Though I hear the laser treatment works wonders for most people, its very expensive and painful for most. Acne laser treatments can cost anything from $250 to $3000 depending upon the procedure and the requirements. There are various types of laser treatment available – bluelight, pulsed light and heat, ALA and light therapy, photodynamic therapy (PDT), Photothermolysis etc. So before you do it, you should consult your dermatologist and read some acne laser treatment reviews.
