I've run across this too, but as with all of these skin care products promising younger skin, you never know what and what isn't a scam.
These Xtend-Life products allegedly use two "special" ingredients which, if the claims are really true, would logically lead to skin qualities of younger skin.
These two ingredients are:
1. Phytessence Wakame - This is a type of seaweed. They say it is a hyaluronidase inhibitor. The following is a quote from the ezinearticles website: "Hyaluronidase is an enzyme that breaks down hyaluronic acid in our skin. And hyaluronic acid is very important to our skin. The effect of hyaluronic acid, when combined with elastin and collagen, is to maintain the smoothness and elasticity of your skin right into old age. It keeps your skin toned and looking youthful. It makes sure that your skin not only looks youthful, but is healthy too." True or not, I have no idea. It'd be nice if there were some actual clinical trials with real data to reference...
2. Cynergy TK - This stuff allegedly stimulates regrowth of both elastin and collagen. They claim there was a clinical trial on this one in which elasticity increased by 42% in 18 days. I don't know exactly what this means in terms of improved skin appearance, and they show no before and after facial photos. Furthermore, the clinical trial info is second hand, as I haven't been able to find the source data on any website.
In a nutshell, I can't determine if this stuff is for real or not.
If the claims of the ingredients hold true, then I can definitely see the logic in having an improved rate of production of collagen, elastin, and HA (hyaluronic acid) lead to younger looking skin (assuming these are truly the major components of skin appearance).
Again, I don't know if this stuff is for real or just another scam to take our money. It'd be nice to see some before and after photos, so if anyone wants to try products with these ingredients, please share with us the detailed results.
