Will hemangioma recur after laser treatment?

In general, whether a vascular tumor will recur after laser treatment depends on a comprehensive assessment of various factors, including the type, size, location, treatment technique, and individual patient differences. A detailed analysis is as follows:

If the vascular tumor is superficial, small in size, and located in the upper layers of the skin, laser energy can fully target the lesion, thoroughly destroy the abnormal blood vessels, and—combined with strong inherent recovery ability in the patient—result in a low probability of recurrence. With standardized treatment and proper postoperative care, most such cases achieve favorable outcomes and rarely experience regrowth of the lesion.

However, if the vascular tumor is deep-seated, large in size, or located in an anatomically challenging area, the laser may fail to fully penetrate and eliminate the deeper abnormal vessels. In addition, if the treatment technique does not precisely control the energy dosage, the risk of recurrence after surgery increases. Some patients, due to individual differences such as stronger blood vessel regeneration capacity, may also experience re-emergence of the lesion.

After laser treatment, it is important to keep the treated area clean and dry, avoiding friction or scratching that could lead to infection. Repair ointments should be applied exactly as prescribed by the physician to promote skin healing. Exposure to direct sunlight should be avoided for a period after treatment to prevent hyperpigmentation or skin damage. Regular follow-up visits are essential; if abnormal redness, swelling, or elevation appears at the treatment site, prompt medical evaluation is necessary. Patients should not self-treat any skin issues arising after surgery, but instead seek care and further interventions under the guidance of a physician.
