Cold sores are blisters that are usually found around the mouth and lips. These blisters are caused by the herpes virus, and can last anywhere up to two weeks. They are contagious and can be passed on by skin contact, and can be caused by both HSV-1 and HSV-2.
The most common kind of cold sore is caused by the HSV-1, a variety of the herpes simplex virus that prefers to grow around the mouth. However, if a person has oral sex with HSV-2, they can suffer from cold sores made of this particular kind of the virus.
The HSV-1 ‘cold sore virus’ has a number of triggers, and it depends on the person. Some of these triggers include being out in the cold, having chapped lips or being stressed and tired. They will occur a few times a year and will clear up between one and two weeks.
There are lots of antiviral creams available over the counter that can help get rid of the cold sore, but many people opt for home remedies instead. Rather than covering your skin in manmade chemicals, try some of these home remedies that can be better for your skin, or just more convenient.
1. Cover it up
The first thing you need to do with a cold sore is cover it up. As much s it is a blister, it is also an exposed wound, meaning that you should take every step you can to avoid secondary infection. The best way to cover it up would be to use petroleum jelly. Rub the jelly over the affected around and apply a few times a day, with clean fingers, and you can stop bacteria infecting the broken skin.
You can also use anesthetic ointment that contains benzocaine, which numbs the area and gets rid of some of the pain as well as stopping secondary infection from bacteria or even another virus.
You should be aware, however, that covering up a cold sore with makeup may just make it worse, so be sure to use only petroleum jelly or ointment.
