How Does Photodynamic Therapy Work?
Photodynamic Therapy (PDT) requires three components: a photosensitizing medication, a light source, and oxygen. Levulan is the medication used to create porphyrins, light-absorbing molecules, in damaged or abnormal cells. Then, a medical-grade light source (blue, red, or intense pulsed light) focuses on the skin and activates the medication. Combined with oxygen, acne cells and acne-causing bacteria are destroyed, oil-producing sebaceous glands are reduced in size and activity, and acne scars are diminished.
PDT can also improve sun damage, rosacea, hidden lesions, and other conditions occurring simultaneously with the acne. PDT is proven effective against even resistant acne and severe cases of acne and extensive acne scarring. PDT offers benefits over other therapies, including:
- Targeting only damaged cells to maintain skin integrity
- Reducing the size and activity of sebaceous glands
- Killing acne-causing bacteria
- Fading existing acne scars and not contributing to new scars
- Effective for other skin conditions, such as age spots, sun damage, and rosacea
Am I a Good Candidate?
Patients diagnosed with actinic keratoses, moderate to severe sun damage or rosacea, cystic acne, sebaceous hyperplasia, or other resistant acne are good candidates. Those prescribed Accutane must stop taking it before PDT treatment. Schedule a consultation at Colorado Skin & Vein to get started.
