Cold sore patches are clear hydrocolloid patches that cover and protect a cold sore.
How it works
They create a moist healing environment, help reduce scabbing and lower the risk of spreading the virus.
How to use it
Apply a fresh patch to clean, dry skin as soon as you notice a cold sore, and replace it when it falls off. Use until the sore heals. Always read the instructions before use.
Before you use it
Do not use inside the mouth. Wash your hands after touching a cold sore.
Possible side effects
Skin irritation is rare.
