Why are laser/IPL hair removal treatments painful? And how do we minimise it?
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?
IPL Hair Removal – How to achieve good results, from an expert – Marlon!
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!
It is impossible to ‘over-cool’ the skin when treating hair with lasers or IPLs
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
Why we should NOT reduce the fluence when treating darker skins!!!
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!!!
Where do photons go in the skin?
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?
SHR/In-motion tehcnique – an update
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
How can there be more fluence inside the skin than is applied at the surface???
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???
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?
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!
