even though I used a good moisturizer or the DDG Triple Peptide Oil over the C+ Serum, after a couple of weeks, my facial skin was not doing well. Skin was drier and fine wrinkles more noticeable. I even experienced random blemishes. This was notable because I never have blemishes. So, my skin did not like this C+ formula. When I went back to using Ferulic+Retinol day and night, my skin got better.

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!

Rated 5 out of 5 by from Best Vitamin C serum, not irritating This is the best Vitamin C serum I've ever used. After 1 week of applying it on my face everyday, a few brown spots have faded and my complexion is even. It does not irritate my skin unlike other Vitamin C serums I've used in the past. The small dark glass pump bottle protects the ingredients from light and air. And it's perfect for travel.

Rated 5 out of 5 by from Awesomeness I've never had people compliment my skin until I started using this. It gives me an even, more tan complexion. And it helps restore a little bit of that youthful glow that I've started missing since I got into my mid thirties. I'm addicted...it's a problem. But one of those healthy addictions so we're good. Thank you, Dr. Gross team!

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.

Rated 5 out of 5 by from It has transformed my skin I bought this after trying out so many vitamin c products on the market but this is so far one of the best. It has completely transformed my skin within days. My skin looks tighter, brighter and rested. Highly recommend this product to anyone looking to improve their skin tone and texture.

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!
