How long does tissue take to be damaged by heat?

I often read about human tissue ‘denaturing’ or ‘coagulating’ at some temperature – usually 60 or 70°C. However, these claims are inaccurate. They rarely state the time over which the denaturation process occurs. Denaturation is when the proteins in cells or tissues ‘unravel’. For example, collagen is made up of three amino acid chains, intertwined… Continue reading How long does tissue take to be damaged by heat?

Carbon Facial treatment with a QS Nd:YAG laser

Recently I tried the new ‘carbon facial’ treatment using the 1064nm wavelength of the Q-switched Nd:YAG laser. My wife was keen to try it! I painted a little black carbon ink solution (which I made myself) onto my wife’s face. After about 20 minutes, or so, to allow it to dry, I applied the laser… Continue reading Carbon Facial treatment with a QS Nd:YAG laser

Calibrating your laser – making sense of the numbers…

How do you calibrate your lasers so that the numbers on your laser screen actually mean something useful? Well, there is a process which you need to follow. The video shows this process in detail. So, you need to measure the laser energy for each of your ‘input’ settings using an energy meter designed for… Continue reading Calibrating your laser – making sense of the numbers…
