After shaving and letting the stubble return I've been using an IPL laser for a bit less than a year. In between IPL treatments I use an electric shaver, and I also pluck my nipple area which keeps the auroras really smooth.
The IPL has made the hair thinner in overall density, and the hair that remains is lighter / finer and the electric razor does a good job of keeping me visually clear but there's always stubble. I hope that the chest hair goes away completely after a time like it has on my legs.
