Everyone has had blisters at one time or another. You can probably remember what they look like, but let's talk about that in case you don't.
The area where blisters usually form is usually red and raised. Then a small bubble forms which is usually filled with liquid. After some time, that liquid is going to discharge and the blister is going to scab. Usually, after the scab is gone, you'll see no scars or anything that will remind you of the blister.
Now, of course, different blisters look a little differently. For instance, when you have a cold sore, it may seem that you get one big blister, but in fact, that big bump that usually burns and itches is formed by lots of tiny little bubbles packed close to each other.
Again, if you have a blister that comes from getting burnt, you'll see that it's a little bigger, more white and a lot firmer than a regular blister. All of the blisters usually have some kind of a watery looking substance inside them that will sooner or later discharge, unless it gets absorbed.
Most of the small blisters don't leave scars, but obviously, if you mess with it too much and try to pop it or pick it, you might end up with a little scarry souvenir that will not go away on it's own.
Most scars that come from blisters do pale away, but they never actually disappear. The reason you don't see them after a few months is that they absorb a little pigment and look a lot like your skin.
How do you treat blisters?
Well, again, it depends on the blister itself. Some of them you can treat with toothpaste (the cold sore blisters) and other blisters will require professional care (for instance the ones you get after you spill water on yourself).
It's generally a good idea not to cover your blisters with anything. The more air they get, the easier they will heal. Some of the less dangerous ones you can treat with mixtures that are readily available at a local drug store or with band aids that will help them to heal.
Whatever you do, if your blister looks a bit more scarry than what you usually see (like when it's super big for some reason) make sure that someone takes a serious look at it.
Again, if you don't take care of your blisters properly, you'll get scars and you'll have to deal with them for the rest of your life. Not worth it, if you ask me.
Blisters are not very fun to deal with. Generally speaking, if you wait them out, you'll be just fine, but if you pop them, then you can expect scars. Use the tips from this article to learn how to spot and treat a blister.
