How effective is a cold sore laser treatment?

Laser treatments are very effective for treating cold sore outbreaks. Clinical research on the topic demonstrates that when patients were treated before the cold sores had formed---the outbreak severity was reduced and typically lasted only two days before the sores had healed.  For patients who had laser treatment after a cold sore outbreak – 90% of those had the sores heal within 48 hours of treatment. The remaining 10% of patients – the sores healed within 4 days – significantly less time than when the virus was left untreated.

What are cold sores?

Also known as "fever blisters", Cold Sores are a painful, embarrassing AND highly contagious blister that can form on the lips, chin, cheeks, and chin. They typically last two to three weeks if not treated. Laser therapy is a great option to help treat cold sores in their early stages. If early enough our lasers can effectively treat and speed up your healing time.

I have a cold sore. Now what?

Start your laser treatment as soon as you feel the first tell-tale signs and symptoms: itching, tingling, slight burning in the same area(s) as you had your last outbreak.  Cold sores are best treated and kept under control in their early stages. Laser therapy can keep an outbreak from occurring if caught in time. As soon as you feel the sensations of tingling, itching or pain in a previous outbreak area, you should email us: to schedule an immediate appointment.  It's easy.

Treatment Expectations?

  • Significant reduction and/or removal of pain normally caused by cold sores

  • If laser treatment starts on Day 1 of symptoms (Stage 1: itching, tingling prior to visible symptoms), it is possible to stop breakout from occuring.  Pain, itching and tingling are usually significantly reduced or stopped.

  • If laser treatment starts on Days 2-3---you should expect: immediate reduction of pain, slowing/stoppage of progressing visible symptoms, reduction of the size of affected area

  • Left untreated, cold sores typically resolve in 12-16 days.  Laser treatment can significantly reduce this to 4-8 days---with the added benefits of: reduced pain and tingling, AND smaller affected area (less visible symptoms)

How many treatments will I need?

Most clients require 1-3 treatments for satisfactory results.  This often depends on how soon laser treatment begins after appearance of your first symptoms.  The best case scenario is that we are able to treat you on day 1 of symptoms (itching/tingling in skin) which often occurs 12-24 hours before visible symptoms have appeared.

How much does treatment cost?

First Treatment: $100, Second Treatment (if needed: $75), Third Treatment (if needed: $50)

Does laser treatment of cold sores hurt?

The short answer is NO.  During laser treatment, you will experience some warmth---and occasional a hot sensation over the most pain-sensitive areas.  It is short-lasting, and does not linger.  After laser treatment, the nerve cells around the area are deadened which provides instant pain relief.   

How long does treatment take?

Laser treatment of cold sores takes 20 minutes or less.  

How do I get best results?

Best results can be achieved by:

  • Start your laser treatment as soon as you feel the first signs of itching and/or tingling

  • Combine laser therapy with anti-viral creams or pills: Examples include Valtrex, Denavir, Zovirax (acyclovir)....You will need a prescription from your family doctor for these products.  Abreva is currently the only non-prescription medicine available OTC (over-the-counter in Ontario, Canada.
