This research is being done to find out the safety and efficacy of two acne creams, Effaclar and Benzaclin when used twice daily with a topical retinoid. Effaclar and Benzaclin are FDA approved for the treatment of acne.
There are many products on the market to treat facial acne. The medication that this study will be evaluating, Benzaclin and Retin-A have been approved by the FDA and is available by prescription, Effaclar is an over the counter product. This study will hopefully recognize a treatment combination that is effective in reducing acne vulgaris in adults 18-50.
