I like strivectin. but I can't use it too close to my eyes.
I took another look at the ingredients.. and this does seem to have all the important stuff. and a lot cheaper.
Strivectin was originally marketed as a stretch mark creme, but it was found to be effective for wrinkles.
the clinical trials the stivectin site refers to are these:
Relevance of antiwrinkle treatment of a peptide: 4 months clinical double blind study vs excipient
The palmitoyl pentapeptide palmitoyl-lysine-threonine-threonine-lysine-serine (pal-KTTKS) is a synthetic material that was designed as a topical agent to stimulate collagen production and thus provide a skin anti-wrinkle benefit. To determine if pal-KTTKS is effective, the clinical study reported here was conducted. Caucasian female subjects (n = 93, aged 35–55) participated in a 12-week, double-blind, placebo-controlled, split-face, left–right randomized clinical study assessing two topical products: moisturizer control product vs. the same moisturizer product containing 3 ppm pal-KTTKS. Pal-KTTKS was well tolerated by the skin and provided significant improvement vs. placebo control for reduction in wrinkles/fine lines by both quantitative technical and expert grader image analysis. In self-assessments, subjects also reported significant fine line/wrinkle improvements and noted directional effects for other facial improvement parameters.

I could not find anything on this
however, these clinical trials are about pal-KTTKS which I think is a totally synthetic ingredient. I will have to ask a biochemist I am talking to about this.
I could not find much on the other "proprietary" ingredients.
I am trying to experiment with a vitamin c mix that I can use around my eyes.. but it won't be emollient like the strivectin creme. The strivectin goes on very nicely.
