Liquid keratolytic treatments use salicylic acid to gradually dissolve the thick, hardened skin that forms a corn. The liquid is applied directly to the lesion, softening the dense central core so it can shed and relieve pressure over time. This format allows precise application to irregular shapes or areas where pads don’t adhere well, such as between toes. Daily use is typically required, and care should be taken to avoid irritation of surrounding healthy skin. When paired with pressure-relief strategies like wider shoes or orthotics, liquid keratolytics can be an effective non-invasive treatment option for many corns.
