everytime I go into a lush store, big blue is one of the first things I buy. Big Blue turns your water this turquoise-blue-ish colour that looks really similar to clean ocean water in Hawaii. my skin is always softer after I use big blue, and it always smells great. the salts in big blue act as a natural exfoliant, which I am all for. big blue is one of those bath bombs where the smell lingers on you for a couple of days. It smells incredible, and if you want to avoid all of the seaweed getting everywhere, just put it in some old pantyhose and you're set to go.
