I received a box of no.7 skin care treats for christmas by a relative. Unfortunately i know it is a re gift from the year before (crimbo 2018). Would i be alright to start using it? Have run out of my usual stuff and I'm skint but don't want to aggravate my skin. I recently had my bathroom renovated and found some old.lush bathbombs. I tried them in the bath and they didnt seem to have fizzed as well as a brand new one. So just wondering about best before dates.........
