We've asked the experts for their best tips on how to do everything to get the most out of your wedding day hair and makeup. Whether you're planning to look totally natural or go all-out glam, here's how to:

Be extra careful -- once it's smudged, you don't want to make it worse, or you'll have to start over from scratch. Scott Miselnicky, executive director of global product development at Clinique, suggests moistening a cotton swab with makeup remover and gently dabbing the mistake until it's completely gone. Go slowly so you don't take off too much!

Choose a hairstyle that will bring out your best feature, explains Jamal Hammadi, celebrity hairstylist and founder of Hamadi Beauty. "For an updo, placing the style between the top of your ear and the top of your eye (like a high ponytail) will enhance the shape of your eyes, while placing it lower (like a chignon) will put the focus more on your lips and neck," he says.

Right before the wedding is not the time to try out a new skincare regimen. No matter how tired you are, make sure you stick to your cleansing schedule and remove your makeup before you go to bed. If you really need more ammo, try a mask that contains salicylic acid, but make sure you test it at least six weeks before the wedding so a possible reaction will be long gone by the time you walk down the aisle.

It only takes two tools to do this right: a quality brush and a makeup sponge. First, squeeze or pump foundation onto your hand and use a brush to "paint" it on your face for overall coverage. Then, use a sponge to blend away any streaks and to remove excess buildup.

Lots of brides like to amp up their look for the reception, and a deeper lip hue is a great way to do it. "Using a brighter lip color will always make your teeth look whiter; a big plus on your wedding day!" says Stila makeup artist Sarah Lucero. Keep the rest of your features relatively neutral and your eye makeup soft, not severe.

Miselnicky suggests applying a small amount of Vaseline onto your teeth to keep lipstick from winding up there. "Also, gently blot your lipstick with a tissue after you've applied it to remove any excess," he says. "Believe me, the groom will be happy!"

"Always try to wash and rinse your hair with cool water, which will help maintain its natural moisture and prevent your hair from drying out," Hammadi says. Follow with a frizz-fighting product that will boost your protection level. Try Hamadi Shea Spray ($18, beautyhabit.com) --spritz it onto wet hair after showering, and then again after you've styled to keep things smooth.

Waterproof mascara is a wedding day must-have. "I use waterproof on everyone involved in the wedding party because you never know who will tear up!" Lucero says. For lower lashes, she recommends applying mascara with a flat eyeliner brush rather than the mascara wand. "This trick prevents smearing under your eyes, which can make you look tired," she explains.

It might be tough, but Diane Berson, an assistant attending physician at New York-Presbyterian Hospital, says getting plenty of sleep is the key (and not just the night before the wedding). "Sleep with your head elevated on a pillow to reduce puffiness, and try not to rub your eyes," she says. It's also a good idea to use an eye cream that brightens as well as hydrates.

You may not have time to redo your makeup before the reception starts, but you should give yourself a quick once-over in order to make sure you stay looking great (after all, nearly every second of the reception will be photographed!). Makeup expert Francis Roman of Butterfly Studio says to skip blush and eye shadow (too risky). Instead, apply another layer of lip color and blot your T-zone with a sheet of oil-removing paper. Then run a makeup sponge or a cotton swab beneath your lower lashes to remove any mascara or eye shadow that may have smudged or fallen beneath them, and you're good to go.
