Home Treatments for Cold Sore

Sunscreen

Sunscreen helps protect the lips when the cold sore is healing, and it also reduces the possibility of future outbreaks when worn every day on the lips. Generally, the lips are very susceptible to the sun’s radiation as the rest of the body, making them vulnerable to skin cancer. Hence, sunscreen helps in filtering harmful UVB rays and gives protection from related skin problems.

Wearing sunscreen on the lips may also help maintain hydrated lips. It helps against the environmental effects of the sun and wind and prevents dryness.

When sunscreens are used on the entire skin, they may help prevent premature aging like wrinkles and leathery skin. Note that sunscreens may come with specific side effects. It’s advisable to stop using sunscreen that causes redness or irritation.
