4. When to closely examine them
Even though most moles are harmless, it is still important to keep a close eye on them in case they change in a way that could mean something is wrong. You can use a mirror to check spots that are often in the sun, like those on your face, hands, legs, arms, chest, and back. You could also ask a friend or another person to help you.
If any of the following things happen to your skin, you should see a dermatologist:
– It looks different from the other moles on your body.
– It starts to show up after the age of 30.
– It makes you itch or bleed.
– Its color is not uniform.
– Its shape changes strangely or isn’t the same on both sides.
– It is bigger than a pencil eraser in diameter.
