Restore your skin’s health with photodynamic therapy (PDT) at Abrams Dermatology. This non-invasive treatment effectively targets and treats actinic keratosis, acne, hidradenitis suppurativa, and other inflammatory skin conditions. PDT uses a photosensitizing agent activated by light to eliminate precancerous lesions and acne-causing bacteria, promoting clear, healthy skin.
Treat Inflammatory Conditions and Restore Healthy Skin
Photodynamic therapy (PDT) is a non-invasive treatment that combines a photosensitizing agent, aminolevulinic acid (ALA or Levulan), with a specific light source to target and destroy abnormal skin cells. PDT is a two-step process commonly used to treat conditions such as actinic keratosis, acne, and hidradenitis suppurativa. First, the ALA is applied to the skin and absorbed by targeted cells. Then, the treated area is exposed to light, activating the agent to eliminate precancerous lesions and acne-causing bacteria, leading to clearer, healthier skin.
Photodynamic Therapy (PDT) Is the Ideal Treatment For:
- Actinic keratosis (precancerous skin lesions)
- Mild to resistant acne (acne that doesn’t respond to traditional treatments)
- Hidradenitis suppurativa (painful lumps in areas like the armpits and groin)
- Sun-damaged skin (discoloration, roughness, or other damage from UV exposure)
- Other inflammatory skin conditions characterized by redness, swelling, and irritation
How Does Photodynamic Therapy (PDT) Work?
Photodynamic therapy (PDT) begins with applying a photosensitizing agent, aminolevulinic acid (ALA or Levulan), to the affected skin. ALA is absorbed by abnormal or damaged cells, including precancerous cells and acne-causing bacteria. After a short period, the treated area is exposed to a specific light source, such as the Blue-U light. This light activates the ALA, targeting and destroying the unwanted cells. The activated ALA produces a reaction that eliminates abnormal cells while sparing healthy tissue, leading to clearer, healthier skin.
The Unique Benefits of Photodynamic Therapy (PDT):
- Non-invasive and minimal discomfort during treatment
- Targets specific areas without affecting surrounding healthy tissue
- Can be repeated multiple times at the same site if needed
- Short treatment duration, usually done as an outpatient procedure
- Minimal scarring and faster recovery compared to surgical treatments
- Effective for various skin conditions, including acne and precancerous lesions
Photodynamic Therapy (PDT) FAQs
What Happens During Photodynamic Therapy (PDT)?
During your PDT session, a photosensitizing agent called aminolevulinic acid (ALA or Levulan) is applied to the affected skin and allowed to absorb for about 15 minutes to 1 hour, depending on the treatment plan. Afterward, the treated area is exposed to a specific light source, such as the Blue-U light, for approximately 6-10 minutes. This light activates the ALA, targeting and destroying abnormal skin cells, bacteria, or other problem areas.
What Are the Side Effects of Photodynamic Therapy (PDT)?
PDT is generally well-tolerated, but you may experience mild side effects, such as redness, swelling, itching, or a burning sensation on the treated skin. These effects usually subside within a few hours to a few days.
Is There Any Downtime After Photodynamic Therapy (PDT)?
There is minimal downtime with PDT, but you must avoid direct sunlight and bright indoor light for at least 48 hours after treatment. The treated skin will be more sensitive during this period, so it’s recommended to wear sunscreen and protective clothing, such as hats or scarves. You may also experience mild redness, similar to a sunburn, which can last a few days.
How Long Does It Take to See the Results From Photodynamic Therapy (PDT)?
The results from PDT can vary depending on the condition being treated. For conditions like acne, you may see improvements within a few days to weeks after the first session. When treating actinic keratosis or other precancerous lesions, noticeable results can take several weeks as the skin renews. Multiple sessions may be necessary for optimal results.
How Many Sessions of Photodynamic Therapy (PDT) Will I Need?
The number of PDT sessions needed depends on the condition being treated and its severity. Generally, patients require at least 3 sessions spaced 2-4 weeks apart. Additional treatments may be recommended for more resistant conditions or severe acne. Maintenance treatments may also be scheduled as needed to sustain the results over time.
