Zim’s Max Crack Creme Original Liquid Formula is 100% natural. It is made with Arnica & Myrcia Oil. It was developed by a pharmacist 60 years ago to help cement workers who were complaining of dry, cracked skin on their hands and feet. Zim’s now has a loyal following from many construction workers, mechanics, healthcare and factory workers, helping them alleviate their dry, cracked skin. Zim’s Max Crack Creme is made in the USA and is not tested on animals. The original liquid formula is just that – liquid. For some reason this surprised me when I first opened the bottle! It has a light herbal scent. A little goes a long way – we had to be careful so we didn’t get the liquid everywhere! The liquid formula is recommended for use at night, in combination with the daytime formula.
