Laser Treatment for a Venous Lake on the Lip

A venous lake is a compressible collection of widened small veins that commonly appears as a blue, purple or dark-red spot on a lip. It may look darker when the lip is dependent or after pressure, and it can refill after being emptied. Laser energy can be absorbed by blood pigment, heating the abnormal vessels so the body can gradually clear treated tissue. The lip may be swollen, tender or crusted for a short period after treatment.

The appearance of a vascular spot can overlap with other lesions. Examination matters before a cosmetic procedure, especially if the mark is new, changing, bleeding without provocation or repeatedly ulcerating.

Have the spot assessed by a dermatologist or suitably trained clinician. Ask which laser is being considered, whether a test area is appropriate, how the lip will be protected, and what healing should look like. Keep the area clean, avoid picking crusts and use only recommended ointments while it heals. Protect the lip from strong sun after treatment. Electrosurgery is another treatment option that may be discussed when laser is unsuitable or unavailable.

Contact the treating clinician if swelling interferes with eating or breathing, pain is escalating, the treated area becomes hot and increasingly red, or discharge develops. Seek urgent care for sudden breathing difficulty or rapidly increasing swelling. Arrange prompt assessment for a spot that changes in colour or shape, bleeds repeatedly, becomes persistently sore or fails to heal as expected.

Ask how confident the clinician is in the diagnosis, what result is realistic, whether more than one session may be needed, and which temporary effects are expected. Discuss scarring, pigment alteration, recurrence, pain control and whether [Electrosurgery](/treatments/surgical-dermatology/electrosurgery/) is a better fit for your lesion.
