Nothing is more telling of a great summer than a sun-kissed finish, but when you haven't had time to make a weekend trip to the beach (or even sit by the pool, for that matter), getting a realistic-looking tan before your Labor Day festivities can be a tall order. We put together a comprehensive guide to getting your glow on, no matter the time constraints you're under. Case in point: The St. Tropez Express Self-Tanner ($44; sephora.com), which only takes one hour to develop a light tan, with a full-on bronzed goddess tone in just 3 hours. For those who want an even quicker option, Too Faced's Royal Oil Body Bronzer ($32; toofaced.com) imparts a rich tan that requires no upkeep, and can be applied as easily as your favorite body lotion.
