Cold sores are a form of oral herpes caused by a strain of the herpes virus known as HSV-1. Some people get the virus as a child while others don’t experience it until their later adulthood years. The virus is transmitted in a number of different ways including the exchange of saliva (kissing), sharing a drink with an infected individual, using a towel that an infected person rubbed their face on, and more.[1]

It may be hard to believe, but more than half of all people are carriers of the disease. Only about 10% or so actually develop contagious sores from it, though. Nevertheless, the individuals that do develop sores go through a lot of pain and embarrassment. The symptoms of cold sores are easy to identify, but repeat sufferers know that they are often itchy, cause a burning feeling, and aren’t easy on the eyes.

The good news, however, is that cold sores are treatable. There are tons of different products available that can help provide fast relief of the symptoms and use the best over the counter cold sore medicine to help speed up the healing process. One such product is the Herpecin-L Lip Balm Stick. Below, we’re going to talk more about this special lip balm and explain why it’s a great option for people suffering from cold sores.

Equipped with powerful ingredients that work well to stop cold sores fast, Herpecin-L is a specially-formulated lip balm that treats cold sores, provides relief from common symptoms of fever blisters, has built-in sunscreen to prevent sunburn, and gives moisture and nutrients necessary to heal the lips as quickly as possible.

This is a unique, pharmacist-recommended product that does a superb job of providing instant relief from burning, itching, and oozing, while at the same time injecting the lips with medication that speeds up recovery so you don’t have to suffer from cold sores for a week or longer. This product can be used as needed to prevent chapped lips, too. It works awesome as a preventative treatment as well.

A product that we like is by Campho-Phenique, which is excellent for treating the early stages of cold sores, including the more unpleasant symptoms. You should read more about Campho-Phenique cold sore treatment in this review.

How Fast Does It Work?

Whenever you get a flare-up of cold sores the last thing you want is to use a product that requires you to wait for it to start working. Herpecin-L begins working the second you rub the balm on your lips. The moment it touches your lips it starts soothing and healing. This means fast relief of the itching and burning, plus it instantly begins penetrating the skin, providing a dose of powerful medication that will reduce the healing time greatly.

How to Use It

This product works similarly to other lip balms. You simply need to apply it to your lips. The manufacturer recommends applying the balm to the affected areas the moment you feel a cold sore coming on (that tingling feeling) as well as 15 mins before going out in the sun.

To ensure comfort, you’ll want to gently rub the stick over your lips. Make sure you cover the entire affected area, but be easy while doing it so you don’t cause further irritation at the location of the sores. The balm can be reapplied as often as you like to relieve the symptoms.

  • NOTE: This product is not necessarily intended for children under the age of 12. Please speak with your physician or pediatrician before using any health products on your child to make sure it is 100% safe. Children’s needs are different from adults and they may react differently to the balm than someone 13 or older.
