Photo Dynamic Therapy

Photodynamic Therapy may be recommended for patients with certain precancerous or cancerous skin conditions. It is suitable for treating actinic keratosis, superficial basal cell carcinoma, Bowen disease, and select cases of acne. PDT may also be considered when surgical removal is not preferred, especially in cosmetically sensitive areas. Your dermatologist will assess your skin and medical history to determine if PDT is a suitable treatment option.

PDT is a non-surgical dermatological treatment that uses a photosensitising agent, typically aminolevulinic acid (ALA), which is applied to the skin and absorbed by abnormal or damaged cells. After a few hours of incubation, the treated area is exposed to a specific light source (commonly blue or red light), activating the photosensitiser. This light activation destroys the targeted cells while sparing surrounding healthy tissue. The process is carefully monitored by your dermatologist to ensure precision and comfort.

Photodynamic Therapy is carried out at Integra Healthcare’s dermatology clinic in Grand Pavilion. The treatment area is equipped with state-of-the-art medical lighting systems and a calm, private environment designed to support safe and effective care.

PDT is available by appointment, scheduled based on your skin condition and the treatment plan outlined by your dermatologist. Most appointments are held during regular clinic hours, and pre-treatment instructions will be provided in advance.

PDT is most effective for:

• Actinic keratosis (scaly, sun-damaged skin)
• Superficial basal cell carcinoma (a type of non-melanoma skin cancer)
• Bowen disease (squamous cell carcinoma in situ)
• Acne and certain inflammatory lesions
• Some off-label uses including rosacea, pigmentation concerns, and photo-rejuvenation

Side effects of PDT are usually mild and temporary. Patients may experience stinging, tingling, or a sunburn-like sensation during or shortly after the procedure. Redness, swelling, peeling, or mild blistering of the treated area may occur for a few days. In rare cases, scarring or changes in pigmentation can result. Your dermatologist will provide detailed aftercare instructions, including guidance on sun exposure and the use of sunscreen to protect treated skin.

PDT offers an effective, non-invasive alternative to surgery or prolonged topical therapies. It is especially useful for treating multiple skin lesions in one session, or for areas where scarring from surgery may be more noticeable. It allows patients to avoid general anaesthesia and often involves minimal downtime.

After your PDT session, you will be given personalised aftercare instructions. Avoiding sun exposure is essential, as treated skin is temporarily light-sensitive. You will be advised to apply sunscreen regularly and may require follow-up appointments to monitor healing or assess the need for additional treatment sessions.
