An advanced and effective treatment for precancerous lesions and superficial, early-stage cancerous lesions
Photodynamic therapy (PDT) is an advanced, non-invasive medical treatment based on applying an active substance to the skin followed by exposure to red light of a specific wavelength. The combination of the substance and the light causes targeted destruction of damaged cells, while preserving the surrounding healthy tissue as much as possible.
At On.Top we offer PDT with close medical support and excellent aesthetic results.
Similar to applying 5-FU cream (Efudex cream), photodynamic therapy makes it possible to treat a relatively large area of skin non-invasively, and even to heal precancerous and early cancerous lesions without a scalpel and usually without scars or marks. Unlike 5-FU cream, photodynamic therapy involves a short recovery period (down time) of only a few days, so it is also suitable for patients with a busy lifestyle who cannot afford to walk around with red skin for two to three months after treatment.
The effectiveness of photodynamic therapy varies depending on the lesion, and is generally slightly lower than that of treatment with 5-FU cream, but it is a good compromise between treatment effectiveness, side effects and the ability to stay with the treatment.
Photodynamic therapy is recognized by some insurance companies as a “surgery-alternative treatment”, so partial reimbursement of the cost can be obtained, depending on the policy.
Photodynamic therapy (PDT) is a non-invasive procedure that combines applying an active substance and exposure to red light, for targeted destruction of damaged cells while preserving healthy tissue.
The treatment includes three stages:
The treatment usually takes 60-90 minutes.
During the exposure to light, some patients report a sensation of warmth, burning or tingling.
If needed, the area can be cooled during treatment to significantly ease the sensation.
After treatment there may be redness, swelling or gentle peeling, which are transient effects indicating a normal therapeutic response.
For 48-72 hours after treatment, avoid sun exposure, even indirect, and be sure to use high-protection sunscreen. Redness and peeling may last for several days.
In most cases one or two sessions are needed, depending on the physician’s assessment.
