I’ve just completed my “Introduction to Laser Safety for lasers and IPLs” in the medical/aesthetic setting, booklet. You can find it here – Laser Safety booklet. It’s a free downloadable 24-page pdf, which discusses the various aspects of laser and IPL safety under current UK and EU regulations. It includes a description of the ‘Core… Continue reading My ‘Introduction to Laser/IPL Safety’ booklet

Paradoxical hair growth – is it?
We often hear about ‘paradoxical hypertrichosis’ – unexpected hair growth – after laser treatments. No one seems to know why this happens. There is very little research on this topic too. So, what is going on? Well, I don’t think it is actually paradoxical hair growth at all. I think that, in many cases, we… Continue reading Paradoxical hair growth – is it?
BMLA talk 2024 – Pre- and post-cooling is important in photo-thermal treatments in improving results and reducing pain and unwanted tissue damage
I have been advocating the use of ice pre-cooling and post-cooling for a few years, with great success. Not only does the ice reduce pain, blistering and pigmentary changes, it also allows for higher fluences to be applied, safely. Higher fluences will always result in better success rates. It’s a ‘win-win’ situation! This talk discusses… Continue reading BMLA talk 2024 – Pre- and post-cooling is important in photo-thermal treatments in improving results and reducing pain and unwanted tissue damage
BMLA talk 2024 – Modelling the heat conduction losses during long pulsewidth laser/IPL treatments
In this talk I discuss my 1-dimensional computer model which looks at the temporal evolution of the heat distribution, during and after irradiation of hair melanin. During longer pulsewidths (> 1ms) heat can ‘escape’ from the absorbing melanin into the surrounding tissues. As a consequence, the temperatures in the melanin are not as great compared… Continue reading BMLA talk 2024 – Modelling the heat conduction losses during long pulsewidth laser/IPL treatments
