Asains are more at risk for hyperpigmentation with any type of laser. The settings need to be decreased slightly and hydoquinones need to be used before and after the procedure for several weeks. Acne scars are always tough, so at least 2 treatments should be planned because the doctor will be using lower settings than on lighter skin. Hyperpigmentation is usually reversible with hydroquinones if it does occur after a laser procedure. I don't know about the Korean machine.
