ProVectin Plus Advanced Eye Cream Compared to StriVectin
I was pleasantly surprised, on perusing ProVection, to discover matrixyl 3000 (an antioxidant made by combining two peptides) near the top of the ingredients list. This was followed by two more antioxidants, rice bran and soy bean protein. We were off to a very good start.
Hesperidin methyl chalcote is the key active in a product designed to combat dark circles. It is a flavenoid found in citrus fruits and it strengthens capillaries (the idea is that they would then leak less, inhibiting the cause of dark circles). Plus there is a battery of moisturizing ingredients and vitamins.
Unfortunately there are a couple of PEG ingredients. These are polyethylene glycols that are thought to be toxic. Triethanolamine is an irritant and toxic, according to an animal study. There are also several parabens and diazolidinyl urea, an irritant that turns into formaldehyde, and disodium EDTA, which can be toxic (although at higher levels than you would expect to find in cosmetics).
How does it compare to its pricier competitor, StriVectin? Its "Striadril Complex" is made up of matrixyl 3000 and hesperidin plus a couple of botanicals that mostly play an anti-inflammatory role. Overall, the list of botanicals looks fairly impressive. However, with a couple of exceptions - hydrocotyl (helps collagen form), kukui (healing properties) - I couldn't find any references that say what they can do for you.
It has a similar cast of villains (parabens and triethanolamine), with the addition of phenoxyethanol, an irritant that can also damage the central nervous system.
All in all, there isn't enough in StriVectin to justify a price four times higher than ProVectin.
