German boffins have come up with a theory that ‘high intensity’ light from LED lamps could be as effective as Botox therapy in removing facial wrinkles. Apparently the light does this by removing the moisture on sub-surface tissue thereby restoring its elasticity. Here’s the actual report for those who’re interested. That sound you hear?

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.
