Does nail polish remover help stop cold sores?
Any alcohol base product such as perfume or nail polish remover will dry the effected area and if applied as soon as you feel a cold sore, but nail polish remover is pretty harsh on delicate skin. To treat cold sores you can either apply a cream you find in pharmacies. You can also dampen the spot with water and then apply baking soda and repeat. The most important application is the evening before bedtime as when sleeping you do not touch your lips and the product would have time to act.
