Photodynamic therapy, also known as PDT, is a light-based treatment where a solution called Levulan is applied in the office to the face for 1-2 hours, making it more sensitive to light. The solution is then “activated” with blue light, red light, or Intense Pulsed Light. PDT can be used to address persistent acne, recurrent acne, back acne or acne in patients who do not or cannot take oral medications such as Accutane. This process attacks the oil glands and can dramatically reduce inflamed acne bumps, improve pore clogging, reduce pore size, and decrease overall oiliness of the skin. Blue or Pulsed Light PDT can improve acne, while PDT with red light can potentially inactivate the oil glands to produce long-term remission of acne.
Another common application of this technology is in the treatment of sun damaged skin and pre-cancerous non-healing scaly spots called actinic keratosis. Sun avoidance is a must for 48 hours immediately following PDT treatment. A course of treatment is usually consists of 4 sessions spaced about 4 weeks apart.
