Use a clean finger to place a drop on the spot(s) 2-3 times per day or as needed. Do not allow the dropper to come in contact with the sores. Safe for use while pregnant and nursing.


Safe for ages 1+. Safe in pregnancy and breastfeeding.


Q: Do I apply this before or after my skin care routine is finished?

A: We recommend avoiding the area completely with your skin care routine so nothing is spread to the rest of your face and applying this after your routine is finished.

Q: Why can’t I touch the dropper to the area?

A: Cold sores are viral infections and touching the dropper to your cold sore runs the risk of transferring germs into the bottle.

Q: Can this be ingested?

A: Yes!

    This was a game changer. I’d had several horrible cold sores, and the local natural store brand treatment seemed to do nothing. But I used this on the last cold sore, and I didn’t get anywhere near as bad, and disappeared within a couple days.
