What is the ‘best’ interval between hair removal sessions (after treatment by lasers or IPLs)? Part 2.

I wrote a blog post back in September 2021 discussing my thoughts on the how to determine the optimum interval between laser/IPL hair sessions. It proved very popular amongst my readers. But, as soon as I posted it I began to doubt my own conclusions. Back then I suggested that we should wait for an… Continue reading What is the ‘best’ interval between hair removal sessions (after treatment by lasers or IPLs)? Part 2.

How strongly are different laser wavelengths absorbed in melanin and blood?

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?

The world’s FIRST ever commercial laser tattoo patient…

The other day I was training some very nice ladies and showed them a couple of photos of a tattoo I had treated with a Q-switched ruby laser. I realised, as I was talking to them, that this tattoo was the very first tattoo to be treated in our new, commercial clinic. Prior to this… Continue reading The world’s FIRST ever commercial laser tattoo patient…

The ‘best’ way to cool the skin during laser/IPL treatments

Many laser and IPL treatments require a significant temperature rise in the target cells, to effectively kill them. We use light energy to induce this temperature rise. But, calculations show that, in some cases, less than 1% of the light energy is actually doing the job we want. That means that more than 99% of… Continue reading The ‘best’ way to cool the skin during laser/IPL treatments
