How to apply the ‘SHR’ and ‘stamping’ technques properly during hair removal – my videos

Laser/IPL operators often use the ‘SHR’ or ‘stamping’ techniques when applying their devices to hair removal on the skin. But I often see people using the wrong approach. This will, inevitably, lead to poor results or an excessive number of treatment sessions. In this video I explain how to apply these technique correctly, to increase… Continue reading How to apply the ‘SHR’ and ‘stamping’ technques properly during hair removal – my videos

Tattoo ink colours, absorptions and fluences…

An excellent clinical report by Scheibner (SCHEIBNER, A., KENNY, G., WHITE, W. and WHEELAND, R.G. (1990), A Superior Method of Tattoo Removal Using the Q-Switched Ruby Laser.) found that the minimum fluence required to induce a good reaction from black tattoo ink, using a Q-switched ruby laser, was 2 Joules/cm2. This threshold fluence was for… Continue reading Tattoo ink colours, absorptions and fluences…

Hair Removal – Why is it painful?

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?

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?

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!

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?
