This is stable C-serum formulationand not as pricey as the other serums Believe me when I say I've tried many others.I've seen faster and better resultswith Cellex than Skinceticals and Obagi C serums. .
this is the only formulation with tyrosine and zinc with vit c--and patented so can not be duplicated. without tyrosine, vit c can not go deep enough to stimulate collagen remarkably. i recommend this wholeheartedly over skinceuticals, obagi and skinmedica etc. the advanced series has hydrolyzed vit c so collagen is produced faster than the original series plus it is choke full of super potent antioxidants. this product erased lines on my face--but be patient it takes at least 4 months to see results. so, while you can get brightening from other vit c out there, nothing plumps and lifts like cellex-c
This stuff is amazing. I've been a user for 5 + years and it has NEVER failed me. Yes, in the beginning, it irritated my skin, but after continual use....my face acclimated. Rosy, luminous, clear, acne free, oil-free, soft and smooth is what describes my face.
My skin has NEVER looked so good. Never. My skin feels and looks better now that I'm 33 than when I was in my early 20's.
Don't forget Hydra B5 and sunscreen.
I bought the Advanced-C serum after using the High Potency which I really liked, because I felt the High Potency exfoliated without making my skin pigmentation worse which alpha hydroxy acids do for my skin. I hoped that the Advance-C serum, having a higher percentage of vitamin C, would benefit my skin even more. However, it irritated my skin too much so I ended up diluting it it with water to use it up. I really don't like the dropper, because I frequently spill the liquid onto the floor or the sink by accident and waste the expensive product.
Quite simply a waste of money. Meant to review awhile ago. Did nothing at all. Don't throw your money away. Stay clear of this product.
Bought this on a whim cause it was on sale after using Skinceuticals C+E ferulic. The Skinceuticals made my broken caps less noticeable and evened out my tone and moisturized and made my wrinkles less deep and this did nothing at all. In fact, I feel that it reversed the progress I had made. Cannot say enough negative things about this serum. Run, don't walk, to buy the C+E Ferulic.
Agree with all the negative reviews here. Waste of money. I honestly tried it for 3 months. NO change in my skin or pigmentation what so ever!
I got a sample of this after a facial. I honestly don't know if it did anything but break me out a little bit, because I could only use it for a few days due to the revolting smell--sort of like a combination of oily hair and self-tanner.
I have a combo mediterranean skin type that I am exposing it very frequently to the sun especially while I am driving. I am 44 years old, choosing cosmetics from all sorts of companies mainly with vast experience in the field. I have read the reviews for the high potency + Hydra B5 kit and I went to purchase it. Unlikely in southen Europe they sell only the professional formulations. So I have purchased The Advanced-C kit consisting of 15ml Advanced C serum and 15ml Skin Hydration Complex. I have used them during the morning for the past 5 weeks but not on their own. After the C serum and the skin hydration serum I use a Guerlain moisturer (Aqua day refreshing gel or Kensoki vital-ice cream) and at the top my sun protection cream SPF 40 of Guerlain or the Cellec-c 30+ ). In that order both Cellex-c serums work fine and I have seen a lot of improvement to my skin texture. Avoid using them all alone without moisturers or with an anti wrikle creams. There is something in the formulas that do not blend well with the wrikle-tightening creams. Price for the kit in my my country is Euro 169!!!. I found it via internet sites ( my second purchase) around Euro100. The difference between the High potency serum and the Advance C serum apart from L-Ascorbic acid consistency 10% vs 17.5% is the Ph. The H.Potency has around Ph 2.5 and Advanced C 4.5 while the skin's PH is 5.
A couple of people said this was great, so I tried it. However, this product (and other products I also tried from this company) really irritated my skin. I did not get any anti-aging benefits, but I broke out like a teenager even though I am in my 50s. Definitely not a line I would ever use again and would not reccomend it.
