Aging plays into the gradual dehydration of your feet, causing the skin of your feet to look dry and flaky. Over time, the sweat glands in the feet lose their activeness and make the skin look dry, so we need to be wary of our hydration levels as we get older, podiatrist Dan Michaels, DPM. "To help prevent and treat common foot complaints, good home care is necessary," he emphasizes.
Dr. Michaels recommends filing your feet when they are dry and not wet because wet skin masks the areas that need to be addressed. Also, if you file with imprecision, you can over-file and weaken the skin tissues, which makes your skin more vulnerable to infection.
