NEW SHORT COURSES I will be starting some ‘Lunch and Learn’ courses very soon. These are designed for clinics/salons where laser/IPL users want to learn about more about certain topics. Each L&L course will last for about 45 to 50 minutes and will be presented via a Powerpoint presentation and a course booklet. The cost… Continue reading ‘Lunch & Learn’ – Quick, lunchtime courses in lasers, IPLs, RF and their applications

Laser Safety Glasses – Are you safe?
All laser users have to take responsibility for their laser safety glasses. Are they the right ones for the job? Are they properly specced? Do they comply with EU regulations? For more on this topic please see my article in Aesthetics –https://aestheticsjournal.com/feature/the-last-word-safety-glasses If you need any advice please feel free to contact me.… Continue reading Laser Safety Glasses – Are you safe?
Thermal Relaxation Time – what is wrong with it?
The theory which has underpinned many skin-laser treatments since 1981 is called ‘Selective Photothermolysis’. It is based on matching the laser wavelength to the absorbing chromophore. It also matches the pulse duration of the laser to the thermal relaxation times of those targets. However, there is a problem with this approach. The thermal relaxation… Continue reading Thermal Relaxation Time – what is wrong with it?
Tissue denaturation – the process
And here it is, in black and white…. This wonderful little equation describes how hair, blood, collagen or any other protein denatures as a function of time and temperature. It is important to understand how this works if you want to treat these proteins properly. Most people have never even heard of it, yet… Continue reading Tissue denaturation – the process
Laser Hair Removal and Tattoos
Via Laser Hair Removal and Tattoos Don’t Mix | Murphy Battista LLP Absolutely! You cannot use an IPL to treat hair above a tattoo! The pulse duration is far too long for the tattoo. Scar-free tattoo removal by laser is successful because most of the heat energy generated on the surface of the tattoo ink… Continue reading Laser Hair Removal and Tattoos
Advanced Laser-Tissue Interactions Course
New Advanced Laser-Tissue Interactions Course Finally, a course designed to outline a deeper understanding of the processes involved when applying laser/IPL energy to the skin. Topics include: Light transport in tissues; Thermodynamic effects; Selective Photothermolysis; Tissue denaturation; Arrhenius damage integral….. And more! Using recently developed computer models this course describes the more important processes… Continue reading Advanced Laser-Tissue Interactions Course
LSO (Laser Safety Officer) Training
I’ll open with the fact that I am a Certified Laser Protection Adviser (LPA) and a committee member of the Association of Laser Safety Professionals. I am also a member of ASLMS, the BMLA and the ELA. As such, I can go into a laser/IPL centre and carry out a safety assessment to ensure that… Continue reading LSO (Laser Safety Officer) Training
