What is the risk of ‘burning’ the skin with a laser or IPL?

Many people are worried about ‘burning’ the skin during laser/IPL treatment of hair, tattoos, blood vessels etc. But, what is the actual risk? Well, we can work this out knowing the skin colour and the applied fluence. Now, as many of you already know, I don’t like the Fitzpatrick Scale because it does not determine… Continue reading What is the risk of ‘burning’ the skin with a laser or IPL?

What are the threshold (minimum) fluences needed to ensure successful hair removal?

This is not easy to determine! It depends on the type of device you are using – IPL, diode, alexandrite, Nd:YAG laser. It depends on the depth of the follicles. It depends on the hair colour. I built a computer model to try to calculate these fluences. It considers all of the above, but today… Continue reading What are the threshold (minimum) fluences needed to ensure successful hair removal?

The WRONG way to do laser tattoo removal!

It appears many people are using their tattoo laser wrongly! They are holding it off the skin, up to 10 to 20cm away. This is just wrong!! By doing this they will invariably apply a very small spot diameter at the skin surface which generates a huge fluence (energy density). Such fluences can easily damage… Continue reading The WRONG way to do laser tattoo removal!

Treating blood vessels with an IPL

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.

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?
