I use to be a big believer in the CE Ferulic and used it for many years… On a whim I tried this serum since I already use a few of their other products. From my standpoint, the pros.. its in an airless pump so it will not oxidize, no fragrance / smell, goes on very smoothly. I gave it a full 3 months of consistent use and I have to say the results were amazing! For me this works just as well as the CE or maybe better. You dont have that meat smell and the oxidation of the product. Also, this is ...

I have tried several other medical-grade Vitamin C serums but this one is superior; at least for my skin type. It does not cause me to breakout, or have sensitivity like the others. This one seems almost hydrating and makes my skin so smooth and radiant! I am 42 years old. I have oily acne-prone skin, but with the right skincare its very manageable! I also have done some SkinPen microneedling which helps too. I will not be without this C!!

Ive been using quite a few skincare products and really like the way the products perform together. I have been using the C-RADICAL serum for a couple of weeks now and can see a difference in the texture of my skin already. Its considerably smoother and firmer. I also like that this serum doesnt burn or irritate my skin like other brands Ive used before. I highly recommend this C serum.
Linda
I wanted to try this product so I bought the small size. However, I was unclear whether to use it before or after Restorative Serum or instead of it. What order should these products be applied? I sent a message to their Contact Us section but I heard nothing back from them. So I am at a loss on how to use this product. I think it may work well to brighten my skin but I wont purchase it again if I dont know how to use. I dont like just throwing money at things without knowing why.

Ive used many Vitamin C serums over the years. Most were medical grade and highly rated. Most also caused irritation, burning, even peeling, no matter how careful my application. This serum does NOT irritate; applies easily; absorbs quickly; and does not cause pilling of products applied after. I have only been using it for about 3 weeks so I cannot yet speak to all of the benefits attributed to this product. One benefit that stands out is how quickly it has evened out my complexion; and the ove...

Im always eager to try new products from this brand since their products are top-notch. So when I read about C-RADICAL Defense Antioxidant Serum I just had to give it a try. Good decision. This serum makes my skin soooo smooth and glowing. I like it so much that after using it for several weeks, I ordered another bottle to have on hand so I wont run out of it. My plan: when I finish a bottle, I will automatically order another bottle so I always have one on hand.
Judy
Im using an assortment of products, all of which I have had great success! For the last month I have been putting on this serum morning and night. I’ve been wanting to try it but didn’t because I thought it might be overkill. However, I have seen a huge difference in the texture and brightness of my face! I love all the serums but this one really improved my skin FAST!!! It saves me from using a lot more expensive serums. I have had so many compliments on my face and neck since using these skinc...
Shelley
I have rosacea and I am always hesitant to switch products. I had been using the gold standard vitamin C serum for years. But I use most of this skincare line, so I decided to try their C serum. It isnt tacky and goes on smoothly. My face is instantly calmed and I wake up with plump, hydrated porcelain skin! It really eliminates the redness! I highly recommend this product for anyone with sensitive skin. Its non-irritating and non-drying. All of the benefits of Vitamin C without the side effects...
Kathryn
Gentle for sensitive skin! This is the first Vitamin C I have tried so far that has not upset my sensitive skin. Its a pleasant texture that layers well with other serums and both gel and cream moisturizers. I cant wait to see the long-term results as its the only Vitamin C I have been able to use consistently. Impressed so far.
Meryle
This is a very pleasant and light gel serum with no fragrance. It is not sticky but does leave my skin feeling smooth and primed. The dispenser has a twist-up cap which I like very much for keeping oxygen out of the product for as long as possible. Some of the ingredients seem very interesting. The product itself is immediately hydrating but further results will require longer-term usage to identify.
Crystal
I have struggled with melasma for the past 15 years. Im always looking for the newest and best products to help with pigmentation. I tried the Brightening Serum and was pleased with the results, so I decided to give the Vitamin C serum a try. I like the serum; however, Im not seeing the difference in my skin that I see with other Vitamin C serums.
Nancy
Ive been using the C-Radical serum for 2 weeks now and already notice improvements to my skins brightness and clarity. My skins coloring is more uniform without blotchiness. It goes on so smooth and absorbs quickly. Overall my skins texture and clarity are noticeably improved.
Elizabeth
This is far and away the best Vitamin C serum Ive ever used. It feels wonderful on my skin, not oily at all, and it doesnt sting. Ive used this since it came out and my skin tone is more even and less red. Ill be 70 next month, and thanks to these products and daily sunscreen use, I look at least 25 years younger.
Carolyn
This is one of the ONLY C serums I can use. I have extremely sensitive skin and its quite the endeavor to find facial care products that do not turn my face into a giant rashy cherry tomato. I love this C serum and will continue to purchase!
Victoria
I really wanted to be able to incorporate this into my skin routine to replace another Vitamin C serum I used but it caused a lot of redness and irritation to my face when I used it. Unfortunately, it was past the 30-day return window. I really love their other products, but this just didnt work well for me.
Raquel
Great for sensitive skin! No redness at all! I really recommend it! It looks like a heavy cream, but it isnt at all. Your skin absorbs it very quickly, and you feel instantaneously the difference when you touch your face.
Brooke
I have been using this product for about a month and seeing that my skin is noticeably brighter and smoother. I have also experienced fewer breakouts. I have combination skin and I feel like Im more hydrated and glowy. The product goes on very smooth and absorbs quickly so that I can layer my next products.
Lisa
I added this product to my normal daily regime. I felt a positive improvement immediately after applying it for the first time and it only took two days to see a real improvement in my skin. My skin feels smoother and softer and my lines are lighter already! I am obsessed with this product. Its a must-have.
Mary
I have worked in an OR for many years. Wearing a mask for long periods of time often dries out your skin. I keep this product in my locker and apply it several times during my 12-hour shifts. My skin always appears supple and the lines are hardly noticeable.
Amy
This is the best C serum Ive ever used. I love the whole line and my skin looks great since Ive been using the products. One pump is all thats needed. Soaks right in and no sticky feeling afterward.
Kym
Ive only just started this product a week ago so I dont yet know the long-term effects. However, my tired and stressed skin at least FEELS better. Im a Vitamin C junkie so Im hoping to reap more benefits soon. Love the texture and sinks right into my skin.
Lisa
I noticed within a week of using this product, my skin was smoother and brighter. The redness in my cheeks went away and fine lines appear smoother. So excited to see what happens after using it longer. This will be a definite repurchase!!
Rachael
I havent tried everything from this brand, but hope to try more. Each product I have tried has been a solid choice that I would or would consider purchasing again. With the antioxidant serum I liked the texture and ease of application.
Roberta
I use it after toner and before my moisturizer. Its a very nice texture and the skin absorbs it quite well. You feel plumped and glowy. Im very pleased with this product.
Lindsay
I think its too early to tell as Ive only been using it for a week. However I do like the airless pump bottle which ensures the vitamin C isnt exposed to oxygen. The product goes on seamlessly and doesnt leave a sticky or tacky feeling like other vitamin Cs Ive tried in the past.
Mindi
This C-RADICAL Defense Antioxidant Serum provides visible results. My skin is noticeably brighter and seems smoother. It goes on smooth and absorbs quickly.
Mary
Ive been using a combination of Restorative Skin Complex, A-luminate, and C-Radical Defense for the past couple of weeks, and this is the best my skin has looked since my 20s. My overall skin complexion, texture, and brightness is so apparent. Im confident to go out without makeup on now.
Karina
Ive been using C-RADICAL Defense Antioxidant Serum for about two weeks and seeing that my skin is noticeably smoother and softer. Also, I like the lightweight and quick absorption formula. I cannot wait to see other improvements in my skin.
Rosemary
I love these products, all I have tried are amazing, hands down. This is my favorite serum. I have been using it for a couple of weeks and have noticed a significant improvement in my skin. Thank you, 5 stars!
Stefanie
So far I love the way this product goes on my skin, absorbs well and fits right into my skincare routine. I like the formulation and hope to see long-term results. My skin does look brighter!
Mochi
After using it every morning and evening, I dont have a sting or sticky feeling, but feel normal comfort. My skin looks brighter and glows. Ive only been using it for a short time but already notice improvement.
Eva
The serum leaves my skin smooth and glowing—looks like Id had a facial. I use it with other products. A little goes a long way—2x/day—usually close to 2 months.
Ingrid
Ive tried so many Vitamin C products and this is the first one where Ive visibly noticed a difference! I have it on a subscription now so I never run out. Perfect packaging and incredible product.
Sarah
Hadnt tried a Vitamin C serum before. My 40-something skin was needing a boost and a friend recommended I add Vitamin C to my regimen. I love it. My skin looks brighter and firmer. Seems to be helping hydrate my skin as well. Highly recommend.
Krista
I havent used the product long enough to see a noticeable difference in dark spots. The serum has a nice smell and blends in easily. It doesnt cause my makeup to pill when I wear it over the serum.
Josephine
I enjoy using this product daily as part of my skincare process. Noticed a difference in my fine lines after 2 weeks of use and it really helps refine my skin tone. Definitely recommend it.
Treva
I have tried numerous products on the market and through my dermatologist. At my age, serums are a must. I love all these products and especially the C-Radical serum!
