Review: This is a classic, if not THE classic, Lush product. If I had to use one word to describe this, I’d say “refreshing”. It’s just like the ocean and has a stupifying deep blue color. Big Blue has a strong scent and has been known to make a couple of people headachey but it is totally invigorating and “spa-like” to me. And relaxing too. Big Blue ballistic has been a popular Lush item for years and years for a reason. The only down side is the small seaweed pieces to cleanup but if you really don’t like them you can put the ballistic in a nylon stocking or a giant teaball that you sometimes find in kitchen stores. I like the seaweed because it really is skin softening (so is the sea salt in Big Blue) and I have dry skin so my skin feels really good after a bath with Big Blue.
Notes: “Bubbling Under” was the bubble bar that Lush made to go with Big Blue. Lush’s “Enchanted Island” bath melt also has this same ocean/sea/lavender/lemon scent.
Lush Times 2006 description: Be aware that the Big Blue gives you the full Pacific Ocean experience, complete with strands of mineral rich seaweed (but stopping short of the actual fish). This bright blue Ballistic, topped with a crust of stimulating sea salt gives you a deep turquoise blue bath scented with balancing lavender and stimulating lemon oil to refresh your mind and body almost as much as a holiday by the warm ocean. Bear in mind that the Big Blue is a lot cheaper, there’s no jet lag and you don’t have to eat aeroplane food.
