Short of staying hermetically sealed in an air conditioned home or office, there is simply no way to avoid the perils of hot weather and the havoc it wreaks on our skin, hair and makeup. Sweat. Frizz. Sunburns. Did we mention sweat? Summer beauty -- oxymoron? Discuss. Yet, somehow, even in the dog days of summer, celebrities manage to look dewy-fresh and natural, whether they're in formalwear on the red carpet or cavorting in bikinis on a beach vacation. They seem to have all of the answers to our burning summer beauty questions: 'How can I make a sunhat work during a pool party without looking like a frumpy old lady?' Or, 'How do I wear bright lipstick with an equally loud outfit and not look crazy?'. Celebrities (or their stylists) show us how to pull off prints and how to make no-makeup makeup seem chic. They're our go-to beauty and style experts.

So, what are their beauty secrets to getting (and staying) gorgeous this summer? Of course braids are forever a summer beauty essential and sunscreen is the beauty must-have, but we want to know what the A-listers are doing to look fab, feel great and stay gorgeous this season.

Here, seven stars reveal their favorite summer beauty tips and the products they use to keep summer beauty bummers at bay. These celebrity beauty tips range from Katy Perry's extensive skin care routine (hint: it's not using Proactiv) to Lauren Conrad's melt-proof method of staying chic all summer long.
