Someone recently asked me ‘which is the most aggressive wavelength for the skin?’ That’s interesting question… We should first start by identifying which wavelengths we need to consider. In many skin treatments we use visible and near-infrared light – from around 400 nm up to 1064 nm (Nd:YAG) or even 2940 nm (erbium:YAG). CO2 lasers… Continue reading Which are the most ‘aggressive’ wavelengths?
My books and free booklets –
Here is a link to some of my books etc… In the above link you will find my books free downloadable pdf books (the hardbacks cost actual money!!) and my free booklets. I hope you find them useful. Mike.
Synchronised hair growth vs paradoxical hypertrichosis
These days, we see many claims of ‘paradoxical hypertrichosis’. Most of the time, these claims are inaccurate – they are not seeing this at all. So, what do these terms actually mean? Let’s define these two terms… Paradoxical hypertrichosis PH (I can’t be bothered writing this out all the time!) occurs when hairs are observed… Continue reading Synchronised hair growth vs paradoxical hypertrichosis
What is a laser? Back to basics…
In our latest podcast, we discuss what lasers are and how they work. It’s all about electrons and photons and other groovy quantum mechanical stuff. Another one in our series of ‘Explain Like I’m 5’ episodes… Hope you enjoy, Mike.
New published paper – how the wavelength of light changes when it enters and traverses through the skin
The wavelength of light changes when it moves from one medium into another. This includes moving from the air into the skin. This is due to the change in refractive index between the air and the skin. It happens all the time whenever light changes media. You can read our paper here… What does this… Continue reading New published paper – how the wavelength of light changes when it enters and traverses through the skin
Our first VTCT trainees passed!!
We are delighted to announce that our very first VTCT Level 4 ‘Laser and Light’ trainees, Kate and Tracey, passed their assessments and exams in our centre in Glasgow, yesterday. This is our first foray into this world of VTCT stuff and, I think, we did quite well. Special thanks to my lovely daughter, Lisa,… Continue reading Our first VTCT trainees passed!!
Our latest podcast – skin cooling. Who needs it?
I seem to bang on and on about this all the time!! Yes, I do. Why? Well, it’s quite simple – to successfully treat unwanted hairs and blood vessels in the skin, we need to ‘cook’ them until they die. That usually means inducing a fairly high temperature in those targets. But, if we do… Continue reading Our latest podcast – skin cooling. Who needs it?
“Plume” – is it a hazard?
YES!!! It sure is. Research has found that laser/IPL plume can contain some real nasty substances including carcinogenic biomaterials and toxic stuff. We really do not want to be breathing this in routinely. So, we’ve put together a wee booklet – free to download (see below the image) – which explains what plume is and… Continue reading “Plume” – is it a hazard?
Who needs to cool the skin before lasering????!!!
I just read a comment from a laser hair removal practitioner who was told, by a client, that she had been in another clinic and told that the “results would be better” if she opted not to use the cryogen. In other words, no skin cooling! Clearly that laser tech does not understand what is… Continue reading Who needs to cool the skin before lasering????!!!
Do we treat a tanned skin with our lasers and IPLs?
Now, there’s a question! During our recent sunny weather here, some people exposed themselves to too much ultraviolet radiation – they got a tan!! Does this mean we cannot treat them with laser and IPLs? Let’s discuss… We hope you enjoy, Mike.
