Last update – 29.1.23 Below are links to my blog posts… Laser/IPL Hair Removal Fundamentals of Laser/IPL Hair Removal – online now! Hair Removal – Why is it painful? Why are laser/IPL hair removal treatments painful? And how do we minimise it? “I’ve burnt my patient!!” With IPL treatments, that is precisely what we are tying to do… What… Continue reading Here is a list of my blog posts covering laser/IPL hair removal, tattoos, blood vessels, physics, MasterClasses and other stuff…
An excellent clinical report by Scheibner (SCHEIBNER, A., KENNY, G., WHITE, W. and WHEELAND, R.G. (1990), A Superior Method of Tattoo Removal Using the Q-Switched Ruby Laser.) found that the minimum fluence required to induce a good reaction from black tattoo ink, using a Q-switched ruby laser, was 2 Joules/cm2. This threshold fluence was for… Continue reading Tattoo ink colours, absorptions and fluences…
The latest chapter of our eBook is now available online for your perusal. We have ‘hidden’ some pages – the ‘best’ ones, in our opinion, because we don’t want to give away all the good stuff too cheaply… This is the online pdf version which is outlines most of the contents.

We will soon announce a page where you can purchase these books, if you so desire… Mike. PS… Continue reading Finally… Our laser/IPL book is in hardback, printed form…
Here’s a strange thing…. When we fire a laser or an IPL at the skin surface we usually know the fluence that is applied. So, we figure that a 10 J/cm2 will penetrate into the skin and diminish with depth. Well, bizarrely, it doesn’t!! This is entirely due to scattering. So, what is scattering? The… Continue reading How can there be more fluence inside the skin than is applied at the surface???
It appears many people are using their tattoo laser wrongly! They are holding it off the skin, up to 10 to 20cm away. This is just wrong!! By doing this they will invariably apply a very small spot diameter at the skin surface which generates a huge fluence (energy density). Such fluences can easily damage… Continue reading The WRONG way to do laser tattoo removal!

IPL devices output a broad range of wavelengths which can be used to treat hair, blood vessels and pigmentation. We know that blood absorbs yellow light very strongly – typically in the region 500 to 600 nm (or thereabouts!) I trained some ladies (in ‘Mona Permanent Cosmetics’), recently, to use their IPL for telangiectasias (thread… Continue reading Treating nasal thread veins with an IPL
The 1st DermaLase MasterClass wil be held in September this year in Birmingham. The detals of this event can be downloaded in a pdf format from here. Here is an outline of the topics which will be discussed – if you have a particular topic which you wish to be addressed, please let us know.… Continue reading MasterClass – Birmingham – Sept 2022 – Details
These days we use a wide variety of lasers and IPLs to treat various targets in the skin. Two major targets are hair and blood vessels. But how much of the laser/IPL light is actually absorbed by these targets? Using data from two very clever scientists (Steve Jacques and Scott Prahl) it is relatively easy… Continue reading How strongly are different laser wavelengths absorbed in melanin and blood?
