Can I use Prevasore regularly / long-term?
Yes, Prevasore is suitable for regular long-term (every day) lip care to help treat and prevent chapped lips and the occurrence of cold sores. It can also be used on an occasional basis, as and when a cold sore occurs. However, regular everyday use of an effective lip care product should help maintain healthy lips which has been seen to reduce repeated cold sore outbreaks.

Can I use Prevasore on a cold sore scab?
Yes. Prevasore is suitable to help with healing cold sore scabs.

It is best to start using Prevasore as soon as the first signs of a cold sore develop, and to continue using it, as often as necessary, until the cold sore is completely healed.

Regular everyday use of Prevasore after a cold sore episode has cleared can help to keep your lips in good condition, and reduce further outbreaks.

Are there any lip problems for which Prevasore is unsuitable?
Prevasore is for sore and cracked (chapped) lips and cold sores only. Do not use it for any skin infection other than a cold sore, and if the problem hasn’t healed completely within about two weeks talk to a doctor, nurse or pharmacist to check the diagnosis.

How does Prevasore help cold sores?

Prevasore can help with cold sores in three ways:

Helping to prevent cold sores:
It is known that chapped lips can be a trigger for cold sores and that the frequency of cold sore outbreaks is reduced by keeping the lips soft and moisturised, maintaining the natural barrier function of the skin. 

Using Prevasore regularly can help to keep your lips in good condition. The emollient (moisturising ingredient) and the humectant (moisture retaining ingredient) help to balance the moisture levels within the skin to maintain the natural suppleness.

Relieving the symptoms of a cold sore:
Using Prevasore at the first signs of a cold sore, when you sense the characteristic local tingling / itching / burning can assist the natural healing process. Prevasore’s unique gel formulation is designed to allow easy, gentle application of its moisturising and lubricating protective layer over the tender area of the cold sore.

Helping to heal a cold sore:
Using Prevasore as soon as a cold sore starts can help with the normal healing process, and can help protect against further aggravation by the external environment or a secondary infection.

Prevasore works by forming a moisturising and lubricating layer which may help to reduce the overall time it takes for the cold sore to resolve. 

If a cold sore episode has not healed completely within about two weeks, or if you regularly suffer frequent severe cold sores, it is advisable to talk to a doctor, nurse or pharmacist.

Can I use Prevasore whilst pregnant or breast-feeding?
This product can be used during pregnancy and by breast-feeding mothers. The ingredients have been in widespread use in this and similar preparations for many years, without reports of problems. However, safety trials have not been conducted.
