This was a double-blind, randomized, three-treatment, parallel study conducted at three locations with a single investigator. Normal, healthy male and female children and adults (i.e., ages 12 to 40 years) with at least Grade 2 (i.e., mild severity) acne vulgaris were treated on the full face once daily for 84 days with the Tretinoin Gel 0.05%, Brand (tretinoin) Gel 0.05%, or Gel Vehicle. Acne lesions were graded by a single blinded observer at screening and at Weeks 0 (i.e., baseline), 2, 4, 8, and 12 at each location.~The assigned study treatment was self-applied topically once daily for 84 consecutive days. Scheduled study visits included:~Visit 1 (Baseline Visit, Day 0)~Visit 2 (First Interim Visit, Day 14)~Visit 3 (Second Interim Visit, Day 28)~Visit 4 (Third Interim Visit, Day 56)~Visit 5 (Forth Interim Visit, Day 84)~A window of ± 4 days was considered acceptable for each scheduled visit following the Baseline Visit. Subjects were admitted into the study if they had a clinical diagnosis of acne vulgaris and if they met the inclusion/exclusion criteria. During the study visits, the following procedures were performed:~Counts of inflammatory, non-inflammatory, and nodulocystic lesions~The Investigator's Global Assessment (IGA)~Assessment of application site reactions Safety was assessed by the monitoring of AEs and documenting signs and/or symptoms of application site reactions.
