Corns
Conditions
Brief summary
This is a prospective, randomized, controlled, open-labelled investigation to assess performance and safety of Orkla Corn Plaster in subject with corns. The hypothesis is that there is an improvement in the size of corns at day 28 compared to baseline.
Interventions
COMBINATION_PRODUCTOrkla Corn Plaster with salicylic acid
Each participating subject will receive Orkla Corn Plasters for usage up to 28 days, or until corn resolution whichever comes first. Subjects will be instructed to change plasters daily.
DEVICEOrkla Corn Protector
Each participating subject will receive Orkla Corn Protector for usage up to 28 days, or until corn resolution whichever comes first. Subjects will be instructed to change plasters daily.
