Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Adapalene gel 0.3%<br>All odd numbered subjects will receive treatment to the left arm. The untreated arm will serve as an intrapatient control and will be evaluated separately from the treated arm for signs of purpura. | Drug: adapalene gel 0.3%<br>* A pea size drop of Adapalene gel 0.3% will be applied to the odd numbered subjects on the left dorsal hand & extensor forearm. A pea size drop of Adapalene gel 0.3% will be applied to the even numbered subjects on the right dorsal hand & extensor forearm.
