We all know that the choice of fluence and wavelength is important when treating hair with light energy. However, many believe that the fluence should be reduced when treating darker skin colours. This is fundamentally wrong!! The pain felt during laser/IPL hair treatments is principally due to the epidermal heating. As a direct consequence, darker… Continue reading Hair Removal – Why is it painful?
The latest chapter of our eBook is now available online for your perusal. We have ‘hidden’ some pages – the ‘best’ ones, in our opinion, because we don’t want to give away all the good stuff too cheaply… This is the online pdf version which is outlines most of the contents. It will give you… Continue reading Fundamentals of Laser/IPL Hair Removal – online now!
After much gnashing of teeth and chasing of couriers, our eBook is now finally availabe in hardback format! All attendees of our MasterClasses will receive a copy automatically – the Birmingham peeps will be receiving theirs soon. We will soon announce a page where you can purchase these books, if you so desire… Mike. PS… Continue reading Finally… Our laser/IPL book is in hardback, printed form…
We often hear about “pain-free” laser/IPL hair treatments. And we hear, often, that they are not!! Why are they painful in the first place? What causes this pain and where exactly is it located? Here’s a wee video I made to try to explain this… Knowing this makes it easier to control the amount of… Continue reading Why are laser/IPL hair removal treatments painful? And how do we minimise it?
This is an interesting post! In it I will introduce one of my oldest customers – Marlon, from SkinteX Clinic in Glasgow. His is an unusual route into this industry. He has been an IT consultant, a driving instructor and a circus lion-tamer. About 9 years ago he decided that a life in the beauty… Continue reading IPL Hair Removal – How to achieve good results, from an expert – Marlon!
For years I have been teaching people to pre-cool the skin surface before firing laser or IPL energy into the skin when treating hair. And I’ve always suggested pre-cooling for between 2 and 5 seconds. My thinking was that we should not “over-cool” the skin because that might lower the temperature of the hair follicle… Continue reading It is impossible to ‘over-cool’ the skin when treating hair with lasers or IPLs
The fluence must be chosen to kill the germ cells in the target follicles. Those are the real targets – not the melanin in the hair shaft. The melanin can be viewed as a surrogate which we can heat using light energy. But, the germ cells do not have a chromophore which we can exploit… Continue reading Why we should NOT reduce the fluence when treating darker skins!!!
When photons (light) enter the skin they can undergo only two processes – absorption or scattering. Once a photon is absorbed, its energy is ‘gained’ by the absorbing site. This may be a melanosome in the epidermal basal layer (see figure 1 – ‘Epidermal absorption’). This absorption will transfer the photon’s energy into the melanin… Continue reading Where do photons go in the skin?
I read an interesting paper on this topic, last week. It was a clinical study looking into the application of ‘super hair removal’ using a low fluence output from a diode laser. As you may already know, I’m not a big fan of this technique. I feel that it is ‘tricky’ to administer properly and… Continue reading SHR/In-motion tehcnique – an update
Here’s a strange thing…. When we fire a laser or an IPL at the skin surface we usually know the fluence that is applied. So, we figure that a 10 J/cm2 will penetrate into the skin and diminish with depth. Well, bizarrely, it doesn’t!! This is entirely due to scattering. So, what is scattering? The… Continue reading How can there be more fluence inside the skin than is applied at the surface???
