These are both divided by 'C', which is just a boring, old constant. Let's ignore this for the moment...
Yum!
So, this equation is telling us that the temperature rise generated by laser energy absorbed in any target is simply dependent on the product of the fluence and the 'colour'. This makes sense - darker hair are easy to remove compared with lighter hairs.
But what this equation also tells us is that the fluence is absolutely critical!
In fact, the success of ANY photo thermal treatment (by laser and/or IPL) depends strongly
on the temperature rise attained in the target.
