What It Treats
PDT can treat the following skin conditions:
- Abnormal cells that cause actinic keratosis (pre-cancerous skin cells)
- Rosacea or redness
- Enlarged pores
Treatment and Recovery
For the treatment, a topical photosensitizing drug is applied to the skin and left to incubate for a period of up to several days (depending on the patient’s needs). Once incubated, a special wavelength light source is used to activate the drug, causing a sensation of tingling, warmth, heat, or burning in the affected area. Afterward, the area is washed and the patient returns home. Patients usually return to work within one to two days, and any side effects are usually mild and resolve on their own within a few weeks. Up to five treatment sessions spaced two to five weeks apart may be recommended for treatment, and maintenance treatments can be continued afterward.
