This product WORKS! Amazing! I have super sensitive skin, so to find something that doesn’t irritate is a huge plus. It also has almost no scent, another bonus! This product doesn’t burn, sting, or have any cons as far as I can see. I have used it several times now, and it just keeps getting better. I have had calluses on my feet for years that no amount of filing, soaking, or any combination of products have cleared up, and this product has done it. I only wish I had taken before pics. Buy this, you won’t be sorry.
