Picosecond vs Nanosecond Laser Tattoo Removal: which is better?

I recently read an excellent article entitled “Effects of picosecond laser on the multi-colored tattoo removal using Hartley guinea pig: A preliminary study” by some researchers in South Korea. You can obtain a copy here – https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6126847/ In it, they compare the use of two picosecond lasers and a nanosecond Nd:YAG laser. In all, they… Continue reading Picosecond vs Nanosecond Laser Tattoo Removal: which is better?

My first published paper…. on laser tattoo removal, in 1990

‘Q-switched ruby laser treatment of tattoos: a 9 year experience’ – British Journal of Plastic Surgery (1990), 43, 663-669.‘ I can’t believe we wrote this paper 30 years ago!!!   I am still working on this topic. In particular, I am modeling the interactions between laser energy and tattoo ink particles, with both nano- and… Continue reading My first published paper…. on laser tattoo removal, in 1990

One-to-one online training now available

  Finally, I’ve caught up with Zoom! I can now offer my training courses online in a one-to-one situation. You can ask me questions during the course whenever you like. Plus, you don’t need to have Zoom on your computer!! I prefer to do these courses with a small group of people – no more… Continue reading One-to-one online training now available

New paper – my musings on back-scattered laser light from tattoo treatments

New Paper – click here I just had a new paper published in the journal ‘Lasers in Medical Science’. It discusses the amount of back-scatter light emanating from the skin during laser treatments. It is much higher than we had previously thought. This comes from new Monte Carlo modeling which found that back-scattering is much… Continue reading New paper – my musings on back-scattered laser light from tattoo treatments

Laser energy, energy density, fluence, leprechauns and star bursts……

  I constantly hear laser users talking about the ‘energy’ they are using to treat tattoos, hair, blood vessels etc. However, it is clear that many don’t really understand what they mean. I often read about treatments using “500” or “250” or “never above 600” joules, millijoules or whatever!! I think these are the numbers… Continue reading Laser energy, energy density, fluence, leprechauns and star bursts……
