Different wavelengths of light penetrate to different depths below the skin surface and are absorbed by different skin or tissue components. For example CO2 and Erbium laser light is absorbed by the water in cells exposed to it. Flahslamp laser light is absorbed by red blood cells. Nd:Yag laser light is absorbed by skin pigment cell melanin and tattoo pigment. Since the eyes contain water, pigment cells, red blood cells etc they can be damaged if exposed to most laser lights either directly or indirectly (from reflected laser light). Even the laser pointers used by lecturers can damage the eye if pointed directly into the eye. Some lasers such as the CO2 have a beam whose wavelength is not visible by the human eye but they can still cause damage to the eye. The CO2 and Erbium will damage the cornea and surface of the eyeball first. Flashlamp and vascular lasers are absorbed by red blood cells and are the most damaging to the eye as they are absorbed by and damage the retina.

What is Botox?
This is a guest post by Sachin from the Cosmos Clinic in Sydney Australia
Botox here, botox there… it seems that all we hear about these days in the cosmetic surgery industry is botox. Hollywood stars use it, New York socialites swear by it… but what is it? If you’re like me, you don’t want to put something in your body if you don’t know what it’s made of. So I did a little research on botox and I want to share my findings with you.
