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
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

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
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
A brief history of my life in medical lasers and IPLs…
NEW Safety Glasses We can now offer new laser safety glasses for the 1064nm wavelength from Q-switched Nd:YAG lasers (typically used for tattoo removal). These new glasses (left) offer a much better visual inspection of the tattoo compared with the standard glasses (see below). However, they can ONLY be used for the 1064nm as they… Continue reading NEW Laser Safety Glasses for Nd:YAG systems
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!
This is mind-blowing….
Article A very interesting article written by a couple of my colleagues about the important issue of CE Marking of aesthetic lasers and IPL systems. Mike. firstname.lastname@example.org
