PhotoDynamic Therapy

PhotoDynamic Therapy

PhotoDynamic Therapy (PDT) is a non-surgical treatment that is used to improve the appearance of mild to moderate sun damage and for certain pre-cancerous lesions on all areas of the body.

How does the treatment work?

A naturally occurring substance called ALA is applied to the affected area. When applied to the skin, the ALA is absorbed into the abnormal or damaged skin cells. The length of incubation time will vary, depending on the area being treated e.g. arms & legs may require overnight incubation. Once the ALA has been absorbed after the appropriate incubation period, an LED light source is focused on the treated area for a period of time. When exposed to the light, the abnormal skin cells containing the ALA are selectively destroyed to ultimately reveal fresh and healthy skin cells, less sun damage and improved skin texture. PDT is highly effective in bringing to life aged skin, providing significant cosmetic benefits for sun damaged and aged skin, rosacea, acne, large pores and skin discolouration due to sun damage.

There is some discomfort associated with the treatment, and patients can expect to experience some redness, swelling and crusting post treatment. The extent of the downtime required post treatment varies, depending on the amount of damage being treated. Prior to treatment, a consultation with one of our Skin Therapists is required, as well as a skin check with a doctor.


PDT benefits include:

  • Minimal side effects & downtime
  • Rapid healing
  • Excellent cosmetic results
  • No systemic reaction
  • The treatment is able to be customised to your individual requirements
  • Can be repeated if necessary
  • Does not prevent patients from undergoing any other cosmetic, medical or surgical procedures in the future
