What is PhotoDynamic Therapy (PDT)?

PDT uses both chemistry and light therapy to target precancerous lesions, called actinic keratosis, as well as stubborn acne scars and sun-damage. It can also reduce the visual signs of aging in general. The FDA approves PDT for treating actinic keratosis, which are precancerous lesions that are best removed upon discovery. Actinic Keratosis are rough, dry, scaly patches caused by sun exposure. Before any kind of treatment is administered, however, Actinic Keratosis should be properly diagnosed by a Licensed physician.

Photo Dynamic TherapyPDT is a two-step procedure. First, a photosensitizing agent is topically applied to the skin and taken up by the targeted skin area. The second step involves the application of light on the area of skin being treated. PDT is a very precise treatment and only damages the targeted skin without causing harm to the surrounding healthy skin.

Rejuve Clinic uses Levulan, 5-Aminolevulinic acid, as the photosensitizing agent. Levulan is applied to the skin condition, and the targeted skin cells absorb it and convert it into chemical molecules called porphyrins. Precancerous and cancerous cells tend to accumulate more porphyrins than normal cells, which is why PDT is a standard treatment for actinic keratosis and another kind of skin cancer called basal cell carcinoma. Porphyrins increase the targeted cell’s ability to absorb certain wavelengths of light.

During the next step of PDT, a blue light will be applied to the targeted skin area. A blue light is used, because it activates porphyrins to generate free radicals inside the targeted cells. These free radicals will ultimately cause the destruction of the cells via necrosis (cell death) or apoptosis ( programming the cell to die spontaneously). The end result is the removal of precancerous skin lesions and clearer, healthier-looking skin.

PDT is also an effective treatment against acne. Bacteria called Propionibacterium acnes, overproduce during an active acne flare-up. These bacteria are excellent accumulators of porphyrins (similar to precancerous cells), which is why PDT is effective.

It has also been observed that PDT boosts the production of collagen, a key structural protein in the skin. Increased collagen translates into a tighter, younger-looking and more vibrant complexion.

The Conditions PDT Treats:

PDT is effective for Actinic Keratosis, Sun-damaged skin, the generalized visible signs of aging, acne and acne scars. This treatment is not recommended for individuals with a known sensitivity to light or a known allergy to porphyrins. Call our clinic today to see if PDT is right for you.

What to Expect:

 Photo Dynamic Therapy NYC

Before the PDT procedure, your licensed skin care expert will have a discussion with you about your needs, desires, and expectations. We will also inquire about your medical history, medicines you may be taking as well as your daily lifestyle. During the consultation, we will also examine your skin condition to ensure a proper diagnosis is made. This is also the time for you to ask any questions you may have and share your concerns. Our main goal is to make sure you are an informed part of the treatment team and are totally comfortable with the procedure. The treatment will be explained thoroughly, so you know what to expect

At the start of the procedure, Levulan, a photosensitizing agent, will be applied to the area of skin being treated. Once it is absorbed, a blue light (BLU-U® light) will be applied to the skin condition for twenty minutes or more. The duration of blue light exposure depends on the specific characteristics of the skin condition. Some patients feel a burning or tingling sensation during this time. After the treatment, you will be instructed to avoid sun exposure and wear a dermatologist-recommended sunscreen. It is very important to minimize your sun exposure as the sun can damage the treated area. As your skin heals over the following weeks, you may experience redness, swelling and a stinging sensation. Over time, your skin will flake, and fresh new skin will appear. You will see significant improvements after one PLT treatment, however, maintenance treatments are often required and should be scheduled by your licensed skincare specialist.

Negative side effects are rare, and include prolonged erythema, crusting, blistering, erosions, pigmentation and eye damage.


PDT is an excellent, noninvasive and effective treatment against specific skin conditions. It works great against precancerous lesions, called Actinic keratosis, and can also be an effective option for acne, acne scars and sun-damaged, aged skin. It is a fast treatment with little preparation time. PDT requires little downtime, although it is pertinent that sun exposure is minimized. The end result is a healthier glow and rejuvenated skin.
