How Long Will It Take PIH Caused by IPL to Resolve?
I had IPL on my neck, shoulders and chest with an Alma Hamony device. I experienced good results with my first treatment, but the energy level was increased for my second treatment, and it caused excessive heating and PIH in three areas (shoulders were fine, but the sides and back of my neck were not). I have been battling PIH for three months now. I have tried a combo kojic acid, glycolic acid, Retin-A, and hydroquinone, with little success except skin mottling. Will it ever resolve?
