Photodynamic therapy, also known as PDT, is a treatment that has been primarily used in cancer patients. However, more recent developments of this procedure have made it available for patients that consider facial rejuvenation or would like to get rid of acne.
Candidacy for Photodynamic Therapy
When used for facial rejuvenation or acne, the ideal candidate for PDT should be in good health and have lighter skin. In patients with darker skin tones, the treatment may cause discoloration, which may be temporary or permanent. Patients that have a suntan are also not suitable for this type of treatment. A patient should avoid natural or artificial tanning for at least two months prior to a PDT treatment.
If the patient is sensitive to light or takes drugs that make her sensitive to light, the treatment should be performed with caution. Patients that have diabetes, an autoimmune condition such as lupus erythematosus or develop cold sores frequently should also consult a doctor prior to opting for photodynamic therapy. Antiviral tablets will be prescribed to prevent an outbreak of herpes in patients that carry the virus. Patients that have various allergies to drugs should be tested prior to applying the treatment.
