PHOTODYNAMIC THERAPY (PDT) FOR ACNE

Physician-Performed Treatment for Inflammatory Acne

Photodynamic therapy (PDT) is a physician-performed treatment for selected patients with moderate to severe inflammatory acne. PDT combines a topical photosensitizing agent with controlled light activation to target sebaceous activity and inflammatory processes involved in acne.

At International Vein & Skin Institute, PDT is personally performed by Jozef Tryzno, MD, and incorporated into an individualized acne treatment based on the type and severity of active disease and previous treatment response.

WHAT IS PHOTODYNAMIC THERAPY (PDT)?

Photodynamic therapy is a multi-step medical treatment that combines a topical photosensitizing agent with controlled light activation to target acne through several biological mechanisms.

PDT is designed to:

Reduce sebaceous gland activity
Decrease acne-associated bacterial activity
Reduce inflammatory activity involved in acne

PDT is used to address active inflammatory acne, rather than established acne scarring or other residual skin changes.

HOW PDT IS PERFORMED

PDT typically involves three steps:

Application of a photosensitizing agent
A topical photosensitizing agent is applied to the treatment area.
Controlled incubation period
The photosensitizing agent is allowed to remain on the skin for a controlled period before light activation.
Light activation
The treated skin is exposed to a controlled light source. At IVSI, blue light and/or Pulsed Dye Laser (PDL) may be used for activation based on the treatment protocol.

Treatment parameters are selected according to acne severity, skin characteristics, and clinical response.

WHEN PDT MAY BE CONSIDERED

PDT may be considered as an adjunct or non-systemic treatment option for selected patients with inflammatory acne.

PDT may be appropriate for patients who:

Have moderate to severe inflammatory acne
Have not responded adequately to topical treatment
Prefer to avoid or cannot tolerate systemic treatment
Have experienced limitations with oral acne medications
Are seeking a non-systemic treatment option as part of medical acne management

PDT does not replace medical acne management. Treatment selection depends on the type and severity of acne, previous treatment response, and individual clinical findings.

EXPECTED BENEFITS AND LIMITATIONS

Potential benefits of PDT may include:

Reduction in inflammatory acne lesions
Decreased sebaceous activity and oil production
Reduction in overall skin inflammation
Reduced reliance on oral acne medications in selected patients

Important limitations include:

PDT does not permanently prevent new acne lesions from developing
Multiple treatment sessions may be required
Treatment response varies between patients
Ongoing medical acne management may still be necessary

PDT is not a cure for acne. Additional medical or procedural treatment may be incorporated into the overall acne management plan based on clinical response.

RECOVERY AND TEMPORARY EFFECTS

Temporary effects following PDT may include:

Redness
Peeling or flaking
Skin sensitivity
Temporary photosensitivity

The degree and duration of these effects vary with treatment intensity and individual skin response. Post-treatment instructions are provided to support appropriate healing and minimize unnecessary irritation.

PDT AND ACNE SCARRING

PDT is used to treat active inflammatory acne, not established acne scars. Controlling active inflammatory disease is an important part of limiting continued skin injury before scar-directed treatment is considered.

Once active acne is adequately controlled, established redness, pigmentation, and textural scarring can be evaluated separately for appropriate treatment.
