    This product is incredible. My oldest always gets really bad cold sores. They become so big and hurt so badly. I bought this serum and didn’t get to use it for months. Then last week he woke with the starting of a cold sore. We immediately put the serum on and he said it made the sore area more comfortable. We applied it a few times a day for four days and his cold sore never grew. It was amazing. It stopped it in its tracks. He told me I had to write a review because he wanted others to know how good this serum is. It numbed the area a bit and prevented it from getting big and painful. Wow! A staple in our medicine cabinet.

    I’ve been getting cold sores my whole life and have legit given up on trying to find a “miracle cure” for them. I accepted that as soon as I get one, I can only do so much to help. So even though I love all Earthley products, I was still hesitant to buy this, scared to be let down once again. I finally had to use it yesterday for the 1st time and it actually worked! Like you can barely tell today that I had one starting yesterday. My mind is blown! I finally have my MIRACLE CURE FOR COLD SORES! Don’t hesitate on buying this!

    Here’s what I did: I put ice on the coldsore for probably an hour straight as soon as I woke up with the tingling in my lip. Then I took a needle and popped every little bubble I could find. Then put hydrogen peroxide on the cold sore area to clean it. Then I put the Earthley serum on. Within an hour I cold tell it was working. Typically my lip starts to swell up again no matter what I put on it. (I know everyone says to not pop it, but in my years of experience, it always goes away faster if I pop it right away rather than letting it go. Just my opinion though.) Buy this product!!!

    I have dealt with cold sores for over 35 years. I have tried literally everything and I can honestly say this stuff works! 2-4 days and it is completely gone. It did dry my lip out a lot so used a lip balm often. But I don’t care. I’d rather have a dry lip than a cold sore!

    My husband get cold sores all the time (stress related) and normally he takes pills to get rid of them, but when I saw this product of yours, I had to give it a try. Two days ago my husband told me that he feels the sore coming up; I jumped up, ran to the cabinet and gave him the serum bottle (he was skeptical) but two days later it is barely visible and believe me he gets them bad! This stuff seems to work! I am truly excited.

    BUY IT!!
    My poor boy (6 years old) suffers from cold sores about twice a year. They are always so swollen and painful and sometimes he will have two spots. It usually takes acyclovir and 7-9 days to fully heal. Day TWO with this and it’s already starting to scab over and never really had much swelling. I also didn’t have to give him acyclovir this round (which i always hated having to do to him because it can be hard on your kidneys)
    Loooove Earthley products!
