After you have soaked your feet in a foot bath, you put parafin cream on your feet - put plastic bags on your feet and then put your feet on a foot vibrator with heat for about 15 minutes MAX and it softens your feet. Then you should put white, cotten socks on. White so the light gets through, cotten so the air gets through. It does make the feet soft.
I bought a foot parafan machine. I also have a separate Conair foot bath. You can get them at most drug stores or discount stores. They're pretty cheap.
I get a pedicure once a month. And once a week, I give myself a foot parafin to keep them soft.
Why pay someone $15 when you can buy a parafin machine for about $25 or less?
Doesn't make financial sense.
