Description

Acquired moles are the common moles that develop after birth, typically appearing during childhood and continuing to form into a person's 30s or 40s. They're usually small, round, and evenly colored, and most people accumulate a new mole here and there throughout life.

Causes

A benign, localized overgrowth of melanocytes, strongly influenced by cumulative sun exposure over time.

Prevention

Daily sun protection can meaningfully reduce how many new moles form over a lifetime.

Treatment Options

No treatment is needed for typical acquired moles; removal is available for cosmetic reasons or if a mole shows any concerning changes.

Myths vs. Facts

Myth: Moles that appear later in life are more dangerous. Fact: New moles can appear at any age; what matters most is whether a mole is changing, not simply when it appeared.

When to See a Dermatologist

For a routine skin check, or if a new or existing mole starts changing.
