Electromagnetic and audio human perceptions of this universe

Human beings are puny things! We really are!! We basically just bags of water with a few extra chemicals thrown in, which waddle about for a few years, then decompose into waste… But, for the time we spend in this universe, how much of it do we actually perceive? Well, it turns out – NOT… Continue reading Electromagnetic and audio human perceptions of this universe

Light penetration into skin and the subsequent temperature rise

Where does light go when it enters the skin? Well, it’s actually quite complicated! Some of it reflects off the skin surface, some is absorbed in the melanin (basal layer), some penetrates through to the fatty tissue, while some is turned around and escapes back into the air. The follow slideshow gives a simple explanation… Continue reading Light penetration into skin and the subsequent temperature rise

My research in pain relief and wound healing

In 2004 I started to research pain relief using sequences of electronic impulses. The technology was developed by an Italian engineer over a 30 year period. He had discovered a way to stimulate responses in tissues by inputting a sequence of electronic impulses while varying their amplitude, frequency and durations. I saw a direct relation… Continue reading My research in pain relief and wound healing

My history in lasers and IPLs and other stuff…

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…

The world’s first promo video for a Q-switched tattoo removal laser

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

Why do so many laser/IPL hair removal treatments fail?

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?

Back-scattered light from the skin is much more than we think…

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…
