Detailed description: A study for Subjects with mild to moderate facial acne vulgaris. Subjects will be randomized to treatment with either DFD-03 (tazarotene) Lotion 0.1%, Tazorac (tazarotene) Cream, 0.1%, Vehicle Lotion or Vehicle Cream. During the 12-week treatment period subjects randomized to DFD-03 Lotion or Vehicle Lotion will use the study drug twice daily. Subjects randomized to Tazorac Cream or Vehicle Cream will use the study drug once daily in the evening. Subjects will be instructed to treat the entire face.

Safety assessments will include the investigator's assessment of local cutaneous tolerance/application site reactions on the face, vital signs and adverse events. Urine pregnancy tests will be performed for all female subjects. A physical examination will be performed.

Eligibility criteria: Inclusion Criteria:

At selected site(s), up to twelve subjects with acne lesions on the chest and/or back (including shoulders) in addition to those on the face will treat their chest and/or back (including shoulders) in addition to their face.
3. Inflammatory lesion count (papules and pustules) of at least 20, non-inflammatory lesion count (closed and open comedones) of at least 25 on the face including the nose, and no more than 2 nodulocystic lesions. This criteria is not applicable to the 9-11 years age group as long as subjects have an IGA score of 2 (mild) to 3 (moderate) at Baseline.

   Treatment with an investigational product or device in 30 days prior to Baseline.
3. Known allergic reaction to retinoids or tazarotene or any of the product ingredients.
4.
