We all know the great looking skin mantra: drink plenty of water, stay away from sugar, salt and alcohol and get plenty of rest. But we also know that these things aren't always possible. Late nights and early mornings are inevitable, so for times when sleep isn't an option, use these expert tips to help you look awake and refreshed. You'll have everyone fooled into thinking you got your required eight hours.

Celebrities and their entourages tend to work 20-hour days several days in a row yet mange to look fantastic. Do what they do. Elevate your head during sleep, drink tons of water, and minimize sugar and salt intake. -- makeup artist Taylor Babaian

If you wake up with dehydrated skin, then you're not doing the right nighttime routine. Before bed, make sure you cleanse, tone, and use a serum for any skin issues and a moisturizer for your skin type (find out what the best products for your skin are here). -- Marion Simms, founder of SkinSense Wellness Center

Don't pile on too much cream before bed; it'll just increase puffiness. Instead, use a lighter gel with peptides or botanicals. (Try SkinCeuticals Eye Renewal Gel, $30 or Yes to Cucumbers Eye Love Cucumbers Soothing Eye Gel, $14.99.) -- Simms

Next: What to do when you first wake up

Apply eye drops to help with any redness. My favorite eye drops are Rhoto (try Rohto V Cool Redness Relief, $6.79) for extra white eyes and a slight "wake up" effect. -- makeup artist Kristie Streicher
