Chapter 3 – Fundamentals of Laser/IPL Hair Removal 2nd Edition
What is actually coming out of these devices?
We have measured the outputs from many systems through the last 30+ years using various meters. Our conclusion is not very good – many systems do not output what they claim! We have found many IPL systems delivering as little as 30% of the claimed fluence, even when new! So, you may set a desired fluence of, say, 30 J/cm2, on your screen, but the device only delivers 10 J/cm2.
Without the proper meter, it is almost impossible to tell. The only way to know for sure, is to hire an engineer and get your system checked. You should do this fairly regularly, depending on how much you use your device.
One way to tell if there is a problem, is by an increasing number of disgruntled patients/clients. If you detect an increase in this number, call an engineer. Soon!!
Conclusions
In this Chapter on laser/IPL hair removal we have discussed some of the basics behind:
Laser/IPL parameters Different technologies Treatment timings
Stamping vs SHR/In-motion techniques Selective Photothermolysis Tissue denaturation
These are all important to understand if you wish to have a successful career in medical/aesthetic laser/IPL treatments. Many users don’t have a sufficient knowledge of many of these concepts, and, as such, encounter all sorts of problems which lead to unwanted tissue damage, angry clients/patients and loss of business and reputation.
The most important things to consider, when treating hair, is that the fluence determines the success rate; skin surface cooling determines the amount of skin damage and the interval between treatment sessions determines the total number of sessions required. If you keep these in mind, then you should do well.
