PHOTODYNAMIC THERAPY (PDT)
What is PDT?
Photodynamic therapy (PDT) is a treatment option for pre-cancerous sun damage called actinic keratosis (AK) and superficial non-melanoma skin cancer (NMSC). It involves the use of a photosensitising agent and light to destroy abnormal skin cells.
​
Before undergoing PDT, a consultation is essential to determine if you are a suitable candidate for this treatment. A biopsy may be required to confirm the diagnosis of AK or NMSC. This most commonly involves taking a small shaving of a lesion, which will leave little to no scarring.
What to Expect during your PDT Treatment
The first step involves applying a topical photosensitising agent to the affected area, which is absorbed by pre-cancerous and cancerous skin cells.
Following a 60-minute absorption period, the area is exposed to a specific wavelength of light from our MediLUX LED device. This light triggers a chemical reaction that destroys the abnormal cells, while normal cells remain unaffected. Some heat, stinging, or discomfort may occur during the short treatment phase but typically subsides quickly
Aftercare
-
After the procedure, you may experience redness and swelling, which typically subsides by day 2-3, with redness and peeling resolving by day 7.
​
-
Avoid makeup for 5 days, and use soothing creams and SPF daily, such as AllMedic SPF 50+.
-
It's crucial to avoid sun exposure and bright light for 48 hours post-treatment, as your skin will be highly sensitive. Diligent sun protection, including protective clothing, hats, and broad-spectrum sunscreen, is essential, even indoors.
-
A follow-up appointment is usually scheduled 1 month after the PDT procedure to assess its effectiveness and check for recurrence. In some cases, a second treatment may be needed. Weekly photos of the treated area before your follow-up can help with assessment, though they are not essential.
Potential Side Effects
-
PDT is generally well tolerated, with swelling, redness, and discomfort subsiding within a few days. Skin redness may persist for weeks. Brown lesions may temporarily darken, and crusting usually resolves within 10 days, revealing normal skin.

-
Post-traumatic hyperpigmentation can occur, especially in those with darker skin types, but sun avoidance and SPF use can reduce this risk.
​​
-
Scarring and pigment loss are rare. Some may experience more intense inflammation with blistering, which can take weeks to heal. Some lesions may require a second treatment or alternative therapies.
