I have just been alerted to a new government warning about this device. I wrote about it last year (April 2024) pointing out that I thought it was not what they claimed and also potentially dangerous. You can find that post here – https://mikemurphyblog.com/2024/04/08/testing-the-neatcell-picosecond-laser-pen-device/ Well, a colleague alerted me to the fact that the UK… Continue reading Neatcell “Picosecond Laser Pen” – Update

How does fluence change in the skin and why can this stop good results when treating hair, tattoos or blood vessels?
The way light moves through the skin is quite complex. When photons ‘meet’ atoms they can either be absorbed, scattered or completely ignored. This may happen many millions of times, or, sometimes, only once! The effect these events have on the fluence (energy concentration) can be quite marked. In this video I explain what can… Continue reading How does fluence change in the skin and why can this stop good results when treating hair, tattoos or blood vessels?

Two new videos – “Chasing the crack” and “Skin tones and fluence”
I was bored today, so I thought I’d make a couple of wee videos. The first one is about why we must apply our lasers at the skin surface properly, particularly with tattoo lasers. We DO NOT want to hear the ‘cracking; sound – that is completely wrong. The second video is about the relationship… Continue reading Two new videos – “Chasing the crack” and “Skin tones and fluence”

The hair growth cycle in humans
Human hair grows according to a cycle. This cycle can be broken down into three main phases – anagen, catagen and telogen. To understand this process, we need to look closely at the follicles, and their structure. All follicles are comprised of two distinct parts – the upper, permanent part which includes the stem cell… Continue reading The hair growth cycle in humans
The “Hairy Trinity” – How are fluence, follicle depth and treatment frequency related in hair removal treatments?
As many of you know, I like to build and develop computer models investigating how light energy interacts with skin constituents etc. I’ve been doing this since 1987 and am now beginning to get the hang of it!! One model I built, a few years ago, looked at the hair growth cycles across the body.… Continue reading The “Hairy Trinity” – How are fluence, follicle depth and treatment frequency related in hair removal treatments?
Fitzpatrick Type – what does this really mean and how does it affect our laser/IPL skin treatments?
Here we go again! Fitzpatrick – the most mis-understood concept in laser/IPL therapies. Everyone who does laser/IPL treatments on the skin talks about the “Fitzpatrick”. Yet most people don’t really know what it means!
