Fatigue and illness

There is a greater risk of the cold sore virus being activated when you are tired and your immune system is weakened. Be particularly careful in colder seasons, when many people around you are experiencing a cold or flu.

Maintaining a strong immune system throughout the year can decrease your risk of getting a cold sore. Ensure your vitamin intake is sufficient and avoid close contact with sick people. If you are stocking up on cold and flu treatments at your pharmacy, it’s a good idea to have some Vectavir Cold Sore Cream on hand too.



Ever wondered why cold sores appear at the worst possible moments, such as before an important meeting or event? Stress puts pressure on the immune system and this can trigger a cold sore.

Unfortunately, avoiding stressful situations entirely is not always possible. Try reducing stress by taking time for yourself, relaxing and ensuring you get enough sleep. And remember to have Vectavir Cold Sore Cream ready, just in case.



Ultraviolet (UV) light not only damages the skin cells and causes premature aging, but can also activate the cold sore virus. Take extra care when you are exposed to the sun and always wear sunscreen and lip balm with a high SPF.

You may be particularly prone to cold sores on summer holidays and ski vacations where sun exposure is high. Remember to pack your Vectavir Cold Sore Cream when you travel so you don’t get caught out.


Winter and wind

Cold temperatures and wind can dry out your skin and lips and make them more susceptible to cold sores. Plus, less vitamin D in the body and a weakened immune system can increase your risk of developing a cold sore during the colder months.

Try to keep yourself warm in cold weather and use lip balm to keep your lips hydrated.



Hormonal changes, like those that occur during monthly menstrual cycles, may be another trigger of cold sores. If you notice that you have a tendency to get cold sores during your menstrual cycle, keep Vectavir Cold Sore Cream on hand during these days for immediate treatment should symptoms arise.


Other people infected with cold sores

Avoid close contact with strangers or with people infected with cold sores and try to avoid sharing utensils with others. Remember that the cold sore virus is most contagious during the blistering and crusting stages.
