UK based mother and daughter combo, Hilary McMurray and Shelley Martin, had a simple idea - a fake tan that didn't smell and wouldn't stain clothes. After numerous formula trials, they found the perfect tanning blend and in 2008, the Tantastic Brand was born. About. Tantastic is not just a self-tan, it's a fashion accessory for women (just like you) who live fast, spontaneous lives and need a tan to match: so that you can spend less time preparing to go out and more time actually having fun. Tantastic is instant and fast drying.
