Local Dermal Tolerability: Number of Participants With Dryness, Scaling and Erythema as Assessed by Investigator
Local dermal tolerability was evaluated by investigator in terms of presence and absence of dryness, scaling and erythema symptoms and its severity in the areas of body where medication was applied. These symptoms were assessed by using a 4 - point scale of 0 - 3, where 0 = none (no dryness, scaling and erythema) and 3 = severe (marked roughness, heavy scale production and intense redness). The higher score indicated severe symptoms.
Time frame: Week 12
Local Dermal Tolerability: Number of Participants With Stinging/Burning Symptoms as Assessed by Participants
Local dermal tolerability was evaluated by participants in terms of presence and absence of prickling pain sensation immediately after (within 5 minutes of dosing) and its severity in the areas of body where medication was applied (face). Stinging/burning symptoms were graded on a 4-point scale of 0 - 3 where 0 = none (no stinging/burning), 1 = mild (slight warm, tingling/stinging sensation; not really bothersome), 2 = moderate (definite warm, tingling/stinging sensation that is somewhat bothersome), 3 = severe (hot, tingling/stinging sensation that has caused definite discomfort). The higher score indicated severe symptoms.
