Outcome Measures

Primary Outcomes (1)

  • Facial Irritation and Cutaneous Effects

    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.

    three weeks

Study Arms (1)

Tretinoin & Adapalene-Benzoyl Peroxide

EXPERIMENTAL

Tretinoin and Adapalene-Benzoyl Peroxide facial gels applied once daily in a split face model

Drug: Tretinoin Facial GelDrug: Adapalene/Benzoyl Peroxide Facial Gel

Interventions

A marketed facial gel containing Tretinoin 0.04% is applied to one side of the face daily for three weeks.

Also known as: Retin-A Micro Gel 0.04% Pump
Tretinoin & Adapalene-Benzoyl Peroxide

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

Also known as: Epiduo Gel
Tretinoin & Adapalene-Benzoyl Peroxide
