Photodynamic therapy (PDT) is an FDA-approved treatment specifically for actinic keratoses (AKs), precancerous skin growths caused by sun damage.
Photodynamic Therapy: A Closer Look
PDT involves applying a topical photosensitizing agent to the affected skin, followed by exposure to a specific wavelength of light. This light activates the agent, destroying the sun-damaged cells.
Why PDT is Used for Sun-Damaged Skin:
- Targets Precancerous Cells: AKs are considered precursors to skin cancer, and PDT effectively eliminates these abnormal cells.
- Non-Invasive: PDT is a non-surgical option, making it a less invasive alternative to other treatments.
- FDA-Approved: The FDA has approved PDT for the treatment of AKs, ensuring its safety and efficacy.
Considerations:
While PDT is effective for AKs, it's essential to consult with a dermatologist to determine if it's the appropriate treatment for your specific condition and skin type. They can assess the extent of sun damage and recommend the most suitable approach.
