Menthol description

Derived from peppermint, menthol can have the same sensitising effect as peppermint on skin. Despite its documented ability to sensitise skin, menthol is included in a surprisingly large number of products. Unfortunately, the cooling, refreshing sensation menthol causes is direct evidence that your skin is being sensitised, not soothed.
