Fever blisters on lips are common, and some researchers estimate that the herpes simplex type 1 virus that causes it is present in between 60 and 90 percent of all people. For example, 67.4 percent in Belgium, 80.6 percent in the Czech Republic, 65 percent in the United States, and even higher in developing countries. If you struggle with it, you have a lot of company.
The virus is transmitted if people with the same virus kiss you, either when they have an active outbreak of fever blisters on their mouths, or if they have an asymptomatic episode of viral shedding (replication) which, as the name implies, has no symptoms. You can also get fever blisters on your lips from the herpes simplex type 2 virus if you have a microscopic cut on your lip and you perform oral sex on someone with the herpes simplex type 2 virus. Once you contract the virus, it is inactive almost all of the time, except during outbreaks of fever blisters and periods during which it asymptomatic reproduces to stay alive.
Do not confuse fever blisters and canker sores. The former are blisters, the latter are craters. The former more commonly occur outside your mouth, the latter always appear inside your mouth. You must understand the difference, because antiviral fever blister creams do not work for canker sores.
How to Prevent Fever Blisters on Lips
If you have contracted the herpes virus, you will almost certainly have some fever blister outbreaks. If you want to reduce the chance that the virus will become active, do all of the following:
- Moisturize your lips frequently, preferably with a natural substance that contains no chemicals to which you may be allergic. Dry, cracking lips is the largest welcome mat that you can lay down for fever blisters. My home-made moisturizer contains 40 percent rosehip oil, 40 percent shea butter, 10 percent lemon oil, and 10 percent tea tree oil. Both the tea tree and lemon oils are anti-viral, and the rosehip and shea are great sources of vitamins C and A, the two most important skin-healthy vitamins. Yours doesn’t have to be that elaborate, just ensure that it contains no chemical preservatives (natural organic are fine), artificial fragrances, and chemical sunscreens and moisturizers. Look out especially for butylated hydroxytoluene (BHT), octinoxate, oxybenzone, and parabens like methylparaben, butylparaben, ethylparaben, and propylparaben. All of these are known allergens.
- Strengthen your immune system by eating enough fruit and vegetables. It cannot get the necessary vitamins and minerals from grains, meat, and dairy, the prototypical North American diet.
- Protect your lips from the sun at all times.
- Refrain from biting your lips. Eat slowly and find a different outlet for your nerves.
- If you get frequent breakouts, a doctor may be willing to prescribe an oral anti-viral drug like valacyclovir or acyclovir, both of which have been proved to prevent most asymptomatic shedding and outbreaks of genital herpes. The researchers concluded that the same probably holds for herpes simplex type 1.
- I used a system called Ultimate Herpes Protocol that seems to have rendered the virus permanently inactive in my body.
How to Treat Fever Blisters on Your Lips
If an outbreak occurs, apply an anti-viral fever blister cream immediately, even before the blister appears. If a spot on your lip is sensitive, it might appear there. The earlier you apply it, the more likely it is that you can prevent the blister from developing. Herpeset contains many ingredients that can stop the virus from replicating and the blister from forming, but natural oils like lemon, tea tree and eucalyptus also work if you mix around 10 percent of it with 90 percent of any carrier oil, including coconut and olive.
