PHOTODYNAMIC THERAPY (PDT) FOR ACNE

A Medical Alternative to Systemic Acne Medications

Physician-guided treatment — performed by Dr. Jozef Tryzno

Photodynamic therapy (PDT) is a medically supervised treatment option for selected patients with moderate to severe inflammatory acne. PDT may be considered when acne has not responded adequately to topical therapy or when long-term systemic treatments are not appropriate, not tolerated, or not desired.

At International Vein & Skin Institute (IVSI), PDT is used as part of a comprehensive acne management strategy, guided by medical evaluation and individualized treatment planning.

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 at multiple biological levels.

PDT is designed to:

Reduce sebaceous gland activity
Decrease acne-causing bacteria
Suppress inflammatory pathways involved in acne formation

Unlike cosmetic light treatments, PDT is intended to address the underlying drivers of inflammatory acne, not just surface appearance.

HOW PDT IS PERFORMED

PDT typically involves three steps:

Application of a photosensitizing agent
A topical medication (such as aminolevulinic acid, ALA) is applied to the affected skin.
Controlled incubation period
The medication is allowed to penetrate and selectively accumulate in acne-prone structures.
Light activation
The treated skin is exposed to a specific light source (such as blue light or pulsed dye laser), activating the medication and initiating a therapeutic response.

Treatment parameters are adjusted based on acne severity, skin type, and treatment goals.

WHEN PDT MAY BE CONSIDERED

For selected patients, PDT may serve as an alternative or adjunct to systemic acne medications, including isotretinoin.

PDT may be appropriate for patients who:

Have moderate to severe inflammatory acne
Have not responded adequately to topical therapies
Prefer to avoid or cannot tolerate long-term systemic treatments
Have experienced side effects or limitations with oral acne medications
Are seeking a medically guided, non-systemic treatment option

While isotretinoin remains an important and effective treatment for many patients, PDT offers a non-systemic option that may help control acne without long-term oral medication exposure.

EXPECTED BENEFITS AND LIMITATIONS

Potential benefits of PDT may include:

Reduction in inflammatory acne lesions
Decreased oil production
Improvement in overall skin inflammation
Reduced reliance on long-term oral medications in selected cases

Important limitations:

PDT does not permanently prevent new acne from forming
Multiple treatment sessions may be required
Results vary based on acne severity, skin type, and individual response
Ongoing medical acne management may still be necessary

PDT is not a cure for acne and does not replace medical evaluation or ongoing management when needed. Treatment response varies, and additional medical or procedural therapies may still be required as part of a comprehensive acne management plan.

RECOVERY AND TEMPORARY EFFECTS

Common temporary effects following PDT may include:

Redness
Peeling or flaking
Skin sensitivity
Temporary photosensitivity

Recovery time varies depending on treatment intensity and individual skin response. Post-treatment care instructions are provided to support healing and minimize irritation.

PDT AND ACNE SCARRING

PDT is used to treat active inflammatory acne, not established acne scars. However, by helping control inflammation, PDT may reduce the risk of future scarring.

Once acne is controlled and skin inflammation is stabilized, scar-directed treatments—such as vascular lasers or texture-focused resurfacing—may be considered separately, when appropriate.

INDIVIDUALIZED TREATMENT PLANNING

Acne is not a single condition, and no single treatment is appropriate for every patient.

During your visit, Dr. Tryzno will:

Review your acne history and prior treatments
Perform a detailed skin examination
Determine whether PDT is appropriate for your acne pattern
Discuss alternative and adjunctive treatment options
Review expected outcomes and recovery

Treatment decisions are based on medical findings, patient preferences, and long-term skin health.

WHEN TO CONSIDER PDT EVALUATION

A consultation may be appropriate if:

Acne remains active despite topical treatment
Systemic medications are not desired or not tolerated
Acne is inflammatory rather than primarily comedonal
You are seeking a medically guided, non-systemic option

Determine Whether PDT Is Appropriate

Photodynamic therapy might be considered after medical evaluation and review of prior treatments.
