Photodynamic Therapy for Actinic Keratosis and Sun Damage in Atlanta, GA

Schedule An Appointment

Has your skin experienced damage from excessive sun exposure? If so, you may be suffering from photodamage—a type of skin damage characterized by changes in pigmentation, fine lines and wrinkles, as well as a rougher skin texture. Photodamage can also lead to the appearance of precancerous lesions known as actinic keratoses. These lesions, if not properly treated, can develop into squamous cell skin cancers. Our board-certified dermatologist Dr. Elise Barnett can correct mild to moderate levels of photodamage and eliminate these precancerous growths through the use of photodynamic therapy (PDT).

What is Photodynamic Therapy (PDT)?

Photodynamic Therapy is a non-invasive treatment that uses a combination of a photosensitizing agent and a specific wavelength of light to target and destroy abnormal skin cells. This treatment is highly effective in addressing a variety of skin concerns, including:

  • Acne: Photodynamic Therapy reduces severe acne by targeting the oil glands and bacteria responsible for breakouts.
  • Actinic Keratosis: This pre-cancerous condition is treated effectively with Photodynamic Therapy, reducing the risk of progression to skin cancer.
  • Sun Damage: Photodynamic Therapy helps to reverse sun damage, including sunspots and fine lines, restoring your skin’s natural glow.
  • Rosacea: By reducing inflammation and targeting the blood vessels, Photodynamic Therapy helps manage the symptoms of rosacea.

How Photodynamic Therapy (PDT) Works and Its Benefits:

  • Application of the Photosensitizing Agent: The treatment begins with the application of a photosensitizing agent to the targeted area of your skin. This agent is absorbed by abnormal cells, making them more sensitive to light.
  • Activation with Light: After allowing the photosensitizing agent to absorb into the skin, a specific wavelength of light is used to activate the agent. This light targets and destroys the abnormal cells while leaving healthy cells unharmed.
  • Post-Treatment Care: Following the procedure, your skin will be sensitive to light, and it's essential to avoid direct sunlight for a few days. Our team will provide you with detailed post-treatment care instructions to ensure optimal results.
  • Non-Invasive: PDT is a non-invasive treatment that does not require surgery, making it a safer option for many patients.
  • Minimal Downtime: Most patients experience minimal downtime, allowing you to return to your daily activities quickly.
  • Effective Results: PDT offers significant improvements in skin texture, tone, and overall appearance.
  • Versatile Treatment: Suitable for a wide range of skin types and conditions.
