Some people develop darker lips over time due to a range of medical and lifestyle factors.

Causes of dark lips

Darkening of the lips can be the result of hyperpigmentation. This is a typically harmless condition caused by an excess of melanin. Lip hyperpigmentation may be caused by:

• excessive exposure to the sun
• lack of hydration
• cigarette smoking
• allergic reactions to toothpaste, lipstick, etc.
• too much caffeine
• lip sucking

Most of these causes can be addressed by lifestyle changes, such as wearing sunscreen, limiting caffeine intake, or changing toothpaste brands.

The following can also lead to darker lips:

• chemotherapy
• anemia
• vitamin deficiency
• excessive fluoride use
