Is pure light better than Botox? German researchers have formulated a theory that high intensity light from LED lamps could be as effective as the Botulinum toxin in removing facial wrinkles. They say the light removes moisture on sub-surface tissue, restoring it’s elasticity. It would be great if something as simple as light could have these purported restorative effects (as opposed to injecting your face with a toxic substance!)
From the report:
In the study, Andrei P. Sommer and Dan Zhu point out that high-intensity visible light has been used in medicine for more than 40 years to speed healing of wounds. That light actually penetrates into the skin, causing changes in the sub-surface tissue. Until now, however, scientists have not known the physicochemical nature of those changes. They report identifying how the visible light 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.
