If you are applying self tanning mousse at home, prep your skin like you would for a spray tan. Exfoliate properly with a good mitt the day before, do shaving and hair removal the day before, and shower at least four hours before application. Use less product on hands, feet and elbows, blend with a soft brush, and wear loose clothing after. At Personal Tanner in Brisbane, Karina recommends proper prep and smart application for a more natural-looking self tan.
