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
“No Pain, No Gain” – hair removal using light energy!
OK! PDF version This is really quite simple! Human thermal/pain receptors (nociceptors) are triggered at around 45 C. Below that temperature you feel heat – above it, and you feel pain. NASA has proved this beyond doubt! So, to achieve permanent, or even ‘semi-permanent’ hair removal you need to apply sufficient heat energy, for a… Continue reading “No Pain, No Gain” – hair removal using light energy!

Variable pulsewidth vascular system for dermatology | (1994) | Gustafsson | Publications | SPIE
via Variable pulsewidth vascular system for dermatology | (1994) | Gustafsson | Publications | Spie This report describes the world’s first IPL system, developed by Morgan Gustafsson in the early 1990s. Back then we didn’t call it IPL – that name came later. Morgan approached me at an ASLMS conference after I gave a… Continue reading Variable pulsewidth vascular system for dermatology | (1994) | Gustafsson | Publications | SPIE

Calculation of the clinical parameters to effect removal of Port Wine Stains | (1990) | MJ Murphy | Publications | SPIE
via Calculation of the clinical parameters to effect removal of port wine stains | (1990) | Murphy | Publications | Spie I started doing Monte Carlo and numerical thermal models in 1987 to try and figure out the ‘best’ set of laser parameters to treat PWS vessels. That was a long time ago! Since… Continue reading Calculation of the clinical parameters to effect removal of Port Wine Stains | (1990) | MJ Murphy | Publications | SPIE
Port Wine Stains: optical assessment and practical implementation of treatment | (1990) | MJ Murphy | Publications | SPIE
via Port wine stains: optical assessment and practical implementation of treatment | (1990) | Murphy | Publications | Spie A report I co-authored with some colleagues in Strathclyde University describing our attempts to treat PWS with Candela’s original pulsed dye laser, back in the mid 1980s. We designed a PC-operated scanning system to deliver… Continue reading Port Wine Stains: optical assessment and practical implementation of treatment | (1990) | MJ Murphy | Publications | SPIE
Eggs, and their Arrhenius Parameters
Eggs! Wonderful things. Scrambled, boiled, fried, curried…. Also, very useful to demonstrate the difference in the Arrhenius Parameters with different proteins. Eggs contain at least two sets of proteins – the yoke (also including some fat, vitamins, lecithin and minerals) and albumen (about 40 different proteins in the white). When we cook eggs we… Continue reading Eggs, and their Arrhenius Parameters
