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
Finally, I’ve caught up with Zoom! I can now offer my training courses online in a one-to-one situation. You can ask me questions during the course whenever you like. Plus, you don’t need to have Zoom on your computer!! I prefer to do these courses with a small group of people – no more… Continue reading One-to-one online training now available
Terrible name! Thank goodness we dropped it. Back in 1996 we were developing the world’s first IPL system for hair removal. Except, back in 1996 the name ‘IPL’ had not been coined! We were using a strange expression – “supraherence”. I honestly can’t remember why we came up with that!! We had done a… Continue reading Before ‘IPL’, there was ‘Supraherence’!!
I recently published an article in the Aesthetics magazine (Volume 7, Issue 3, Feb 2020) showing my results with a new masking technique in the treatment of angiomas and benign pigmented lesions – click here for my article. In it I show how higher fluences and longer pulsewidths may be used to treat small… Continue reading New IPL Masking Technique
Using IPLs on vascular and pigmented lesions can be very successful when the correct parameters are used. My theoretical research clearly shows that longer pulses are ‘better’ than shorter ones, when dealing with small and large targets. In order to test this I submitted my lovely wife to a series of treatments on her angiomas… Continue reading My ‘Hole in a Stick’ technique…
