Our training is “wrong” according to a laser supplier! Here’s our reply…

Recently, one of our clients was told, by her laser supplier, that our training is “wrong”. I am happy to receive criticism, as long as it is justified. However, this particular criticism was just nonsense! So Lisa and I decided to discuss it in one of our podcast episodes… Unfortunately, there are some laser suppliers… Continue reading Our training is “wrong” according to a laser supplier!

PMU inks – what is in them?

I recently came across an excellent book called “PMUni Colourant Manual” by Jasmine Diebelius which delves into the world of PMU inks and their constituents. In it, she indicates the pigments used to formulate many commonly-used PMU inks. This has proved very interesting to me, because of the ramifications for laser removal. In one section,… Continue reading PMU inks – what is in them?

How many treatment sessions does hair removal need?

This is a simple post. The number of laser/IPL sessions needed to remove hair follicles permanently depends entirely on the fluence you apply. That’s it – in a nutshell! As I’ve said before, a ‘low’ fluence can only affect follicles down to a certain depth. So this fluence can only kill a relatively small number… Continue reading How many treatment sessions does hair removal need?

Should we wax or pluck before laser/IPL hair removal? The science…

This is an interesting question. Virtually everyone’s initial response would be a resounding “NO”. “Why should we? We would be removing the target we are trying to destroy!!” Well, yes, of course. That’s obvious. Except, it isn’t… A telogen hair, about to transition into anagen 1. To answer this question properly, we need to look… Continue reading Should we wax or pluck before laser/IPL hair removal? The science…

Pulsewidths, thermal relaxation times and ‘cooking’ times in photothermal treatments

After my previous post, several people asked me to explain more about pulsewidths and thermal relaxation times, and how they relate to each other. The truth is, they are all unrelated!! They are intertwined, but not directly related. I thought it might be best to describe them using a bunch of graphs. So, I made… Continue reading Pulsewidths, thermal relaxation times and ‘cooking’ times in photothermal treatments

Fluence, pulsewidths, temperatures and cellular denaturation

This topic is very poorly understood. How does fluence and pulsewidth relate to cellular denaturation – or, ‘cooking’ of the cells. I’m going to portray this in a series of graphs – I hope this works… When we fire light energy into the skin, we can generate some heating, if there is something in there… Continue reading Fluence, pulsewidths, temperatures and cellular denaturation
