Cellex-C Advanced C Serum

One star isn't for the product, it's for the Skin Store

My dermatologist recommend this C. I wish it wasn’t so expensive but it’s really good.

I have used Cellex-C C Serum for over 25 years. Have tried other brands, but always go back to the Cellex-C. I'm a senior citizen and have smooth skin, with few wrinkles for my age. Ladies and gentlemen take care of your skin!

This is a great product and really improves skin texture and tone. What is outstanding with this company is that they fill the pipettes with product within the bottle, giving the customer more product for the money. That kind of attention to detail is impressive.

I have used Cellex-C for many years. It is the first company to come have come out with a C serum. Never had any reactions, and I do believe it has helped my skin to be younger looking. I have tried others that seem to be more popular, but they cannot compare to this. And my skin looks better then girls 20 years younger than me!

i am a 39 yo women from israel.i have semi-oily skin.i have tried all vit-c serums. i tried skinceuticals,skinmedica,obagi (also the Rx line),IS Cinical,PTR, Etc..you name it,i tried it!The Only one i miss and go back to is thIs serum by Cellex-c!i just Love It! - i try others, but then always come back to this one because of the super glowing radiant skin it gives me.listin.....dont expect "Miricales".a good vit-c serum is only ONE "superstar" ingredient in the battle against aging skin.it is only one of a few crucial "bombs" that fight against aging.but it is an important one and NOT all vit-c serum are equals (and no...percentage of L-ascorbic is NOT what makes a vit-c serum more powerfull).in order for a vit-c serum to do work its magic.....it needs to have (first and foremost) a SUPERB "delivery mechanism".that delivery system will take the l-ascorbic acid Deep into the skin....and that is exactly why i think CELLEX-C is Superior to all others.they are a Pioneer in Vit-C Skin Care and i Can definitely feel the deference!you see ,in the past, the Cellex-C formulations were concidered superior antioxidant serums compared with those of Skinceuticals (for example) because they contained more diverse antioxidant combinations, however both companys now feature "broad-spectrum" antioxidants.Skinceuticals claim their most photoprotective antioxidants are "CE Ferulic" and Phloretin CF (i tried the CE Ferulic,it was nice,but not "Great").Cellex-C claims that their superior antioxidant is this Advanced-C Serum.Further complicating matters, IS Clinical claims that their "Super Serum Advance+" is superior, and Obagi says that even one of their 10% Vitamin C serums(tried it...really nice and better then skinceuticals) readily outperforms Skinceuticals 20% vit-c serum.Cellex-C uses tyrosine, zinc and bioflavonoids in their Vitamin C Serums whereas no Skinceuticals Serums contain tyrosine and only some contain zinc.(BTW: The use of tyrosine is protected by a Cellex-C patent).Medical literature states that when tyrosine is combined with ascorbic acid (vit-c) it helps to promote regeneration of new connective tissue through the stimulation of fibroblasts enabling them to create more collagen.while a A study that was co-authored by Skinceuticals cheif medical director Dr. Sheldon Pinnell (Rest his soul in peace) holds that zinc is an important and neglected antioxidant for skin.Zinc has been shown to help support increased collagen turnover stimulated by ascorbic acid it is an essential component of collagenase, which is required to dismantle old, defective and stiffened collagen in order for new collagen to be constructed.so If more types of antioxidants are better than less, it could be that Cellex-C Advanced C Serum is the most optimal antioxidant (because it contains five diverse antioxidants (l-ascorbic acid, zinc, resveratrol, pycnogenol and L-ergothioneine) and also contains tyrosine, as opposed to Skinceuticals "CE Ferulic" which contains three antioxidants (ascorbic acid, ferulic acid and Vitamin E) without tyrosine or zinc.however Skinceuticals "CE Ferulic" has been shown to provide a remarkable 8x endogenous photoprotection (no studies into the photoprotection offered by Cellex-C Vitamin C Serums have been published).There are many grounds on which to consider whos "the best" and I do not believe you will ever find a brand which is "best" on all fields.just do your own comparative study by using Cellex-C Advanced-C Serum for at least 4 months and then switching to Skinceuticals CE Ferulic for another 4 months.from My personal impression?the "CE Ferulic" was a whole lot less firming and powerfull compared to the Cellex-C "Advanced-C Serum".i truly believe that as a vit-c serum....the cellex-c is Far Superior to all others (i have tried).but like i said....its Only One superstar of a few that combat aging and wrinkiled skin.remember to use it in conjunction with a few other superpowers:1- Retinoids! (Rx Tretinoin or over the counter retinol based creams).2- L-ascorbic acid serum (vit-c serums of your choice).3- Glycolic acid products (Chemical Exfoliating products from the AHA groups).4- and try to use one Top notch ultra advanced New-Age product which contains lots of peptides and grouth factors.5- **Sunscreen** (most important **Prevention** step).use all five crucial superstars and you are fighting aging (topically) in the best way you can (in this current day and age).i did them ALL...i did the Whooole trip from high-end ultra "lux" brands (such as La-prairie,La-mer,Natura Bisse,Revive,cle de peau) and all the way "down" to the "Physician Strength" brands (Skinmedica,Skinceuticals,Obagi-Nu Derm program,IS Clinical,MD Forte,Vivite...Gosh im sure i forgot some! lol).today.....i stay away from "lux" brands (except for makeup and stuff).my regimenMorning.......cleanse with Obagi "gentle cleanser" and wipe face dry.PTR "un-wrinkle peel pads" (wipe on dry face,leave on 2-3 min,rinse with water).La prairie facial mineral exfoliator (on damp skin right after washing of the PTR).Tone with Obagi tonerthen i use in this order (but wait 2-3 min after each product to let sink in).Cellex-c advance C serum (4-5 drops).Skinmedica TNS Essential Serum (A-M-A-Z-I-N-G).Md Forte Eye cream (sometimes i layer the skinceuticals "eye balm" on top if i feel dry).Obagi Exfoderm forteZo skin oclipse sunscreen (the Best and most AMAZING sunscreen in the world).Evning:cleanse with Obagi "gentle cleanser".Tone with obagiSkinmedica TNS Essential Serum (also under eyes)Tretinoin cream 0.5Skinceuticals "eye balm"and if you want some moisturizer ( i dont) then i suggest you use skinmedica "replenish hydrating cream" or their "dermal repair" or even a good basic moisturizng cream like the Cerave "pm moisturizer".*i also Love the Dermalogica "multivitam power recovery masque" for twice a week "pampering" treatment.im not into facial "masks" normally (i find them kindda useless) but i love this mask and i use at as a "pick me up" mask on long night or when i fly and my skin dosent look its best.its a beauty mask for me and its the ONLY one i ever will use and repurchase.Good luck!Sarai from israel :-)

Makes skin smooth and soft and softens fine lines. I would not want to be without it.

I've been a faitful user of Cellex-C for almost 10 years now. I am a huge fan of this product and use it almost daily. The only problem I have found is that the top of the bottle can stick if the serum gets under the dropper top.

I use this serum with Cellex-C Hydra B serum every morning. I have a lot of sun damage, and while this serum didn't get rid of my persistent melasma, it certainly improved my overall skin tone. My skin has never looked better... it's brighter and has a healthy glow! I also love the simple yet potent ingredient list in this natural, paraben-free product. This advanced formula doesn't irritate or dry out my super dry skin. There's nothing to dislike really other than the price tag... however I think this serum is worth every penny!

Best and most effective product I have used for wrinkles. I use hydrating b after before moisturizer.
