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?

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?

“Pain free” hair removal. Is it real?

We often hear, these days, about “pain free” hair removal, with various lasers, usually diodes. But, is it true? Well, let’s look at this more closely… The aim with laser, or IPL, treatment of hair is to induce enough heat in the stem cells that stimulate hair growth in the follicles. To do this, we… Continue reading “Pain free” hair removal. Is it real?

Selective Photothermolysis – an in-depth explanation

Back in 2016 (I think) I gave a talk to the American Society of Lasers Surgery and Medicine about the theory of Selective Photothermolysis. This is the theory which underpins all of today’s photothermal laser/IPL treatments. In this talk I discuss the idea behind thermal relaxation time and how it ‘fits’ with treatments. In fact,… Continue reading Selective Photothermolysis – an in-depth explanation
