Space Girl first and foremost smells amazing. It smells so much like my favourite childhood sweet - palma violets which is probably why I gravitated towards it in the shop. Lush have claimed the main ingredient to be Grapefruit oil, but I other ingredients include Almond Oil. This bath bomb contains popping candy and I found it actually took a while to fizzle out completely, which I liked.
As you can see in the photos, the bath water turns a lovely lilac colour. Whilst for the most part I can only sing praises to this product, I did find that the water made my skin feel squeaky clean as opposed to other bath bombs which tend to moisturise the skin. But this is definitely personal preference and I wouldn't let this put you off giving it a smell next time you're in Lush.
