|Condition or disease||Intervention/treatment||Phase|
|Acne Vulgaris||Drug: Tretinoin Facial Gel Drug: Adapalene/Benzoyl Peroxide Facial Gel||Phase 4|
At the Baseline Visit, following satisfaction of entry criteria and screening procedures, all subjects will be applying two products to their faces, each on one side only. The side of the face receiving each product is randomly assigned. One group will use Retin-A MICRO Gel, (tretinoin) 0.04% Pump on the left side of the face and Epiduo Gel (adapalene .1% and benzoyl peroxide 2.5%), on the right side of the face daily for 3 consecutive weeks after washing with study-supplied facial wash. The other group will use the same products, but on opposite sides of the face for three consecutive weeks after washing with the same study-supplied facial wash.
Subjects will return to the study center every weekday morning for evaluation and application of both study products. Applications done on the weekends, will be done at home by the subject. At each visit the subject will be scored for cutaneous treatment effects by a blinded evaluator. At baseline and at the end of each week, subjects will be photographed and have chromometer readings.

Other Name: Retin-A Micro Gel 0.04% Pump
Drug: Adapalene/Benzoyl Peroxide Facial Gel
A marketed facial gel containing Adapalene .1% and Benzoyl peroxide 2.5% is applied to the other side of the face daily for three weeks

- Facial Irritation and Cutaneous Effects [ Time Frame: three weeks ]Scores on a scale were recorded each weekday. The scale for Erythema and Dryness was from 0=none to 8=severe (highest possible score is calculated as 8x5daysx3weeks=120). The scale for Burning/Stinging and Itching was from 0=none to 3=severe (highest possible score was calculated as 3x5daysx3weeks=45). The scores that were accumulated through the study for each treatment were then compared.
