I applied Iodine on the fresh cracks around my toenails because they hurt like a wound does. It dried up the following day so I did not apply anymore.Days after that I had a foot spa in a salon to remove the dead skin. The cracks lessened somehow. But then yesterday I got a new crack on my right big toe and the old cracks on my heels are starting to show. I really do need to moisturize my feet to prevent recurrence. Coconut oil can do that right? Any brand would do I hope.
