Using IPLs on vascular and pigmented lesions can be very successful when the correct parameters are used. My theoretical research clearly shows that longer pulses are ‘better’ than shorter ones, when dealing with small and large targets. In order to test this I submitted my lovely wife to a series of treatments on her angiomas… Continue reading My ‘Hole in a Stick’ technique…

New Laser/IPL Training Website…
I have just built a new website for my training stuff – at dermalase-training.com. Go and have a wee look around please. Let me know any comments you may have… Cheers, Mike.
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……
Single or Double Rod Nd:YAG Lasers?
Nowadays, it is possible to purchase Q-switched Nd:YAG lasers with a single YAG rod, or with two rods. So, what is the difference and is it important? To understand why a laser might have two rods instead of one we should look at the basic design of a laser first. Basic laser cavity A… Continue reading Single or Double Rod Nd:YAG Lasers?
Refresher Courses
I can now offer the following ‘refresher courses’: Laser tattoo removal: Choosing the correct settings Which laser is best? How does it actually work? Ink colours Pain management Managing patient expectations Minimising risk Laser/IPL removal of hair, vessel, pigmentation + skin rejuvenation Choosing the correct settings… Understanding the light-tissue interactions The critical importance of… Continue reading Refresher Courses
Are you getting the best out of your IPL system? Most people don’t….
IPL systems can generate excellent results in many conditions, if used correctly. However, I constantly hear people telling me that they “can’t get good results” with theirs! Why is this? Well, basically it comes down to two main factors: either their equipment is not very good or cannot output a sufficient energy or… Continue reading Are you getting the best out of your IPL system?

More on Thermal Relaxation Times
TRTs I’ve had a number of enquiries about my article on the relevance of thermal relaxation times in photothermal treatments. They were asking for clarification. So here goes…. Thermal relaxation time (TRT) describes how quickly an object loses heat energy. Typically, it is the time taken for the temperature of an object to drop… Continue reading More on Thermal Relaxation Times
‘Lunch & Learn’ – Quick, lunchtime courses in lasers, IPLs, RF and their applications
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 time… Continue reading Thermal Relaxation Time – what is wrong with it?
