Find a Dermatologist

You can search by location, condition, and procedure to find the dermatologist that’s right for you.

Why choose a board-certified dermatologist?

When it comes to treating the skin, plenty of people say they have expertise. Only a board-certified dermatologist has these credentials.

Can you stop cold sore before starts?

The key to stopping a cold sore quickly is to treat it the moment you notice symptoms. While it's rarely possible to completely avoid a cold sore, treating it before it develops into a larger sore is a good way to limit its development and deal with a smaller, less obvious sore.

How do you stop a cold sore from forming fast?

There are antiviral drugs that can help cold sores heal faster, including acyclovir, valacyclovir, famciclovir and penciclovir. If you're having frequent outbreaks or experiencing some of the serious side effects of having a cold sore, your doctor may consider prescribing antiviral medication.
