What Are Moles?

Moles can be expected to lighten or darken over time.

For children and teenagers, moles grow as the person grows.

Most adults have 10 to 40 common moles and may continue developing moles until age 40.

Atypical moles(also calleddysplastic nevi) are moles that should be watched for changes.

While they are not cancerous themselves, melanoma can grow in atypical moles.

Spitz nevi may bleed or ooze.

What Are Freckles?

Freckles are harmless skin spots of increased skin pigment (melanin).

This then shows up as freckles.

you’re free to think of freckles as your skins way of protecting you from sun damage.

However, they do not replace sunscreen or other sun protection.

They also differ in when and where they show up and if and how they fade over time.

The main way to tell the difference between a freckle and a mole is to note their appearance.

Moles are usually raised and dome-shaped,whereas freckles are usually flat.

Freckles are completely harmless, whereas some moles can be at risk of skin cancer growth.

Sometimes, people use the term “beauty marks for skin features like freckles and moles.

A beauty mark is more of a cultural term.

It refers to a dark spot on the face considered to be attractive.

However, beauty marks are usually just a mole or a freckle.
