Shaving and waxing at least 8 hours BEFORE being spray tanned is recommended since both remove the top layer of skin and opens pores. Applying a spray tan after shaving or waxing can give a freckled appearance in those areas. Shaving/waxing AFTER a spray tan will accelerate the exfoliating process and fade the tan faster giving it a streaky or patchy look. Always use a sharp razor so you remove the hairs only and not the tan.
