There are also no puffs of smoke, and no strong smell of burned hair. After treatment the skin looks like it's not been touched.
Anyway, I have now had 5 treatments with this laser on my legs. The operator stops a little way from the top of my leg, so I still have a small patch to remind me what my leg hair used to look like. This allowed me to take the following comparison photographs, which some may find interesting. Each one is a patch of skin about 3.5 * 2.5 cm.
My whole leg used to be like this
As can be seen, the hair has not been eliminated - in fact, there appears to be very little overall reduction in the amount, but what it has done is made the growth far weaker. I can not shave my legs for several weeks and now look like a woman who hasn't shaved her legs, rather than a woman with a man's legs, which is a definite bonus. I know people who have recently started using this technology on the face, and it will be interesting to see if it does manage to clear the hair, or whether it does something similar to this and makes it "weaker". On the legs this is quite a desirable result (can still use the hair to keep warm in winter), but on the face, perhaps less so.
