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?
I am asked this question all the time.. There is a lot of mis-understanding about the differences between lasers and IPLs, and how they interact with the skin. Some people think that lasers are “superior”, but this depends on what you’re targeting! I put together a wee animation (below) to try to explain some of… Continue reading Which is better – laser or IPL hair removal?
How do we choose the ‘best’ filter on an IPL system? I’ve noticed that, recently, some mis-information seems to be pervading IPL-land!! For some reason, users are being advised to use the wrong filters for certain treatments. I’m not really sure why this has happened, but here is my answer to this… Hope this helps,… Continue reading Choosing the appropriate IPL filter
I am planning to run a ‘Masterclass’, or two, later this year, in the UK. Watch the following video for some details… Please write to me at MikeMurphyLPA@gmail.com to register your interest. Thanks, Mike.
The carbon facial treatment was originally developed in South Korea in the early 2000s. It is now becoming more popular across Europe and America, and various other countries. More recently, this process has been applied to the backs of hands, and other areas of the skin, such as the décolletage. It is claimed that this… Continue reading Carbon Facial treatment with the QS Nd:YAG laser

I presented a video to the British Medical Laser Association conference in May 2021, discussing my work on the physical processes which may be occurring during laser tattoo removal. In it, I discuss the formation of steam bubbles, how they evolve over time, the latent heat energy of vaporisation and condensation, and the cyclic bubble… Continue reading The physical processes behind laser tattoo removal – what is really going on?
I’ve just made a couple of little animations looking at the differences between the laser wavelengths we use for tattoo removal and how anisotropy comes into play. You might be surprised at what actually happens in the skin. Anisotropy is rarely discussed in the laser tattoo world, yet it has significant effects on treatment outcomes.… Continue reading Laser Tattoo Removal – wavelengths and anisotropy
