I Have a Dark Spot on My Lip: What Should I Know?

A spot may follow a healed blister, bite, burn, or lip product reaction; this is called post-inflammatory pigmentation. Sun-related marks and melasma can also affect facial skin. A fungal condition such as tinea versicolor is less typical on the lip but may be considered when there are scaly patches elsewhere. Colour, texture, timing, and whether the mark is on the lip surface or nearby skin help guide assessment. A photograph can help you notice change over time.

See [Dark Patches On Skin](/symptoms/dark-patches-on-skin/) for related pigment concerns.

Use a lip product with sun protection when outdoors, avoid licking or biting the area, and stop any new product that burns or irritates. Do not apply strong bleaching agents, acids, or home remedies to the lip. Keep a simple dated photograph in similar lighting if you are monitoring a stable spot.

Once the cause is clear, a clinician may discuss [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/), [Skin Brightening Treatment](/treatments/aesthetic-procedures/skin-brightening-treatment/), or [Picosecond Laser Treatment](/treatments/laser-and-energy/picosecond-laser-treatment/). These are not suitable for every lip lesion.

Arrange prompt assessment if the mark is growing, changing colour or outline, bleeding, crusting, painful, persistently itchy, ulcerated, or associated with a lump. Seek urgent help for rapidly spreading swelling or trouble breathing. A stable spot can still be checked routinely, especially if you cannot explain when it began.

Ask whether the spot is on the lip mucosa or surrounding skin, whether it needs dermoscopy or another test, which products to avoid, and when pigment treatment would be safe if no concerning cause is found.
