Restore skin health with photodynamic therapy (PDT) at Paradise Dermatology. This innovative treatment targets precancerous cells, acne, sun-damaged skin, and rosacea by combining light-sensitive medication with precise light exposure. PDT is a non-invasive, effective way to address various skin conditions and support a healthier, clearer complexion.

Destroy Unwanted Growths
Without Surgery

Photodynamic therapy (PDT) is a minimally invasive skin treatment that targets specific skin conditions by using a light-sensitive medication activated by a special light source. This process selectively destroys abnormal or damaged cells while preserving healthy tissue, making it ideal for treating conditions like precancerous lesions (actinic keratosis), acne, rosacea, and sun damage. PDT is especially beneficial for patients seeking an alternative to surgical procedures, offering effective results with minimal downtime. At Paradise Dermatology, we provide PDT to help patients achieve healthier, rejuvenated skin safely.

Photodynamic Therapy (PDT) Treats:

  • Precancerous lesions, like actinic keratosis
  • Persistent or severe acne
  • Sun-damaged skin with visible discoloration
  • Rosacea with redness and inflammation
  • Certain superficial skin cancers
  • Enlarged oil glands (sebaceous hyperplasia)

How Does Photodynamic Therapy (PDT) Work?

Photodynamic therapy (PDT) combines a photosensitizing agent, often applied as a topical solution, with a light source to target damaged or abnormal cells. Once applied to the skin, the photosensitizing agent accumulates in these abnormal cells. When exposed to a specific wavelength of light, the photosensitizer activates, producing a reactive oxygen species that destroys the affected cells without harming surrounding tissue. This makes PDT highly effective in treating conditions like precancerous lesions, acne, and sun-damaged skin.

What Happens During Photodynamic Therapy (PDT)?

During photodynamic therapy (PDT), a light-sensitive medication is first applied to the treatment area, often as a topical solution. This medication is then absorbed by targeted cells over a short incubation period. The length of this period can vary but generally lasts from 15 minutes to an hour, depending on the treatment plan and the condition being addressed. Once the medication has been absorbed, you will sit under a light source calibrated to activate the photosensitizer. This light exposure usually lasts 5 to 10 minutes. During this stage, the photosensitizer reacts with light, releasing oxygen molecules that destroy the targeted cells. Afterward, aftercare instructions are provided to protect the treated area as it heals.

Benefits of Photodynamic Therapy (PDT):

  • Targets abnormal cells with minimal impact on surrounding healthy tissue
  • Non-invasive alternative to surgical treatments
  • Effective for multiple skin conditions, including precancerous lesions and acne
  • Minimal downtime and quick recovery for most patients
  • Can improve overall skin tone and texture
  • Low risk of scarring compared to traditional procedures
  • Reduces the need for systemic medications, like oral antibiotics

When Will I Start to See Results?

Results vary depending on the condition treated, but many patients see an improvement in their skin within a week. Full results typically appear within several weeks as the treated cells are gradually cleared away and replaced with healthier ones. Conditions like acne and sun damage may require multiple sessions for optimal results.

Photodynamic Therapy (PDT) FAQs

What Are the Side Effects of Photodynamic Therapy?

PDT is generally well-tolerated, but you may experience mild redness, swelling, or peeling in the treated area. These side effects are typically temporary and resolve within a few days. Some patients report a tingling or stinging sensation during light exposure, but this usually subsides once the treatment is complete.

How Much Downtime Should I Expect After Photodynamic Therapy?

There is minimal downtime with PDT, though some redness and sensitivity may last a few days. You must avoid direct sunlight for at least 48 hours, as your skin will be more sensitive. Staying indoors, wearing sunscreen, and using gentle skincare products can support a faster recovery.

How Many Sessions of Photodynamic Therapy Will I Need?

The number of PDT sessions depends on your skin condition and treatment goals. While some patients achieve desired results with a single session, others, particularly those treating acne or sun damage, may benefit from a series of treatments spaced several weeks apart. Your dermatologist will customize a treatment plan based on your needs.

What Aftercare is Necessary Following Photodynamic Therapy?

After PDT, it’s essential to protect your skin by avoiding sun exposure and wearing a broad-spectrum sunscreen daily. Your skin may feel sensitive, so use gentle skincare products and avoid exfoliants or harsh ingredients for at least a week. Moisturizing frequently can help soothe any temporary dryness or peeling.
