Photodynamic therapy in dermatology: established and new indications

Area of Science:

• Dermatology
• Photomedicine
• Oncology

Background:

• Photodynamic therapy (PDT) is an established treatment for keratinocytic skin cancers.
• Standardized protocols exist for approved indications using specific light sources.
• Daylight PDT demonstrates advantages in patient comfort and acceptance.

Purpose of the Study:

• To review the established and emerging applications of photodynamic therapy in dermatology.
• To highlight the efficacy and patient benefits of daylight- versus conventional PDT.
• To explore the potential of PDT for inflammatory, infectious, and aesthetic dermatological conditions.

Main Methods:

• Review of existing literature and clinical studies on photodynamic therapy.
• Comparison of treatment outcomes, including healing rates, recurrence, cosmetic results, and patient-reported pain.
• Analysis of evidence for newer, non-approved indications of PDT.

Main Results:

• PDT shows high efficacy in treating in situ skin cancers with good cosmetic outcomes and low recurrence.
• Daylight PDT is associated with significantly less pain and higher patient acceptance than conventional PDT.
• Emerging evidence supports PDT for inflammatory dermatoses, infectious diseases, and skin rejuvenation.

Conclusions:

• Photodynamic therapy is a versatile and effective treatment for various dermatological conditions.
• Daylight PDT offers a more comfortable and patient-friendly alternative for approved indications.
• Further research and potential approval for new indications will expand PDT's role in dermatology.
