Epsom-It soothing muscle lotion brings the power of epsom salt directly to aching muscles. This concentrated lotion, also available in a convenient rollerball, delivers targeted relief. Fortified with Arnica, this topical magnesium cream is more concentrated than a traditional epsom salt bath soak. It penetrates deep under the skin for maximum soothing action where it is needed most. Enjoy the therapeutic benefits without the tub.
