Short answer - yes. However because the erbium component only goes to 100 microns, and the non ablative wavelength is energy and density controlled, you will need multiple sessions. Yes, it can be effective, but lasers such as Co2 are much better. In some cases patients may need surgery. One laser is never the answer to all problems, and an evaluation by a certified specialist will give you the best options. Kind regardsDR Davin Lim Brisbane, Australia.
