Personally, I use the Q-Switch laser to treat PIH and as Dr Wu has mentioned, there is no scabbing/downtime involved as compared to other lasers that are used for mole removal.
The Q-switch laser breaks down the pigment into smaller fragments so that your body can remove them. Multiple sessions will be required to speed up the lightening process and results can be seen typically within a month.
Hope that helps.
All the best.
