Brief Summary:
The purpose of this study is to determine the dermal sensitization potential of azelaic acid pre-foam formulation.

Condition or disease Intervention/treatment Phase
Healthy Drug: azelaic acid pre foam formulation Drug: Vehicle pre foam formulation Drug: Water Phase 1

Detailed Description:
In an induction phase a three times weekly exposure over three weeks will be performed, followed by a resting phase. In a following challenge phase single exposure will be performed again and potential skin reactions observed. If skin reactions occur an optional re-challenge phase may be performed.
