I had 6 years of IPL on my face and torso, one treatment (2 hr session) every 6 weeks.
After this, most of the hairs remaining were no longer dark, so I switched to electrolysis.
Had about 4 years of that at 1 treatment (1 hr session) per week.
Now I'm living "in stealth", I find it very difficult to let the hairs grow for any further treatment, so I spend between 30 mins and 1 hour every morning plucking the remaining regrowing hairs from my face.
Yeah, it sucks massively, and after about 4 days of plucking, I still need to shave my face with an electric razor.
Life huh?
