Photodynamic therapy

This is used to treat skin cancer, and skin damaged by excessive sun exposure which is at high risk of becoming cancerous. It works by directing a beam of light onto a mole, lesion or affected area of skin which destroys cancerous cells within. It has a lower risk of scarring compared with surgery.

It is used to treat Bowen’s disease, basal cell carcinoma and solar keratosis (pre-cancerous growth). PDT is also unique for its ability to minimize pores and reduce oil glands, effectively treating acne vulgaris, acne rosacea and improve scarring from past acne.

It is also effective in promoting skin rejuvenation; healing sun damaged skin and acne treatment and is increasingly being used by skin cancer doctors and cosmetic physicians.

What does photodynamic therapy do?

A light sensitive chemical is applied to the skin followed by the use of a particular wavelength of light which is aimed at the target area. The light causes certain changes within the skin which clears the site of the infection or cancerous growth.

What does photodynamic therapy do?

This procedure takes a few hours to complete. Your skin is checked and any scabs or crusts removed.A light-sensitive cream (known as a photosensitizer) is applied to the target area of skin. This is covered with a dressing and left for up to 3 hours which gives it time to be absorbed by the skin. The dressing is then removed and the cream wiped off. The target area of skin is cleaned.

A bright red light is shone onto the target area of skin for 15 to 45 minutes. The treated area is then covered with a dressing which is left in place for 2 days.

After a couple of days you can remove this dressing. Wash the treated area as normal but dry it gently, e.g. pat it dry. A scab will have formed over the treated skin so take care not to dislodge this as this will prevent healing. Do not pick or scratch this either.

Wear a sun cream with a high sun protection factor (SPF) when outside to prevent sunburn. Avoid swimming until otherwise directed.

Who is not suitable for photodynamic therapy?

This treatment is not recommended for pregnant women or anyone suffering from porphyria (a disorder where the skin is extremely sensitive to sunlight).

What skin lesions are suitable for PDT?

Your dermatologist will advise if your skin lesion is suitable for PDT and what alternative treatments are available. In general, this treatment is possible for superficial and nodular subtypes of BCC, squamous cell carcinoma in situ (Bowen’s disease) and solar or actinic keratoses.

How long will a PDT procedure take?

The actual exposure to the light or laser will generally only take up to a few minutes, but the incubation time with the photosensitising chemical may take an hour or more.

Is PDT painful?

This varies from patient to patient and the location of lesions to be treated. If pain is experienced, it can have a stinging or burning quality. Discomfort can be minimized by taking painkillers such as paracetamol two hours before illumination. If required, the light exposure can be paused (with no adverse effect on the final outcome), so that additional pain relief such as a local anaesthetic can be given.
