Acne vulgaris is a multifactorial, highly prevalent dermatologic condition that results in visible lesions that can be quite disfiguring. Consequently, individuals with acne often suffer from a wide range of psychological manifestations. Although there is consensus that combination therapy is most effective in treating acne, researchers are constantly striving to develop new treatment. Microcurrent therapy (MCT) is a non-invasive modality that has successfully been used to promote wound healing and has been routinely used in aesthetics. Use of MCT alone or in combination with current successful treatment such as blue light phototherapy (BLP), may hold promise for acne treatment. The investigators propose to conduct a small randomized control trial to determine the safety and preliminary efficacy of a novel combination therapy to treat acne vulgaris. The investigators will recruit up to 60 males and females and randomly assign them to one of 3 arms: 1) BLP; 2) MCT; and combination therapy (BLP and MCT). The investigators will assess physiological parameters (number of acne lesions, amount of sebum produced, degree of acne severity) and psychosocial factors (dermatologic quality of life, social anxiety, depressive symptomatology, self-esteem). Participants will complete a baseline assessment prior to initiating treatment and a follow-up assessment at 4 weeks post termination of treatment. The investigators will conduct intermediary assessments at weeks 3 and 5 and 1 week post termination of the treatment. The investigators will use measures of central tendency to describe the sample and repeated measures analysis of variance to compute the main and interaction effects.
Overview: The goal of this study is to conduct a small randomized control trial (RCT) to test the safety and preliminary efficacy of a novel combination therapy to treat acne vulgaris. The investigators will also explore the effects of the treatments on psychosocial factors (Dermatology Life Quality Index (DLQI), social anxiety, depressive symptomatology, and self-esteem). The RCT will have 3 arms: 1) FDA approved treatment: blue light phototherapy (BLP); 2) Microcurrent therapy (MCT); and 3) combination therapy (BLP + MCT). The main outcomes will be: 1) number of acne lesions; 2) amount of sebum produced, 3) degree of acne severity; and 4) improvement in dermatologic quality of life. The specific aims of the study are:
Aim 1: To explore the use of MCT to improve blood flow and lymphatic drainage and promote tissue repair in patients with acne vulgaris.
Aim 2: To examine the safety and preliminary efficacy of enhancing traditional blue light therapy treatment with microcurrent therapy (BLP + MCT) to promote faster healing in patients with acne vulgaris.
Aim 3: To determine if combination therapy is a more effective (fewer number of acne lesions, decreased amount of sebum produced, lesser degree of acne severity and greater improvement in dermatologic quality of life) for acne than either type of monotherapy.
Aim 4: To explore the effects of the three modalities on psychosocial factors (social anxiety, depressive symptomatology, and self-esteem).
The investigators will recruit up to 60 males and females and randomly assign them to one of 3 treatment arms (blue light phototherapy (BLP); microcurrent therapy (MCT); and combination therapy (BLP and MCT). All participants will complete a baseline assessment prior to initiating treatment one follow-up assessment at 4 weeks post termination of treatment. During the treatment phase, the investigators will conduct intermediary assessments to track the progression of the treatment over time at weeks 3 and 5 as well as 1 week post the termination of the treatment (week 6). The investigators will conduct both physiological and psychosocial assessments; the content of the intermediary assessment will be much less than the other 3 assessments to reduce participant data. The most comprehensive assessments will be conducted at baseline and one follow-up points and will consist of all of the physiological and psychosocial factors as well as demographic factors that will be collected exclusively at the baseline assessment. At the intermediary assessments, the investigators will collect the number of acne lesions, amount of sebum produced and dermatologic quality of life. Psychosocial data will be collected via computer-assisted self-interviews (CASI). Physiological data will be entered into the computer program by research staff.
Procedures for collecting psychosocial data: All assessments will be conducted using computer-assisted self-interviews (CASI). Participants will be assigned a unique study identification number (ID) that will be used to track data. Computer-assisted self-interviews are more effective than other tools for measuring sensitive and socially stigmatized behaviors. This mode of data collection eliminates interviewer bias, standardizes questionnaire administration, and reduces skip pattern errors. Using CASI, the participant responds to the questions using the computer keyboard or mouse. Selection of CASI for data collection decreases costs and error of entry, cleaning data, and publication lag, as well as enhances interviewer efficiency. The laptop computers the investigators use for data collection have been set up with two different log-in screens, one for participants and one for an administrator. The screen used by participants only contains the icon to access the CASI system. No other files appear or are available on this screen. The investigators access the CASI for participants by clicking the icon and filling in the assigned participant ID number (not participant name) completing all set up procedures. The investigator then provides a brief training on using the laptop and completing the CASI. As part of this training, the participant will complete a brief set of practice questions illustrative of the type of questions and the responses contained in the assessment. The investigator remains with the participant during the practice session to answer questions or to provide additional instructions. Participants will be encouraged to seek assistance, if needed, as they complete the interview. At this point, the interview starts and the participant completes the interview on their own. Once the participant completes the interview, he/she comes upon a screen instructing him/her to contact the investigators so that the file may be saved correctly.
Procedures for collecting physiological data: The investigators will conduct visual inspection of the affected areas and systematically count the number of acne lesions present on the face. At baseline and the follow-up assessment the investigators will also take high quality digital photographs of the affected areas that will be used to compute the degree of acne severity. The photographs will be identified exclusively by study ID and will be kept in a password protected file in a secure NSU computer. The Sebumeter® SM 815 sebum meter will be used to estimate the amount of sebum produced. The investigators will bring the mat tape of the meter in contact with the affected areas. This instrument uses a non-invasive probe placed on the affected area and the instrument then calculates the amount of sebum produced.

Change in Number of Acne Lesions Over the Course of 9 Weeks
The investigators will conduct a systematic count of acne lesions (papules and pustules) present in all of the affected areas of the face.
Time frame: Weeks 1,3,5,6,9
Change in the Amount of Sebum Produced Over the Course of 9 Weeks
The investigators will use the Sebumeter® SM 815 manufactured by CK Electronic to estimate the amount of sebum. The measurement is based on grease spot photometry. The mat tape of the Sebumeter® SM 815 is brought into contact with facial skin. It becomes transparent in relation to the sebum on the surface of the measurement area. Then the tape is inserted into the aperture of the device and the transparency is measured by a photocell. The light transmission represents the sebum content.
Time frame: Weeks 1,3,5,6,9
Change in Acne Severity Over the Course of 9 Weeks
The investigators will use the acne counts and the digital photographs of the affected areas to compute the acne severity level following the procedures established by Hayashi et al. (2008). The investigators will not print the digital photographs. The investigators will visually inspect the digital photographs and assign a preliminary severity score to each half of the face using the following classification guide: 0-5 papules and/pustules for mild acne; 6-20 for moderate acne, 21-50 for severe acne; and more than 50 for very severe. The investigators will examine each half of the face separately. The most severe classification obtained for either side of the face will be the assigned severity score.
Time frame: Weeks 1 and 9
Change in Dermatologic Quality of Life Over the Course of 9 Weeks
The investigators will use the Dermatology Life Quality Index (DLQI) developed by A. Y. Finlay and G. K. Khan (1992), one of the most widely used, dermatologic specific quality of life measures in the published literature to assess quality of life. The DLQI consists of 10 Likert type items; 9 of these items have 4 response categories scored from 0 to 3 with "very much" being "3" to "not at all" being "0". Item 7 "Over the last week, has participant's skin prevented participant from working or studying" uses dichotomous responses; where "yes" is scored as a "3" and a "no" requires answering an additional sub-question, "Over the past week how much has participant's skin been a problem at work or studying". Responses for this sub-question range from "a lot" coded a "2", to "not at all" coded a "0." The DLQI is calculated by summing the response to each question; the maximum score is "30" and the minimum score is "0". The higher the score, the lower the dermatologic quality of life.
Time frame: Weeks 1,3,5,6,9
Change in Social Anxiety Score Over the Course of 9 Weeks
Symptoms of social anxiety will be assessed using the Liebowitz Social Anxiety Scale (Liebowitz, 1987), one of the most widely used scales to measure social anxiety. It consists of 24 items designed to assess fear and avoidance in different situations that are likely to produce social anxiety such as going to a party or speaking in public. For each situation, participants are first asked to state how fearful or anxious they feel in that situation using a Likert scale that ranges from "none" (0) to "severe" (3). Then they are asked to state how often they avoid that same situation using a Likert scale that ranges from "never" (0) to "usually" (3). Responses are summed to create an overall anxiety score.
Time frame: Weeks 1 and 9
Change in Depressive Symptomatology Score Over the Course of 9 Weeks
The investigators will assess depressive symptomatology using the Hospital Anxiety and Depression Scale (HADS) (Zigmond and Snaith 1983), one of the most widely used screening tools to identify symptoms of depression, anxiety and emotional distress amongst patients being treated for a variety of clinical problems. It consists of 14 items, 7 of which assess generalized symptoms of anxiety and the remaining 7 assess depressive symptomatology. Although the specific wording of the item responses vary in accordance to the item, all responses are coded using a Likert format ranging from "0" to "3" where the most positive response is coded a "0" and the most negative response a "3". The maximum score for each subscale is 21; higher scores are reflective of more symptoms of anxiety or depression.
Time frame: Weeks 1 and 9
Change of Self-esteem Score Over the Course of 9 Weeks
Self-esteem will be assessed using the Rosenberg Self-Esteem Scale, one of the most widely-used self-esteem measures in social science research. It consists of ten items designed to assess respondent's self-satisfaction, self-respect and other general feelings about himself/herself. The response format is a four point Likert scale ranging from "strongly agree" to "strongly disagree". For items 1, 2, 4, 6, 7: Strongly Agree=3, Agree=2, Disagree=1, and Strongly Disagree=0. For items 3, 5, 8, 9, 10: Strongly Agree=0, Agree=1, Disagree=2, and Strongly Disagree=3. The scale ranges from 0-30, higher scores indicating higher self-esteem.
