Since ancient times people have relied on magnesium salts baths and rubs to help overworked muscles relax and recover, but they’re impractical for everyday use because of the mixing, mess and salty film. Sore+Tired products deliver magnesium sulfate to your skin in the same concentration as an Epsom salt bath or compress in an odorless, non-sticky, non-staining hydrogel formula you simply apply and go. Perfect for after shower or bath or before working out.
