Photodynamic therapy (PDT) is a medically used treatment that combines a light-sensitive medication with a specific light source to target abnormal or damaged skin cells.
It is commonly used in clinical settings for the management of conditions such as actinic keratoses (sun-damaged skin lesions) and may be used in selected cases of superficial non-melanoma skin cancers, including basal cell carcinoma and squamous cell carcinoma, following medical assessment.
PDT may also be used for certain cases of acne that have not responded to conventional treatments.
Treatment suitability is determined following a thorough clinical evaluation.
 How does PDT work?
PDT involves the application of a photosensitising agent to the affected area, which is then activated using a specific wavelength of light.
This reaction produces oxygen molecules that selectively target abnormal or damaged cells while minimising impact on surrounding healthy tissue.
Over time, treated cells break down and are naturally removed by the body.
