Throughout the last few years I have heard some people (usually sales people) trying to bamboozle potential customers with various nonsense claims. This is to be expected I suppose, but one which does irritate me greatly is the ‘active’ vs ‘passive’ Q-switch debate!! So, I thought I’d write a wee piece about this topic,… Continue reading Q-switches: Passive vs Active?
Laser tattoo removal has been available commercially since we opened the world’s first private clinic to offer this treatment in Glasgow, Scotland in 1989 following our groundbreaking clinical research program in Canniesburn Hospital, Glasgow during the 1980s (see our 1990 publication in the British Journal of Plastic Surgery). We used the Q-switched ruby laser which… Continue reading Laser Tattoo Removal – the important considerations

I found that there is a significant amount of damage in the capillary plexus soon after irradiation. This… Continue reading “Q-switched 532nm laser energy causes significant vascular damage in the capillary plexus – how does this affect laser tattoo removal?”

QS lasers can output up to 2 Joules of energy in pulsewidths as short as 5 nanoseconds, while some commercially available pico lasers can output up to 1 Joule… Continue reading Are picosecond lasers worth the cost?
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

The cost… Continue reading ‘Lunch & Learn’ – Quick, lunchtime courses in lasers, IPLs, RF and their applications
