What is happening with laser tattoo removal treatments? As we all know, the laser energy is absorbed by the tattoo inks, and they ‘break up’. Well, something like that… But what does ‘absorbed’ actually mean? And how much of the light energy is absorbed by each ink colour? To answer these questions, we need to… Continue reading Laser tattoo treatments – how do we approach different ink colours??? Part 1.

Why are some tattoo ink colours so difficult to remove?
Anyone performing laser tattoo removal will know that certain colours are a nightmare! But why is this? What is the science behind this problem? Well, it all comes down to ‘absorption coefficients’. These are the probabilities that an ink colour will absorb any particular wavelength. And, of course, they vary enormously!! Here’s a wee video… Continue reading Why are some tattoo ink colours so difficult to remove?
Manufacturers’ settings – what is wrong with these?
I reckon around 85% of my training clients have been previously trained elsewhere, often by their equipment suppliers/manufacturers. I always ask them why they have come to me when they have already been trained. Their answer is always the same – “I don’t understand what I’m doing!” One client had received her training from a… Continue reading Manufacturers’ settings – what is wrong with these?
What are the differences between lasers and IPLs?
I am asked this question often. So, I made a wee video to explain the main differences… I hope this makes things a bit clearer. Mike.

Tattoo ink colours, absorptions and fluences…
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…

How can there be more fluence inside the skin than is applied at the surface???
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???
The WRONG way to do laser tattoo removal!
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!
