Cold sores, also known as fever blisters, are caused by the Herpes Simplex Virus (HSV-1). They appear as small blisters on the lips or around the mouth, which then rupture and form scabs over the course of a few days. If left untreated, they can take up to three weeks to heal completely.

HSV-1 is highly contagious and spreads through close contact with an infected person. After the initial infection, the virus remains dormant in the body and can reactivate, causing outbreaks. The frequency and severity of these flare-ups vary among individuals.

Triggers for outbreaks include stress, illness, injury, weakened immune systems, and excessive sunlight exposure. An imbalance of certain amino acids, particularly high arginine and low lysine levels, can also contribute to outbreaks. Diet plays a role as well—acidic foods, sugary snacks, and beverages like orange juice may trigger cold sores, while lysine-rich foods like fruits, vegetables, and dairy can help prevent them.

Additionally, positive ions, such as those found after a thunderstorm, may exacerbate the virus. Some people have found relief using air purifiers with negative ion generators.

When a cold sore appears, the virus is protected by a lipid envelope, making treatment difficult. Robinson’s Remedies Lip Repair is designed to penetrate this barrier and provide rapid relief. Regular use of the product can also help create an environment less conducive to cold sore development.

While HSV-1 cannot be cured, outbreaks can be managed by reducing stress, identifying triggers, and acting quickly at the onset of symptoms. By combining these strategies, living with HSV-1 can be more manageable.
