Something a bit different this year. With a pumpkin. And a laser… Incidentally, no pumpkins were harmed in the making of this video. Apart from that one, of course… Me bad, Mike.

“IPLs don’t work”, they say. ‘They’ are wrong. Here’s some proof…
I often hear people saying that “IPLs don’t work”. That’s not true. They are usually basing this on poor results which occur because of poor training. It seems to me that most people using IPLs out there are not properly trained! Hence the poor results… Here is an example of a good result with an… Continue reading “IPLs don’t work”, they say. ‘They’ are wrong. Here’s some proof…
Pain and laser/IPL hair removal
Following on from my post of yesterday about the penetration of fluence into the skin, a few people were asking about the pain experienced by patients/clients. I had pointed out that a single pulse of 30 J/cm2 is much more effective than three pulses of 10 J/cm2 – regardless of whether its from a laser… Continue reading Pain and laser/IPL hair removal
Is 30 J/cm^2 ‘better’ than three shots of 10 J/cm^2 in laser/IPL hair removal?
Answer – yes!! Why? OK, so we need to look at where the light goes in the skin to answer that question… Someone asked me, recently, the above question relating to the treatment of hair. She said that she had been trained to apply three shots of 10 J/cm2 to the area, rather than one… Continue reading Is 30 J/cm^2 ‘better’ than three shots of 10 J/cm^2 in laser/IPL hair removal?
Cómo mejorar la eficiencia de la depilación láser
Aquí está mi publicación más reciente en español, por pedido especial. La depilación láser/IPL puede ser “complicada”. Hay una serie de cuestiones a considerar, incluido el color y la profundidad del cabello, el color de la piel, el ciclo de crecimiento del cabello, las áreas del cuerpo, la fluencia, el ancho del pulso, etc., etc.… Continue reading Cómo mejorar la eficiencia de la depilación láser
How do we improve the overall efficiency of laser/IPL hair removal?
Laser/IPL hair removal can be ‘tricky’. There are a number of issues to be consider including hair colour and depth, skin colour, hair growth cycle, body area, fluence, pulsewidth etc etc etc… My calculations show that the ‘standard’ efficiency, when trying to kill hair follicles, out there is typically between 50 and 60%. In other… Continue reading How do we improve the overall efficiency of laser/IPL hair removal?
More on tattoo ink colours and fluence
I recently wrote about how we can use any wavelength to target any tattoo ink colour. It seemed to touch a raw nerve as quite a few people didn’t agree with my findings. So, I thought I’d elucidate with a wee bit of physics… And I know how much y’all love physics!! Physics Back to… Continue reading More on tattoo ink colours and fluence
Tattoo ink colours – which laser wavelength is “best”?
This thorny issue again! I was training someone recently and discussed the data in the table below. This comes from my calculations (click here for more on this) based on previous clinical studies. While discussing this table, I realised something interesting. As I’ve mentioned previously, any tattoo ink colour can be ‘treated’ by any wavelength.… Continue reading Tattoo ink colours – which laser wavelength is “best”?
