Hair removal using Diode lasers vs Nd:YAG, Alex lasers & IPLs

Hair Removal Systems These days there are a number of different systems available for hair removal, which can make it a bit tricky when deciding which to purchase. In particular, diode lasers are a different type of laser when compared to the other systems (and IPL). Here I outline some of the differences between these… Continue reading Hair removal using Diode lasers vs Nd:YAG, Alex lasers & IPLs

Applying the SHR technique properly to remove hair…

I’ve seen a lot of videos, recently, where laser operators are showing their prowess with laser hair removal, usualy with a diode laser. However, most of them are doing it wrong!! They are usually seen ‘scanning’ up and down an area, relatively slowly, firing off a whole bunch of pulses of laser energy. Unfortunately, this… Continue reading Applying the SHR technique properly to remove hair…

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?

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!!!
