Blood aborbs light strongly in the region between about 500 and 600nm. The graph below shows this with both oxy- and deoxyhaemoglobin (the red and blue lines). We don’t use the lower wavelengths (below 450nm) because they are too near the blue/ultra-violet part of the spectrum! So, we can selectively target blood vessels using these… Continue reading Treating blood vessels with an IPL
Calculating the optimum intervals between hair removal sessions.
I am often asked, during training, “what is the best time to leave between laser/IPL treatment sessions?” This is actually quite tricky to answer. I wondered about this for some time and then realised that I had to build a computer model to answer it correctly. So, I used Excel and built such a model.… Continue reading Calculating the optimum intervals between hair removal sessions.
Thermal Relaxation Time – The Flaw in Selective Photothermolysis
I gave a talk at this year’s BMLA meeting in Edinburgh. It was on a topic close to my heart – the notion of thermal relaxation times and how they don’t apply to modern-day photo thermal treatments. Here it is… I hope that clears up a few things, Mike.

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?
What is the key to success with laser/IPL treatments?
The answer to this question is very simple – TEMPERATURE!! Think about what we’re trying to do when treating hair, blood vessel or benign pigmentation. We are trying to ‘kill’ certain cells, using heat. That’s why we fire laser light energy at them. We’re trying to force them to absorb that light energy, convert it… Continue reading What is the key to success with laser/IPL treatments?
Not all hair removal lasers and IPLs are the same!!
I’ve been doing a lot of work recently, looking at how lasers and IPLs differ when considering hair removal. They’re all different!! In various ways… Comparing diode lasers with Nd:YAG lasers with alexandrite lasers is like comparing chalk with cheeses. It is quite tricky trying to compare these devices properly. Add in IPLs and it… Continue reading Not all hair removal lasers and IPLs are the same!!
