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…

What are the three most important factors in laser/IPL hair removal?
Laser/IPL hair removal has a wide range of outcomes! Sometimes the results are great, sometimes, not so good. Why is this? The treatment requires that the germ/stem cells are irreversibly denatured – ‘cooked’ – sufficiently so that they cannot regrow the follicle. This can only be done with the correct level of fluence, which depends… Continue reading What are the three most important factors in laser/IPL hair removal?
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?
