Callifuga floppy disks with plaster - duroni from Colpharma are pads with patches that protect and remove calluses from the sole of the foot or heel quickly and painlessly. Easy to wear with shoes, they protect against friction and pressure. Salicylic Acid is a substance with great keratolytic properties (it dissolves the keratin that forms the thickening of the skin) that, if used in a high concentration (40%), is effective against calluses and warts. Urea is a substance that is used profitably in skin and nail care. It is particularly effective in nail mycoses where used in high percentages (40%), by modifying the pH of the skin, it selectively softens the parts contaminated by the microorganism, facilitating their cutting and removal. It is recommended to submerge the duron in warm water for about 10 minutes. Dry carefully. Remove a floppy disk from its holder and apply it directly to the duron. The calligraphic diskette must be applied to the duron. Place the protective patch over the disc. Change the protective patch and disc every day for at least 2/3 days.

Do not use on inflamed, cracked skin, with small cuts or on skin not affected by the callus. Keep out of reach of children. External use, Do not reuse. Store in a cool, dry place.
