Laser Treatment for Warts

A laser can heat or vaporise selected wart tissue. Some approaches target the blood supply that supports the wart, while others remove the surface lesion. The treated area may be sore, swollen, red or covered by a crust during healing. The result depends on the wart’s thickness and location; a wart on a sole may behave differently from one on a finger or face.

Warts are linked to a virus in the skin, so removing visible tissue does not always prevent a new wart from appearing. Avoid sharing towels, razors or nail tools, and do not cut or pick the lesion. Covering a wart can reduce contact with other skin while it is being treated.

A clinician may examine the lesion closely before choosing laser, particularly if it is bleeding, oddly coloured or not behaving like a typical wart. Tell them about medicines, poor wound healing, immune problems and previous treatments. Follow wound-care instructions, keep the area clean and avoid soaking or friction until advised. Do not apply home acids or other products to freshly treated skin unless specifically instructed. Other options include cryotherapy, electrosurgery or prescription treatment such as imiquimod in selected cases.

Call the treating clinic if pain, redness or swelling is worsening rather than easing, or if the wound develops pus, spreading warmth or an unpleasant smell. Seek urgent help for heavy bleeding that does not stop with firm pressure. Arrange assessment for a lesion that changes quickly, repeatedly bleeds, becomes very painful or does not heal, because not every rough growth is a wart.

Ask how the diagnosis was made, why laser is being suggested, what depth will be treated, and what the wound may look like during healing. Discuss the risk of scarring or pigment change, infection prevention, pain relief and the plan if the wart returns.
