Happy New Year to you all. I hope you all have an excellent, prosperous and healthy 2026. We have a number of plans which I’d like to share with you. First, we will be launching our new VTCT Level 5 course for laser tattoo removal. I spent the holiday period writing a new PowerPoint presentation… Continue reading Our plans for 2026

I asked an AI to summarise my books. Here’s what it said…
I asked an AI for a summary of each of my three books.In particular, I asked for the salient points: Three Key Points: Based on the detailed content provided from “An Introduction to Medical/Aesthetic Lasers and IPL Systems” by Michael J. Murphy and Per-Arne Torstensson, here are three core points with their supporting arguments: —… Continue reading I asked an AI to summarise my books. Here’s what it said…
All our podcast episodes to date….
We launched our podcast ‘Lasers in Skin‘ back in Febraury 2025. Since then, we’ve published 41 episodes and had over 13,000 listens – no bad! Onwards and upwards… To let you find an episode easily, I have generated links to the Apple and Spotify platforms: 🔗 Lasers in Skin on Apple Podcasts🔗 Lasers in Skin on Spotify… Continue reading All our podcast episodes to date….
Why we must use HIGHER fluences on darker skins…
When treating skin with lasers/IPLs we are often told that darker skin tones must be treated with lower fluences. This is wrong! Our skin tones come from the concentration of melanin in the epidermis – mostly in the basal layer in lighter tones. In darker skins, the melanosomes may be found throughout the epidermis, not… Continue reading Why we must use HIGHER fluences on darker skins…
Which are the most ‘aggressive’ wavelengths?
Someone recently asked me ‘which is the most aggressive wavelength for the skin?’ That’s interesting question… We should first start by identifying which wavelengths we need to consider. In many skin treatments we use visible and near-infrared light – from around 400 nm up to 1064 nm (Nd:YAG) or even 2940 nm (erbium:YAG). CO2 lasers… Continue reading Which are the most ‘aggressive’ wavelengths?
Fluence, pulsewidths, temperatures and cellular denaturation
This topic is very poorly understood. How does fluence and pulsewidth relate to cellular denaturation – or, ‘cooking’ of the cells. I’m going to portray this in a series of graphs – I hope this works… When we fire light energy into the skin, we can generate some heating, if there is something in there… Continue reading Fluence, pulsewidths, temperatures and cellular denaturation
