What to Expect from Photodynamic Therapy: Treatment, Recovery, and Results
If you’ve been diagnosed with sun damage or precancerous skin lesions, you may have heard about Photodynamic Therapy (PDT) as an effective treatment option. But what exactly does the process involve — and what should you expect before, during, and after treatment?
At Summit Dermatology in Medford, Oregon, we use Photodynamic Therapy to help patients throughout Southern Oregon treat damaged skin, improve skin health, and reduce the risk of future skin cancer — all with a targeted, dermatologist-guided approach.
What Is Photodynamic Therapy (PDT)?
Photodynamic Therapy is a specialized dermatology treatment that uses a light-sensitive solution combined with a controlled light source to target damaged or abnormal skin cells.
It’s most commonly used to treat:
Actinic keratoses (precancerous lesions)
Sun-damaged skin
Certain types of acne
Uneven skin texture and tone
This treatment works by selectively destroying damaged cells while leaving healthy tissue largely unaffected — making it both effective and precise.
What Happens During a PDT Treatment?
Photodynamic Therapy is typically performed in-office and involves a few key steps:
1. Skin Preparation
Your provider will cleanse the treatment area and may gently prep the skin to allow better absorption of the solution.
2. Application of the Light-Sensitizing Solution
A topical medication is applied to the skin and left to absorb for a specific period of time. This solution targets abnormal or damaged cells.
3. Light Activation
Once the solution has been absorbed, a specialized light is used to activate it. This step destroys targeted cells while stimulating skin renewal.
Total appointment time: Usually 1–2 hours depending on the treatment area.
What to Expect During Recovery
Recovery is one of the most important parts of PDT — and proper aftercare ensures the best results.
After treatment, you may experience:
Redness similar to a sunburn
Mild swelling or sensitivity
Peeling or flaking as damaged skin sheds
Most patients recover within several days to a week, depending on the intensity of treatment.
Important: Your skin will be highly sensitive to light immediately after treatment. Strict sun avoidance and protection are essential during the first 24–48 hours.
Your provider will give you detailed aftercare instructions and may recommend medical-grade skincare to support healing.
Results: What Improvements Can You Expect?
Photodynamic Therapy doesn’t just treat visible damage — it improves overall skin health.
Patients often notice:
Reduction in precancerous lesions
Smoother skin texture
More even tone
Healthier, clearer-looking skin
Results continue to improve as your skin heals and regenerates. Many patients benefit from a series of treatments for optimal outcomes.
