Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | 10-minute Incubation With Microneedle Roller & Sham | 10-minute topical aminolevulinic acid incubation group. Subjects randomized by binary randomization into each treatment group and undergo secondary binary randomization for microneedle roller treatment (vs. sham microneedle) to the right or left side of the face. Blue light therapy follows.~Microneedle Roller: The study device (MR200, Clinical Resolutions Laboratory, Inc.) is a disposable roller equipped with stainless steel needles that are 200 micrometers in length.~Aminolevulinic Acid: Levulan® Kerastick® DUSA Pharmaceuticals, Inc., Wilmington, MA~Blue Light: Blu-U unit (DUSA Pharmaceuticals, Inc., Wilmington, MA | 0 | 16 | EG000 |
| Group 2 | 20-minute Incubation With Microneedle Roller & Sham | 20-minute topical aminolevulinic acid incubation group. Subjects randomized by binary randomization into each treatment group and undergo secondary binary randomization for microneedle roller treatment (vs. sham microneedle) to the right or left side of the face.
