Lasers can effectively remove ulcers and cold sores with minimal discomfort and no scarring.
Clinical research has found that certain lasers are highly effective at treating aphthae and the herpes simplex virus. Patients treated with the laser see immediate pain relief, accelerated healing and reduced outbreaks in the future. Laser treatments will normally require 2-4 applications of laser energy to see the desired results.
For treating Herpes Simplex Virus 1 – if the laser treatment is done during the prodromal stage before the cold sores break out, then nearly all patients will heal within the first 48 hours. If laser treatment is done after the sores have already blistered or crusted, more than 90% of patients see the cold sores healed within 48 hours of treatment. For the remaining 10% of cases, the cold sores are healed within 4 days.
