What is a cold sore?
Cold sores are small blisters caused by the herpes simplex type 1 (HSV-1) virus. They’re highly contagious and can be transmitted through close contact with the virus or genetics. There are typically 6 phases to a cold sore:


Phase 1: Tingling or itching around the mouth.
Phase 2: Red blisters begin to form.
Phase 3: Cold sore appears.
Phase 4: Blisters split, leaving small red gashes. At this phase, a cold sore is at its most painful and transmittable.
Phase 5: Lesion collapses, leaving a yellow crust. When yellow crust falls away, area becomes tender.
Phase 6: Irritation fades as immune system returns cold sore to an inactive state.

Where do I apply clera?
clera is a topical agent for lips and face only and should not be ingested. Ensure clera™ is applied on affected area only. Do NOT apply inside the mouth. Avoid application in or near the eyes, as it may cause irritation. Should contact occur, rinse thoroughly with water. Discontinue use and consult a doctor if excessive skin irritation develops or increases.
How fast does clera work?

When do I begin treatment?
Keep clera close by at all times to prevent cold sores from appearing. Begin treatment at the first symptoms or signs of an episode, such as burning, redness, itching or tingling.
What happens if I pick or squeeze my cold sore?
Do not pick or squeeze the cold sore. This will cause scarring and delay healing.
What are the steps for applying clera?

  1. Wash your hands thoroughly and remove any cosmetics.
  2. Apply 1-2 drops of clera directly to the cold sore using the tip of your finger or a clean cotton swab and rub it in.
  3. Repeat application 2-8 times per day until the lesion is healed, up to a maximum of 10 days.
  4. To avoid contaminating the tip of the tube, wash your hands again before placing the cap back on.
