Acne Vulgaris
Conditions
Brief summary
The aim of our study is to determine the time to resolution of individual acne lesions using a popular handheld heat based device in comparison to no treatment and to standard topical therapy with benzoyl peroxide in order to determine its effectiveness in the spot treatment of acne vulgaris. Patient satisfaction and potential side effects will be examined as well.
Interventions
DEVICESplit face: handheld acne heat based device (Zeno Hot Spot) and no treatment
Subjects will apply the actual device to every inflammatory acne facial lesion on one half of the face and no treatment to every inflammatory acne lesion on the other half of the face at 6 hour intervals for a total of 3 treatments. Follow up will occur daily over a 5 day period.
DEVICESplit face: handheld acne heat based device, Zeno Hot Spot, and topical benzoyl peroxide 4%
Subjects will apply the actual device to every inflammatory acne facial lesion on one half of the face at 6 hour intervals for a total of 3 treatments. Subjects will apply benzoyl peroxide to the other half of the face daily for 5 days.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Time to resolution of individual acne lesions | 5 days | Subjects will be photographed daily and the progression of individual acne lesions will be followed. Time to resolution of each lesion will be determined for the various treatment groups. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Device tolerability | 5 days | Device tolerability will be assessed daily by asking the subject about adverse effects experienced from the treatments. At the end of 5 days, subjects will be asked to rate the various treatments based on ease of use and how much the side effects bothered him or her. |
| Split-face investigator's static global assessment | 5 days | Split-face investigator's static global assessments will be conduced daily on subjects for 5 days. |
| Acne lesion counts | 5 days | Lesion counts will be performed daily for 5 days. |
