Brief summary: The purpose of this study is to determine whether an automated electronic reminder system using text messages sent to patient's cell phones will help patients with acne be more compliant with their topical medications and lead to an improvement of their acne.

Hypothesis: Automatically delivered electronic reminders in the form of text messages will increase acne patient adherence to topical medications and consequently result in better treatment outcome and higher patient satisfaction

Detailed description: Patient non-compliance with topical medication use is a significant determinant of treatment failure resulting in both patient and physician frustration with outcome and leading to suboptimal medical care. It is important to address ways to improve patient compliance both from a medical and economic standpoint, as adequate use of medications could lead to a reduction of unnecessary office visits and a more cost-effective use of prescribed medications.

Patients with mild to moderate acne will be prescribed a standard treatment regimen with clindamycin/benzoyl peroxide gel in the mornings and adapalene gel in the evenings. Half of the subjects will then be randomly assigned to receive customized text messages instructing them twice a day to apply their morning and evening cream as prescribed, with the remainder of subjects serving as controls. Each medication tube supplied to every subject will be fitted with an electronic Medication Event Monitoring System cap (MEMS cap) which has the ability to record the date and time of every opening/closing of the tube. This data will serve as an objective measure of medication use and will be used to determine whether the reminder messages resulted in a higher and more consistent use of the prescribed medications.

Specific Aims:

The primary aim of the study is to determine whether automated text messages produce increased adherence with medication use in the Reminder group compared to the Control group over the 12 week study duration.

Improvement in acne will be measured using full face lesion counts, Investigator Global Assessment Score (IGA) and subject Global Assessment Score (SGA). Quality of life and satisfaction will be measured using the Dermatology Life Quality Index (DLQI), and patient satisfaction surveys.

Eligibility criteria: Inclusion Criteria:

* Must be able to adhere to study visit schedule and other protocol requirements.
* Must avoid prolonged sun exposure and avoid use of tanning booths or other ultraviolet light sources during the study.
* Must agree not to use any other prescription or over the counter medications other than the ones prescribed by the study protocol.

* Have used any investigational drug within the previous 4 weeks or 5 times the half life of the investigational drug, whichever longer.
* Have received phototherapy or use a tanning booth within 4 weeks prior to enrollment
* Currently taking any systemic medications that could affect evaluation of acne (including, but not limited to antibiotics, retinoids, biologic disease modifying agents, chemotherapeutic agents, anti-epileptic agents or EGFR-receptor antagonists)
* History of chronic or recurrent infectious disease, including, but not limited to folliculitis, infected skin wounds or ulcers and recurrent herpes simplex infections.
* Known hypersensitivity response, including anaphylaxis, to any of the compounds used for treatment (e.g: clindamycin, retinoids).
* Known substance abuse (drug or alcohol) problem within the previous 12 months.
* Presence of beard or facial hair which might interfere with study assessments
* Participating in another clinical trial using an investigational agent or procedure during participation in the study.
* Are pregnant or planning pregnancy or a surgery during the participation in the study
