Hello dear Brains :)
French brand Cudalie is up with the new antioxidant serum which boasts super high concentration of vtamin C and polyphenols.
AQUA (WATER), BUTYLENE GLYCOL, GLYCERIN, SQUALANE, ASCORBYL TETRAISOPALMITATE, TOCOPHEROL, CETEARETH-20, PALMITOYL GRAPE SEED EXTRACT, PARFUM (FRAGRANCE), GLYCERYL STEARATE SE, POTASSIUM SORBATE, ACRYLATES/C10-30 ALKYL ACRYLATE CROSSPOLYMER, CAPRYLYL GLYCOL, XANTHAN GUM, HYALURONIC ACID, CARBOMER, SODIUM PHYTATE, SODIUM HYDROXIDE
In this regard i have 2 sets of questions for you to clarify guys, if you may:
1. Manufacturer states that at the moment these very polyphenols are the most powerful antioxidant on the market. Is that true? Any independant research showing the efficacy of their topical application? What are these polyphenols anyway?
2. Now to vit.C.
I heard that it's quite hard to stabilize in the cosmetics formula, that at the contact with air it oxidizes so fast that can do more harm to our skin than good. Is there any way to say from the list of ingredients that vitamin C in this particular serum is not only stable but also effective when applied to skin?
Thaks a lot for your help and the job you're doing for all of us!
