A cold sore is a blister that usually forms on or around the lips and is usually caused by HSV-1.

Most cold sore sufferers aren’t exactly sure when they first encountered HSV-1. This is because the HSV-1 infection is usually contracted early in childhood and may not result in a visible cold sore outbreak. The virus will stay “asleep” until the secondary infection. 

During a cold sore outbreak, which often occurs after you have experienced one of the cold sore triggers, the virus “wakes up” and infects the skin cells in or around your lip or mouth, eventually becoming a visible and contagious sore. By using Abreva® cream at the first tingle,* you can help shorten the healing time of your cold sore cycle.

That’s because Abreva® cream is the only FDA-approved, non-prescription cold sore medicine that shortens healing time. In fact, only Abreva® cream penetrates deep and starts to work immediately to block the cold sore virus.* It could help knock out the cold sore in 2½ days, when used at the first sign.** Nothing heals faster among non-prescription products.

* Based on laboratory studies.
** Median healing time 4.1 days. 25% of users healed in 2.5 days.
