Best Anti-aging Device of 2012
Truth In Aging Ultra Renew
There are three reasons why I love Ultra Renew. First and foremost, I find the device especially effective in ultrasonic mode for firming the skin, particularly the jowls and jawline. Secondly, there are three LED lights (red, blue and green) that are integrated for convenience (no changing of panels necessary). Third, it takes less than 15 minutes (typically I use it for 10 minutes or less), three to five times a week to get results.
Although these technologies, scaled back for home use, are fairly new, there is robust science behind them. For example, in October 2008, German researchers identified how LED works – by changing the molecular structure of a glue-like layer of water on elastin, the protein that provides elasticity in skin, blood vessels, heart and other body structures. The light strips away those water molecules that are involved in the immobilization of elastin, gradually restoring its elastic function.
There are theories that the non-thermal actions of ultrasound are also important and beneficial. The idea is that the rapid oscillation of tissue created by ultrasound energy promotes movement of fluid waves against cells, facilitating movement between the inner and outer cells and thereby increased fibroblastic activity and collagen formation.
One feature that I was personally a little skeptical about – the theory that ultrasonic increases product penetration – actually seems to be proven. One study I found demonstrated enhanced penetration with a vitamin C serum used for hyperpigmentation. It seems to do this by a process called cavitation – the ultrasound creates bubbles that implode to produce millions of microscopic jets of liquid (your serum in this case).
