You got to be kidding me??? One of my LPA client’s recently had a laser break down during treatment. He stopped treatment immediately and checked the system. It came back with an error code – which was meaningless! So he called me out to have a look at it. The main unit appears… Continue reading Unscrupulous laser suppliers!! Beware…
What is this ‘Level 4’, ‘Level 5’ in aesthetics stuff all about?
Like most people I was a bit confused about this new ‘Level 4’, 5, 6 and 7 malarkey! I hear conflicting information from various sources saying that everyone using lasers/IPLs “must” be educated to these levels; then other sources saying “not yet”!! So, what’s the state of play? I recently came across an… Continue reading What is this ‘Level 4’, ‘Level 5’ in aesthetics stuff all about?
Do you need gel for photothermal treatments?
Water-based gel is routinely used when applying lasers and IPLs on skin conditions like vascular lesions, benign pigmented lesions and hair removal. However, some manufactueres and suppliers suggest that gel is not required. Im not really sure why! So, what happens if you use, or don’t use, gel? As far as I am concerned… Continue reading Do you need gel for photothermal treatments?
James Clerk Maxwell – a genius
James Clerk Maxwell was a Scottish mathematician and physicist who derived four laws which became the basis of electromagnetic theory. He discovered that all electromagnetic radiation moves at the speed of light, c, in free space. Einstein based his theories of relatvivity on Maxwell’s work and cited him as a genius. Sadly, he… Continue reading James Clerk Maxwell – a genius
Picosecond Lasers???
Are picosecond lasers as good as they claim? Tattoos can be removed by either nanosecond or picosecond lasers. Nanosecond lasers have been used for this purpose since the early 1980s when my group first successfully demonstrated the scar-free clearance of black tattoo ink using a Q-switched ruby laser in Canniesburn Hospital, Glasgow. (Reid W.H.,… Continue reading Picosecond Lasers???

Flying fragments
A couple of years ago I noticed pits on my glass slides after laser tattoo treatments. Under a microscope I could see ‘craters’ which had been formed by high speed ink fragments flying out of the skin. But I also saw what I call ‘insects’: I think these are melted portions of ink… Continue reading Flying fragments

How long does it take a new photon to reach us from its creation in the sun?
All of the sun’s photons are generated through nuclear reactions within it. If a photon is generated at the centre of the sun it can take anywhere between 2 days and 200,000 years to escape the body of the sun. That’s because the path of the photon is purely probabilisitic. At the centre of the… Continue reading How long does it take a new photon to reach us from its creation in the sun?
How fast is the Earth moving through space?
Ever wondered just how fast we are moving through space? Well, the Earth revolves around the Sun at around 30 km/sec, in its annual path, which takes a year to complete. The Solar System revolves around the Milky Way centre at around 230 km/sec. It takes around 225 million years to complete… Continue reading How fast is the Earth moving through space?
