Brief summary
This is an investigator-blinded, prospective study of 20 subjects aged 13 through 18 with mild to moderate acne. Study subjects will be randomized to an internet survey group, in which an email link for a survey ascertaining the status of the subject's acne is sent weekly, or to a control group. All study subjects will use benzoyl peroxide 5% gel, and adherence and clinical improvement will be monitored over 12 weeks. The investigators hypothesis is that subjects in the internet survey group will have improved adherence to the study medication and clinical outcomes, because the weekly survey will remind subjects to use their medication.
Interventions
A weekly email link will be generated to an internet survey which questions subjects about their acne severity, compliance with the study medication, and attitudes toward acne and the study medication.
Topical benzoyl peroxide 5% gel, to be used once daily to the face.

Eligibility
Inclusion criteria
* male or female 13 to 18 years of age with a diagnosis of mild to moderate acne vulgaris by a dermatologist. * written consent of participation must be given by parent or guardian and child.
Exclusion criteria
* Age less than 13 or greater than 18 years of age. * Known allergy or sensitivity to topical benzoyl peroxide gel in the subject. * Inability to complete all study-related visits. * Introduction of any other prescription medication, topical or systemic, for acne vulgaris while participating in the study. * Subjects may not use topical retinoids or other benzoyl peroxide products, including Proactiv® or topical prescription medications while enrolled in the study. * Women that are actively trying to become pregnant or wish to become pregnant during the time frame the study is to take place will be excluded. * Subjects will be carefully selected for this study and only those deemed appropriate for treatment with benzoyl peroxide will be placed on this medication.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The Measured Adherence by the MEMS Cap in Relation to the Patient Reported Adherence Via the Internet Survey. | 12 weeks | Adherence will be objectively measured with the Medication Event Monitoring System (MEMS) cap and the percentage of prescribed doses taken will be reported. Study subjects' self-reported adherence (in the intervention group, via the weekly internet survey) will be compared to objectively measured adherence via MEMS caps. Adherence was monitored objectively with electronic monitors that recorded the date and time when the medication containers were opened (medication event monitoring system caps). Adherence was rated as a percentage of days the medication container was opened; adherence could be greater than 100% if the container was opened more than once per day. |

| The Change (Dynamic Assessment) From Baseline to End of Treatment in Lesion Counts. | Baseline to 12 weeks | Both inflammatory (papules, pustules and nodules) and non-inflammatory (open and closed comedones) acne lesions will be counted by a study investigator. Percentage change from baseline to the final study visit will be calculated. |

Outcome results
The Measured Adherence by the MEMS Cap in Relation to the Patient Reported Adherence Via the Internet Survey.
Adherence will be objectively measured with the Medication Event Monitoring System (MEMS) cap and the percentage of prescribed doses taken will be reported. Study subjects' self-reported adherence (in the intervention group, via the weekly internet survey) will be compared to objectively measured adherence via MEMS caps. Adherence was monitored objectively with electronic monitors that recorded the date and time when the medication containers were opened (medication event monitoring system caps). Adherence was rated as a percentage of days the medication container was opened; adherence could be greater than 100% if the container was opened more than once per day.

The Change (Dynamic Assessment) From Baseline to End of Treatment in Lesion Counts.
Both inflammatory (papules, pustules and nodules) and non-inflammatory (open and closed comedones) acne lesions will be counted by a study investigator. Percentage change from baseline to the final study visit will be calculated.
