Laser-Assisted Photodynamic Therapy: Two Novel Protocols for Enhanced Treatment Results.

<p>Photodynamic therapy (PDT) uses a topical photosensitizing agent which is activated by a light source to cause destruction of specific cells. Commonly used for the treatment of actinic keratoses and photodamage, PDT can also be used for other conditions including acne and sebaceous hyperplasia. Here we report our experience with two treatment protocols. The first protocol utilizes laser assisted delivery of topical 5-aminolevulinic acid for enhanced efficacy of blue light photodynamic therapy in the treatment of actinic keratoses and photodamage. The second protocol utilizes red light photodynamic therapy followed by pulsed dye laser to effectively target sebaceous glands in patients with extensive sebaceous hyperplasia.</p> <p><em>J Drugs Dermatol. 2017;16(4):329-331.</em></p>.
