Cold sores: the biggest benefit comes from starting early

Cold sores often begin with tingling, burning, or itching at the lip edge before the blisters appear. Acting at that early stage usually gives the best chance of keeping the outbreak smaller and less bothersome.

The most useful products are the ones that are easy to start using right away. If treatment stays in the drawer until the blister is already obvious, the benefit is often smaller than it could have been.

Keeping the lip clean and dry helps, and it is wise not to touch or share lip products, towels, or other personal items. The routine around the sore matters almost as much as the local product itself.

If sores come back very often, are unusually strong, or appear close to the eye, the situation should be checked. Cold sores are common, but not every outbreak should be treated as routine.
