The liquid is packed with fruit extracts which polish away the dead skin cells. The results are by no means instant, however you will feel a tingly sensation for a while afterwards and feet feel really cool.
After a few days all the dead skin (as gross as it sounds), seems to dissolve and shed off. Much like sunburn but it seems on a larger scale. Using a clean sponge to gently buff the feet after a good soak seems to speed up the process.
For anyone with seriously dry, cracked feet these socks are a Godsend and I urge you to try. There’s no endless hours of foot filing and every hard bit of skin literally melts away. I cannot recommend these enough to anyone with problematic feet.
