Photodynamic Therapy (PDT)
Is used for the management of sunspots or early skin cancers. Other uses described for PDT include reduction in acne and rosacea.
A special cream is applied to the skin for one hour prior to laser treatment. This medicated cream specifically is taken up into sun damaged cells and sebaceous glands of the skin. Once taken up by the cells, the laser then targets these cells more specifically.
What is the cream?
The cream contains a special agent called 5-amino levulinic acid (ALA). When absorbed into the skin it is metabolised best by sunspots, oil glands and acne spots. The laser beam then targets the ALA in the cell specifically which then destroys it.
What can I expect from treatment?
On the day of treatment the cream is applied to your skin and left to absorb for one to three hours. A mild burning like sensation may be experienced after treatment. Sun avoidance and sun protection with a broad brimmed hat and sunscreen is required for 2 days after treatment. The skin may be red and swollen for around 3-4 days and may feel dry for up to 7 days after treatment.
