I started in medical laser clinical research in 1986 as part of my Ph.D. studies in the Bioengineering Unit, Strathclyde University and in Canniesburn Plastic Surgery and Burns Unit. After gaining my degree in Physics and Astronomy from Glasgow University in 1984, I decided not to get a ‘proper job’ for a few more years,… Continue reading My history in lasers and IPLs and other stuff…
I found an old promo video which we made back in 1991 when we launched the world’s first Q-switched ruby laser for tattoo removal. This came after ten years’ clinical research in Canniesburn Plastic Surgery and Burns Unit, Glasgow and Strathclyde University, Glasgow. We launched the DLR-1 Ruby Laser at an ASLMS meeting in San… Continue reading The world’s first promo video for a Q-switched tattoo removal laser
I’ve just launched a new training web site at DermaLaseTraining.com. It includes all the courses I can deliver plus a new shop where I will be selling some items which you may find useful. If you think I should include anything else in this new site please let me know. Likewise, if you find any… Continue reading New training web site
Laser/IPL hair removal has been around since the dinosaurs…. Yet, it is still poorly understood and even more poorly delivered! We have read all sorts of nonsense about this topic on the internet. There appears to be a lot of ‘mythconceptions’ out there, which just keep doing the rounds. So, let’s drill down on this.… Continue reading Why do so many laser/IPL hair removal treatments fail?
We have written a ‘Brief Guide’ to the terms and expression typically used in laser/IPL treatments in our ‘sister’ blog over at ‘The Laser-IPL Guys’ page. Click here to see this post. Ciao for now, Mike.
My Letter describing back-scattered laser radiation from the skin has been published in the ‘open market’ by Springer! I’m very pleased that they have done this. However, I am now thinking that the levels of back-scattered light are higher than I first thought. The is coming from new work I have been doing looking at… Continue reading Back-scattered light from the skin is much more than we think…
Let’s take a ride on a photon. Imagine we can sit on a photon. What would a trip into the skin be like? Well, it might be something like this…. As we leave the laser we will be travelling at nearly the speed of light – that is 30 million kilometres per second! However, as… Continue reading What is it like to ‘sit’ on a photon and be fired into the skin?
Why not try our quiz and test your knowledge? Click here for the quiz. All the answers will be in our new book which should released before the end of September… In the meantime, good luck. Ciao, Mike.
The ‘standard’ definition of penetration depth in skin only considers the incident wavelength and optical properties of the skin. While this may be useful from a physics perspective, it is not particularly useful when considering clinical treatments. A more useful definition must include wavelength, anisotropy, spot diameter and incident fluence. All of these have an… Continue reading Laser-IPL Penetration Depth – a more useful definition
The following is an experiment I carried out to test a theory. A number of experiences had made me think that the time between laser sessions is more important than first thought. My clinical group first developed scar-free laser tattoo removal back in the 1980s in Canniesburn Hospital, Glasgow, Scotland. Back then, we were using… Continue reading Tattoo removed in just 4 sessions using a QS Nd:YAG at 1064nm
