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! Here is my take: There are two things you MUST understand: Dr Fitzpatrick was an American dermatologist who devised a scale… Continue reading Fitzpatrick Type – what does this really mean and how does it affect our laser/IPL skin treatments?
Human retinal sensitivity to wavelengths
Most people can see a wide range of coloured light, from around 350 up to 750nm. But, our sensitivity is not the same for all colours. Our human retina sees different colours differently. The graph below shows how this is – we see violet very poorly. Likewise with the ‘deep’ reds, out at 700+ nm.… Continue reading Human retinal sensitivity to wavelengths
Why does spot size affect penetration depth?
This is a little tricky because it’s not intuitive. We know, from both clinical tests and computer modelling, that larger spot sizes result in more energy/fluence reaching deeper into the dermis. But how does that happen? Well, it all comes down to scattering. The dermis is mostly composed of collagen fibres. These fibres are all… Continue reading Why does spot size affect penetration depth?

Laser Hair Removal – Dodgy practices and con-artists…
I don’t usually write this sort of thing, but I feel I must… In the last few years I have heard consistent stories about some salons/clinics in the UK offering deals on laser hair removal, with very poor, or non-existent, clinical results. One of my daughter’s friends experienced this recently. These centres appear to be… Continue reading Laser Hair Removal – Dodgy practices and con-artists…
Hair removal – Diode, Nd:YAG or Alexandrite lasers. Or IPLs? Which is “best”?
Hair removal using light is currently the most popular aesthetic treatment on the planet today, apparently. These days we use diode, alexandrite and Nd:YAG lasers and IPL systems. But there appears to be some confusion over these different devices, with all sorts of dubious claims. Let’s go back to first principles… How does this treatment… Continue reading Hair removal – Diode, Nd:YAG or Alexandrite lasers. Or IPLs? Which is “best”?
Laser/IPL Hair Removal – A new idea…
I was training a young lady on IPL hair removal, earlier today. Her name is Helen Hugill. During our sessions she asked me a question about waxing after treatments. I had pointed out that waxing should not be done by clients/patients before any laser/IPL hair treatments since it would remove the target melanin. She asked… Continue reading Laser/IPL Hair Removal – A new idea…

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.
