Zanni Podospecial Corn and Callus Gel. This fluid gel works by reducing and softening calluses, giving the skin elasticity and softness. Visible results will be seen within three weeks of application: corns and calluses will be softened and skin thickenings reduced, thanks to the presence of alpha hydroxy acids with controlled acidity. Regular use helps prevent the formation of new calluses, giving the skin a healthy and pleasant feel. USE: apply to the affected area with a cotton swab, protecting the area with a plaster. Apply two or three times a week, avoiding contact with eyes, mucous membranes, and delicate areas. FUNCTIONAL SUBSTANCES: glycolic acid, polyquaternium-10.
