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 product actually does actually work for cold sores. I have tried a ton of essential oils to stop cold sores with little relief. The cold sore serum does have to be used immediately though once you feel the tingle and used frequently. If used immediately then the length of the cold sore is dramatically decreased and often the cold sore doesn’t erupt! They are so painful and ugly—it’s nice to have something that can help:)

    I bought this for my husband to use the next time he feels a cold sore coming and it works great! He said it went away in no time.

    Can’t say enough good things about this serum. If I start applying immediately and multiple times during the day, it drastically reduces the duration and symptoms of the cold sore. Abreva has never even come close!

    My only issue with it is that I can never get a small enough drop for what I need with the dropper.

    Absolutely amazing! I can’t even say how happy and relieved I am that I found this serum ! I struggle for years with cold sores and tried everything under the moon . I actually found one medicated chapstick which helped but only if I caught it right the second when it „ tickled „ and sometimes you just don’t notice or it comes while you are sleeping and at that point this chapstick was useless. I ordered the earthley serum with my first order on here and about a month I woke up with a big sore on my lip . I applied the oil and let me tell you I love the smell but that is just a plus on top . This stuff is magic. No pain and it started healing up after 2 days ! Never experienced anything like that before! Thank you earthley!!!!
    I love every single product we have and we have a lot ! Can’t wait to have all of them 🙂

    This serum is wonderful. I bought it to help the dry skin/scabs that accompany cold sores as they heal. The serum helped a lot with that as it soothed my skin very nicely. Then I noticed that it seemed to help a cold sore go away faster! So all around this is a wonderful product. I just purchased another bottle for a friend who has shingles hoping it will help her with the pain and itching.

    This stuff works! My 3 year old gets a cold sore anytime he gets sick & this heals it up within a few days. In the past he had a few outbreaks get way out of control, evening needing antibiotics to stop it. Ever since we got this his outbreaks stay under control! Such a relief.

  7. Becky Toth (verified owner)

    I love the cold sore serum!! I typically get one every couple months. I wanted to give this a try after trying si many things. Amazed at how quickly my cold sore resolved using this! Thank you!!

  8. Dana Hering (verified owner)

    BUY THIS! My husband and I both get cold sores. We apply at the first sign of a cold sore and its gone within a couple days. No more painful cracks in the corners of our mouth that keep us from being able to open them. We love it!

  9. Brandy Criswell (verified owner)

    I have suffered from cold sores my whole life. Trying tons of different over-the-counter remedies, balms, and nothing truly helped. A few years ago my mother suggested using tea tree oil and while that helped after getting the cold sore nothing helped as both prevention and remedy. Until this. I am so happy I found this product. I use this as part of my nightly skin care routine and in the past year have only had 1 or two cold sores that last for such a short period of time I barely remember them. Thank you so much for the natural safe product.

  10. Michele Hutchison (verified owner)

    I purchased this to help ward off cold sores I get due to stress. I use Abreva, but not sure how much that actually does and it’s expensive. I wanted a natural easy product. This is a great way to restore health to my skin when I feel anything coming on. Will definitely continue to use and recommend.

  11. Theresa Cobb (verified owner)

    I have struggled with cold sores for yearsssss…. and as you can imagine, I have tried every single thing out there on them! I can honestly say that this serum has been the ONLY product to actually help. I was skeptical at first because literally nothing else has helped.. so to say I was beyond ecstatic and grateful to see this product help, is an understatement! I keep stocked up, and suggest you do too!

  12. Aundrea Parker (verified owner)

    This is a game changer for cold sore sufferers!! I’ve suffered with cold sores my entire life! I’ve tried every product available for them. I had found others that I liked and thought worked well…until I used this! My son even had a weird thing on his lip that I was afraid was his first cold sore, but I’ll never know for sure bc it was gone overnight from one application!

  13. Erin (verified owner)

    Relief!! ⭐️⭐️⭐️⭐️⭐️
    Cold sore popped up Wednesday morning started using the serum and by Saturday morning it was 90% healed! I could not believe I was not going to have to suffer through a week + of healing time with a nasty sore on my lip.
    I have suffered from cold sores for decades so when I tell you I have tried everything to heal them I mean EVERYTHING.
    This is the best product I have ever used and will never use anything else!

  14. Lorie Baldridge

    I have been using this product for over a year now and I can honestly say it’s hands down the best product for any cold sores. I have tried so many products but nothing helped and a lot of them made my cold sores even worse. This serum is so fast acting and I feel like I can live a normal life now because of it ! I’m so thankful Earthley made something that actually works !

  15. Shelley (verified owner)

    My 10 year old & I get lots of cold sores. As soon as I feel something coming on, I apply this serum. I feel like it really stops the cold sore from spreading and getting larger. It defiantly takes away the itchiness & pain of the cold sore. The healing time is very quick. I love this stuff!

  16. Kim Becker (verified owner)

    This little brown bottle is a wonder!! I’m on an everyday prescription for cold sores but ran out. Of course a nasty old cold sore erupted within 24 hrs. I started applying this serum on it. In 2 days it was gone! I’ve never had anything work so fast and so well. I’m ditching the meds and keeping the serum..thank you for making such a great product.

  17. Gabrielle Shaffer (verified owner)

    I have had issues with cold sores for many years and I have tried many products and even saw a dermatologist for them. No matter what I used nothing helped me with them. This was until I found this product! Everytime I feel one coming on I put this on and feel instant relief I haven’t had a cold sore in a couple years since buying this! If I do get one this product makes them go away in just a couple days! I make sure this product is with me always!

  18. Adriana Mariscal (verified owner)

    Hands down the quickest remedy for a cold sore. I have been able to apply at 1st sight allowing my healing time to not only be quick but it honestly kept it from even getting large, ugly or painful. Miracle! I have never found something that worked this well and I unfortunately have dealt with many.

  19. Elana Murphy (verified owner)

    This is my go to wherever I get a cold sore, it really works!

  20. Lexxie Doster (verified owner)

    I love all of your products! Excited to try this. But is the bottle supposed to be half full? I’m a little concerned about tampering and whether I should use it. There were no signs of leaking in the packaging. It’s just half empty.
