Blood dried Blister on lip
After 1 week of having cold sore on lip, I accidentally scratched the skin when I tried to wipe my mouth. Few days after that my cold sore looks like dried blood blister. It looks unsightly and it kind of scares me. Should I let this blister alone? I tried putting aloe Vera.

Ugh, cold sores are miserable. When you have an outbreak do you put anything on such as Abreva? That ointment helps to control the lesion from getting any larger along with keeping it from developing a hard scab. I’m wondering if that’s what has happened in this case after the scratch.
What type of aloe vera are you applying? Is it in an ointment? If you have any over the counter medication like Abreva, or even something like Vaseline or Carmex to keep it moist you might try one of those. You might even try applying an antibiotic cream such as you’d use on a scratch. If it doesn’t go away in a few more days or you see it getting worse then you might want to have it checked out at a clinic. Keeping it moist will reduce the chance of scarring.
Is it very sore when you touch it? Do you feel there’s any swelling under the dried area? Is it dry or do you think there is pus inside?
For the first few days I am afraid I didn't put anything. I didn't know exactly what it was appearing on my lip.
After few days I understood it was a cold sore.
I got myself today a Zovirax cream.
It doesn't look swollen.
It looks brownish, looks like it's empty inside, it doesn't feel anything when I softly touch it but around that blister is bit red from the scratch of the new skin underneath.
I don't know if I should apply that Zovirax cream on my dry blister I feel like it will fall if I touch it, or let it go by itself.
Should I try taking a picture?
It actually sounds like it’s just a scab waiting to fall off at this point. Hang onto that zorivax cream for the future. If you get that weird feeling on your lip again or a sign of eruption you’ll have that cream ready to go.
But for now, the scab might let go by itself. You can try putting a little Vaseline petroleum jelly on it. That way the scab will soften and also it will keep the area protected while continuing to heal. But from what you’re saying it really does seem like it’s pretty well healed already and just waiting for that scab to drop off.
Would you feel better sending a picture? It’s fine if you’d like to.
Hi sorry I just saw the reply, I put last night the zorivax cream, I'll add a photo. The white part is the dried cream from last night on my blister.
Sorry for unsightly photos.
No worries about the photos! That helped quite a bit.
I’m fairly sure it’s just the outside scab waiting to drop off! It looks like it’s ready any time. Remember when you were a kid and probably skinned your knee? It took a while for all of the scab to release? I’m thinking that’s what this looks like.
The cream won’t do any more for it. It looks dry all the way through and should come off by itself. You could try a warm wet washcloth for a few minutes and then it might just lift right off.
The skin will be pink underneath so avoid sunlight and keep a small wipe of petroleum jelly on it or lip balm for a few days.
For future reference, when you have an active cold sore, it is caused by a virus and can be easily transmitted via sharing glasses, kissing, or touching the sore and then touching something else.
Was this your first one?
Thank you so much!
Yes it was, and I didn't know how to deal with it, and after I scratched the cold sore by accident this dry blister happened and it freaked me out. I don't feel itchiness or anything. Feels weird when touching it softly when washing my face, like a dry skin hanging on my lip.
But yeah, I will just leave it as it is until it comes off.
Thank you for your help and knowledge!
It’s my pleasure. I’m glad I could help you out and reduce the anxiety. 😊We’re our own worst enemies, I swear.
Hi @nejex! Thought I’d check in with you to see how your lip is healing? All good now, I hope??
