What should you know about cryotherapy for actinic cheilitis?

Actinic cheilitis is sun-related damage that commonly affects the lower lip. It may cause persistent dryness, roughness, scaling, blurred lip borders, color change, tenderness, or cracking. Cryotherapy freezes selected abnormal surface tissue, after which the lip may swell, crust, or feel sore while it heals. The treatment choice depends on how widespread or thick the change is and whether any area needs sampling.

A persistent sore, firm thickening, bleeding spot, ulcer, or change that does not heal deserves review rather than repeated freezing. Sun protection remains relevant because ongoing exposure can contribute to further [Sun-Damaged Skin](/conditions/photoaging/).

See a dermatologist or other qualified clinician for examination before treatment. Ask how the lip will be numbed, protected, and cared for afterward; whether a biopsy is needed; and how follow-up will check the treated area. Depending on the findings, options may include [CO2 Laser Resurfacing](/treatments/laser-and-energy/co2-laser-resurfacing/), [Photodynamic Therapy](/treatments/laser-and-energy/photodynamic-therapy/), or [Topical 5-Fluorouracil](/treatments/medical-dermatology/topical-5-fluorouracil/). Use lip sun protection and do not pick crusts.

Contact the treating clinician for increasing pain, spreading redness, pus, fever, heavy bleeding, or healing that is not progressing. Arrange prompt review if a thickened, ulcerated, or bleeding area persists or returns after treatment.

Does this area need a biopsy before freezing? Which treatment fits the extent and thickness of the lip change? What healing signs are expected, and how will recurrence or a new lesion be checked?
