Study Arms:
- Arm 1 - ALA (Type: EXPERIMENTAL): Patients receive topical ALA topical (aminolevulinic acid) 2 hours before PDT.
- Arm 2 (Type: EXPERIMENTAL): Patients receive topical ALA topical (aminolevulinic acid) 4 hours before PDT
- Arm 3 (Type: EXPERIMENTAL): Patients receive topical ALA (aminolevulinic acid) 24 hours before PDT. Each anatomic area is divided into subunits (e.g., right and left arm, right and left side of the face). The subunits are randomized to receive 1 or 2 pulses of the laser treatment
- Arm 4 (Type: EXPERIMENTAL): Vbeam laser pulse (photodynamic therapy) is applied to the subunit
- Arm 5 (Type: EXPERIMENTAL): Vbeam laser pulses (photodynamic therapy) are applied to the subunit. Patients may receive up to 3 treatments (including pretreatment, ALA, and PDT) at least 1 month apart

Based on this trial design, predict the completion outcome and termination type (if applicable).
