When to Seek Cold Sore Treatment
The sooner you treat a cold sore, the faster it heals. Call us at the first sign — ideally during the tingling stage before the sore fully forms.
Tingling or Burning Sensation
The earliest warning sign — if you feel tingling, itching, or burning around your lip, come in right away. Laser treatment at this stage can prevent the sore from fully forming.
Active Cold Sore
Even after a sore has appeared, laser treatment can significantly reduce pain and cut healing time — often by several days compared to letting it run its course.
Frequent Recurrences
If cold sores keep coming back in the same area, repeated laser treatments can help reduce their frequency and severity over time.
What Triggers Cold Sores?
Cold sores are caused by the herpes simplex virus (HSV-1), which stays dormant and can reactivate due to common everyday triggers. Understanding yours can help you act faster and reduce outbreaks. Common triggers include stress and fatigue, sun exposure, illness or fever, hormonal changes, lip injury or irritation, and a weakened immune system.

The earlier, the better. If you come in during the tingling or prodromal stage — before the sore fully forms — the laser can often prevent a full outbreak. Even during an active sore, treatment still significantly reduces pain and healing time.
Treatment is affordable and we provide clear pricing upfront. Wellness Plan members receive 25% off all treatments.
