Immediately after a single treatment
The above shows the effects of a single treatment with four shots at 24 J/cm2 in a 30ms pulsewidth. We can see that there is clearly an improvement, but that they are still some vessels unaffected, while others were just shrunk. This is not unusual. This area had a number of vessels of various sizes. This indicates that a range of fluences and pulsewidths are required to effectively destroy them all. The deeper blue vessels are unlikely to be affected by this treatment as the light energy cannot reach them (with sufficient fluence).
With hindsight, we should have used more fluence on these vessels. I suspect a fluence of 30 to 34 J/cm2 would have removed most of these in a single treatment (except the deep blue ones!)
It is clearly possible to treat many blood vessels on the skin using IPL light energy, using the correct fluences and pulsewidths. These can be done with a single treatment in many cases.
I hope this helps you understand how we can achieve these results using a relatively simple technology.
