Should I get a 2nd opinion about these freckles on my lips from another dermatologist? Last time they say it's just sun spots but the bottom one in particular still keeps me Does anyone know what this black mark on my lip is? Started last August so it's I've had it nearly a year, was living in Spain at the time for 6 months Labial melanotic macule Spotty lips. These are labial melanotic macules, kinda like freckles on the lips. They are mostly due to age and sun exposure, but sometimes they run in families and are associated with ORAL MELANOTIC MACULE (OMM) (Also called focal melanosis labial melanotic macule) A benign, localized, flat pigmented lesion of the oral mucosa Caused by a focal increase in melanin production Figure 1 from Oral melanotic macule a case report.
