How to get rid of Blisters
If the blisters have been a problem for you in the past, chances are they will return in the future. This is because herpes simplex 1, the virus that causes cold sores, lies in your cells, dormant. After certain triggers, the virus can re-activate, causing an outbreak of cold sores. There are several ways to get rid of these blood blisters. Some work better than others, but you’ll have to experiment to find a method that works best for you.
There are several over-the-counter medications you can use to get rid of them. Most of these are docosanol-based. If you can’t find a medication with docosanol, then tannic acid, zinc, phenol or lysine can serve as substitutes. All of these active ingredients have been proven to stop the herpes virus from developing fever blisters. Valtrex, Zoviraz and Famvir are common blister medications.
If chemical medications are not your thing, there are a variety of home remedies you can use. Tea tree oil is effective in healing and preventing blisters, as is Aloe Vera. Sage works as well, either in extract form or directly from the leaves. If using tea tree oil, sage, or Aloe, the proper way to apply it is to place a small dab of oil/gel directly on the affected area, and rub it in to your skin. Do this several times a day as needed, until your fever blisters heal up and go away.
Once you do have an outbreak, it’s important to keep it protected so it doesn’t get worse. Petroleum gel works well, helping speed up the healing process. It also protects the affected area from further bacterial infections. Also, keep in mind that the skin around your cold sores should be kept moist and healthy. You can put Vaseline or another moisturizer on the damaged area once a day. This will keep the skin moisturized and ensure that your sores don’t crack or start to bleed.
While aggressive treatment is recommended in some cases, it’s often better to just let nature run its course. Blisters usually disappear within 2 weeks, even if left alone. If you let your cold sores be and don’t bother them, they should be gone within 10-12 days. If more than 2 weeks have passed and the infection is not healing, you should go see a doctor. Also, using 1 or 2 treatments is good, but it’s never good to over-treat infections. Just because there are a lot of ways to treat fever blisters doesn’t mean you should use all of them at once! Try each different treatment at a different time, and see what works for you. Try to keep your skin healthy, and avoid foods that trigger outbreaks. Remember, the best treatment is always prevention, so if you can, avoid triggers that are proven to lead to outbreaks. Fatty, acidic and salty foods are linked to cold sores, as are stress, fatigue, and exposure to sunlight (which is why using SPF 15+ is recommended for people affected by cold sores).
