I have been around since before the invention of colour…..!!! I have seen many excellent advances in the medical/aesthetic laser industry in that time. But I have also seen a few things which concern me greatly. Poor training I seem to be training more and more people who have already received ‘training’ on their lasers… Continue reading My concerns in today’s aesthetic industry…
I am asked this question all the time.. There is a lot of mis-understanding about the differences between lasers and IPLs, and how they interact with the skin. Some people think that lasers are “superior”, but this depends on what you’re targeting! I put together a wee animation (below) to try to explain some of… Continue reading Which is better – laser or IPL hair removal?

Hair grows in a well-known cycle – anagen, catagen and telogen. The ‘active’ growing phase is anagen – during this phase the hair follicle will begin to grow from a single stem cell. The duration of this phase depends on the body location and can range from a few weeks to several years! However, these… Continue reading The Hair Growth Cycle & Laser/IPL Treatments. When is the ‘best’ time to treat?
How do you know what fluence or energy is coming out of your IPL unit? Some devices will have an on-board meter, but many don’t. In that case, you really should get it properly calibrated. You can only do this with an appropriate meter which should be able to measure both the fluence and the… Continue reading Calibrating an IPL device
Most laser systems have a lens to focus the laser energy down to a sale spot diameter (see figure 1 below). However, in many systems, the focal point (where the spot diameter is the smallest) is outside the handpiece assembly. This has a potentially hazardous effect if not properly understood! The problem with this design… Continue reading Laser spot size – how it changes with distance from the target…
IPL systems typically use a Xenon flash lamp to generate light across a wide range of wavelengths, usually 400 to 1200 nm. To select a ‘useful’ range a filter is applied. These are generally ‘cut off’ filters which stop all wavelengths below a given value, from transmitting through. Hence, a 650 nm will stop all… Continue reading IPL filters
How do you calibrate your lasers so that the numbers on your laser screen actually mean something useful? Well, there is a process which you need to follow. The video shows this process in detail. So, you need to measure the laser energy for each of your ‘input’ settings using an energy meter designed for… Continue reading Calibrating your laser – making sense of the numbers…
I have been asked many times in the last few years for a recommendation for an introductory book describing the application of lasers and IPLs in aesthetic treatments. My answer was always the same – “There isn’t one!!” So, I finally took the plunge and decided to write one, with my colleague PA Torstensson. The… Continue reading New Book – Medical/Aesthetic Lasers & IPLs and Skin Treatments
