Hi Stacy,
I do not use Biofreeze but I do have very dry skin on my toes and underside of my feet. I have been using Eucerine Complete Repair lotion for dry, rough skin. I try to use this everyday, applying in the evening before bed. If I miss a day I can usually feel a difference
when I wear shoes or socks. The lotion is fragrance-free and contains 5% Urea. So far I have not experienced any problems with this lotion, just some relief from the awful dryness.
