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 is probably my 2nd favorite item. I was blown away with this serum. I was just starting a cold sore, felt the bump on my lip, & grabbed the serum & dabbed it on. It did relieve that irritated feeling when you feel one starting to grow. The next morning I was surprised it hadn’t grown bigger or opened up! I dabbed the serum on again 3 diff. times that day. By day 3, it was pretty much gone, & never fully evolved!!! I was so pleasantly surprised! I will have to see how it helps when I have a full blown one. Something I will not let run out in my medicine chest.

    I’ve been using this combined with a daily dose of collagen to combat my coldsores. I was using Valacylovir at the first sign, but I’ve found the combo of a high dose collagen (or a really collagen rich diet) and this oil work just as well if not better than the heavy chemical products I was using. I think adding clove oil would be great for added numbing.

    I get cold sores often and this is my go-to at the first sign of one. Only wish it came in a roller bottle so I could carry it in my purse. It really helps get rid of them fast so I keep it on hand to use quickly.

    Love the taste & smell of this. It reminds me of watermelon. It does work really well. I think adding a little clove for extra numbing & pain relief would be great here.

    I have had cold sores for 23 years, yes I’m counting =) I have tried high dose of valtrex when I was younger, castor oil, abrevea, rubbing alcohol, ice cubes..list goes on. Nothing worked. I got a full blown one two days ago and bought this at my holistic practitioner the same day, applied it 3 times daily. Wow! Sore was full blown and now the inflammation is non existent, the itching and burning has stopped completely, all the symptoms of a cold sore is completely gone. By tomorrow (day 3) it will be completely gone. I give this a million stars.

    For years I’ve been using Abreva with just ok success for any cold sores I got. I thought I would give Earthley’s Cold Sore Serum a try and WOW it worked so much better for me. Within two days my cold sore was gone when normally it would take closer to two weeks to completely go away. This is a game changer for me and cold sores.

  7. Andrea Hicks

    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.
