Treating nasal thread veins with an IPL
IPL devices output a broad range of wavelengths which can be used to treat hair, blood vessels and pigmentation. We know that blood absorbs yellow light very strongly – typically in the region 500 to 600 nm (or thereabouts!) I trained some ladies (in ‘Mona Permanent Cosmetics’), recently, to use their IPL for telangiectasias (thread… Continue reading Treating nasal thread veins with an IPL
How Many Laser/IPL Hair Removal Sessions do I need to get a Good Result?
I’m often asked ‘how many hair removal sessions will I need using laser or IPL?’ This is not an easy question to answer because it depends on a high number of variables including your equipment, your training and, of course, your patient/client. But, I have tried to answer this question using a computer model of… Continue reading How Many Laser/IPL Hair Removal Sessions do I need to get a Good Result?

How much light energy actually emerges from IPL filters and reaches the skin surface?
When we set a fluence on an IPL unit, it is based on ALL of the light energy coming from the handpiece. However, each filter will absorb some of that energy – it is supposed to! The filters are designed to ‘block’ certain wavelengths, so that only the desired wavelengths reach the skin surface. So,… Continue reading How much light energy actually emerges from IPL filters and reaches the skin surface?
Laser/IPL Hair Removal – How many follicles do we kill each treatment?
All hair follicles grow according to a cycle – ‘anagen, catagen, telogen’. The follicle germative cells promote anagen hair growth at consistently regular intervals resulting in periods of active growth, followed by inactivity. The duration of these periods depends on the which part of the body is being considered. I created a computer model to… Continue reading Laser/IPL Hair Removal – How many follicles do we kill each treatment?
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.
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
Thick and thin hair – how much light energy do they actually absorb during photothermal treatments?
How thick is a hair? Well, according to some research by physicist, Brian Ley (they do all the best research!!!), it ranges between 17 and 181 microns in diameter (see his results here). That is between 0.017 and 0.18 mm. So, that means that their cross-sectional areas [A = pi x (radius)2] are between 0.0000023 and 0.00026 square… Continue reading Thick and thin hair – how much light energy do they actually absorb during photothermal treatments?
