Laser treatment is often used when other treatment options for removing a wart have not been successful.
For example, laser treatment is used for
- particularly severe cases of warts,
- deep-seated warts, particularly plantar warts, and
- protracted cases where no success has been achieved.
Laser wart removal is the most expensive option for wart removal. The results of laser treatment are not always permanent; sometimes a new wart grows back afterward. This is especially true if the wart had already spread deep into the inner layers of the skin. In such cases, another laser treatment is necessary to remove the wart.
To prevent new warts from appearing, early laser treatment is recommended. This prevents the wart from growing in too deeply.
The human skin is composed of nearly seventy percent water. This allows the doctor to use laser treatment to remove layers of skin without damaging the underlying tissue.
For children, you should consider an alternative method of wart removal. Children’s skin is still very thin and sensitive. In such cases, cryotherapy is preferable to laser treatment.
Laser treatment takes place in a hospital. It is performed under general or local anesthesia, as the procedure would otherwise be very painful.
The doctor removes the problematic skin growths layer by layer with the laser. Finally, the wound is suctioned to remove all wound secretions.
In the case of a deeply ingrown plantar wart, the callus must be removed deeply, sometimes extending into the dermis.

General Aftercare Following Laser Wart Treatment
Laser treatment creates an open wound that may bleed and ooze. The wounds can bleed for up to two days, especially in the case of deep plantar warts. Severe to very severe pain is also to be expected after the treatment.
To prevent infection, it is important to care for the wound properly. The wound is covered with a breathable film dressing. This helps prevent a scab from forming over the wound. The dressing is transparent and is usually made of polyurethane.
You should change this dressing once or twice a day after the laser treatment until there is no longer any wound discharge. This can take three to six days.
However, there are also areas of skin where a film dressing cannot be applied. In this case, it is best to use an ointment containing the active ingredient dexpanthenol. When applying the ointment, be careful not to damage the newly formed scab. It provides very good protection against infection.
The treated areas of skin are usually still reddened after laser treatment. After a laser treatment, temporary hyperpigmentation may occur at the treated site. However, this usually fades after four to six months. You can apply a lightening cream as a complementary measure, but this is not necessary.
Your body’s immune system continues to play a major role even after laser treatment. Support your immune system by
- a healthy diet,
- getting enough sleep, and
- avoiding constant stress.
A healthy immune system makes it harder for wart-causing pathogens to establish themselves in the body and cause a wart to form.
Once the healing process is complete, a more or less visible scar will remain.
Aftercare for Warts on the Feet
Elevating your feet supports the healing process. Breathable cotton socks and stockings facilitate wound healing after laser treatment. Wear them over the bandage.
You should not expose the wound to UV light (e.g., sunlight) during the healing process. Even with a securely fitted bandage, you should avoid walking barefoot, as germs and bacteria could enter the wound.
Once the wound has healed, you can resume physical activity as soon as the pain has subsided and you no longer need a bandage. When walking barefoot—for example, in a swimming pool or sauna—always wear flip-flops to avoid the risk of a new infection.
Pus may also form after laser treatment to remove warts. The edges of the wound may also swell. If you notice such symptoms on the sole of your foot after laser treatment, you should see a doctor, who will take appropriate measures to treat the infection.
A whitish crust on the wound after laser treatment, on the other hand, is generally considered harmless. Treatment is not necessary in this case.
If you follow all precautions after laser treatment, the wound will generally heal well.
To prevent further warts, you should always wear flip-flops in public areas and support your immune system.
