I have an IPL device, I've tried it out once but didn't think it was for me. Since then I've tried shaving regularly (every other day) and waxing which nearly caused a panic attack, so I'm back to IPL.

I know I need to shave just before the IPL, which is fine, what I'm wondering is should I be able to see and feel results after the first treatment?

My device has 5 settings for strength, even after level 5 I could feel hair still, does the laser destroy the follicle over time, or in one zap? I know either way you need to repeat atleast once a week I just mean will a good device leave you smooth straight away or will it take a few sessions to really show?
