The Callus Softening Kit contains an active Callus Softening Tonic (100ml), a PH neutralizer (100ml), and all the tools you need to remove the dead skin cells from your heels – including a Pumice Stone, Foot Scraper, Dropper, and Latex Glove. The Elim Tonic is a keratolytic alkaline solution that softens the protein bonds of the skin which makes it easier for the dead skin cells to be removed from your feet, whilst the Neutralizer prevents dehydration. Therefore, this Kit is ideal for very dry and cracked heels and not only ensures effective results but a spa-quality experience within 10 minutes.
