Which are the most ‘aggressive’ wavelengths?

Posted in Interesting stuffLeave a comment

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?

Synchronised hair growth vs paradoxical hypertrichosis

Posted in Interesting stuffLeave a comment

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

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????!!!

Fluence, pulsewidths, temperatures and cellular denaturation

This topic is very poorly understood. How does fluence and pulsewidth relate to cellular denaturation – or, ‘cooking’ of the cells. I’m going to portray this in a series of graphs – I hope this works… When we fire light energy into the skin, we can generate some heating, if there is something in there… Continue reading Fluence, pulsewidths, temperatures and cellular denaturation

Hair removal – how does fluence relate to depth?

Posted in Interesting stuff2 Comments

We all know that light energy can kill hair follicles. It has been around since about 1996. But, many people still don’t understand the relationship between fluence and depth in the skin. Let’s begin with fluence – what is it? Simply put, fluence is just the concentration of light energy on the skin surface. If… Continue reading Hair removal – how does fluence relate to depth?

Fitzpatrick Type – what does this really mean and how does it affect our laser/IPL skin treatments?

Posted in Interesting stuff2 Comments

Here we go again! Fitzpatrick – the most mis-understood concept in laser/IPL therapies. Everyone who does laser/IPL treatments on the skin talks about the “Fitzpatrick”. Yet most people don’t really know what it means! Here is my take: There are two things you MUST understand: Dr Fitzpatrick was an American dermatologist who devised a scale… Continue reading Fitzpatrick Type – what does this really mean and how does it affect our laser/IPL skin treatments?
