So I have booked the PDL (Regenlite). A package of 6 Regenlite and 6 Revlite (advanced Q-switch laser?) is offered (12 Regenlite if omit the other). I'm told Regenlite is for killing bacteria, Revlite is for cleaning.. but all I'm expecting is only getting rid of new acne, would the cleaning laser be necessary? They're suggested once every 2 weeks (assuming Revlite is involved), in turns. But some say PDL can prevent acne for roughly 3 months? What would be your suggestions? Thanks a lot!!
