1. Exfoliation

Start your preparations before the flight. Exfoliate your skin at home the day before, or on the morning of the flight use an exfoliating cleanser. This will get rid of the dead skin cells and make your skin more receptive to the moisturiser you'll need to apply while on the plane.

2. From the inside

your skin hydrated from the inside. Avoid alcohol while flying, as it will dehydrate you further. You don't need it anyway, and avoiding it will also help you sleep if you're on a late flight. Stick to drinking plenty of water and juice. Don't avoid drinking water so that you use the airplane bathrooms less.

3. Cleanse

If you're wearing makeup, take it off and cleanse your face properly. The most practical way when flying is to use wipes (I'm not a fan of wasteful disposable products, but they're certainly useful when traveling). Do use wipes that aren't too drying, however; you don't want to dehydrate your skin any further than it already is.

4. Serum

Facial mists sound refreshing, but won't be effective in the dry atmosphere of a plane. Instead, take a serum with you and apply before moisturiser. This will help to lock in the moisture and keep your skin nicely hydrated. You might need to apply the moisturiser more than once if you're on a longer flight; keep an eye on how dry your skin feels.

5. Movement

Obviously it's hard to move around on a plane, but getting your circulation moving will help your skin. When you get a chance, take a quick stroll around the plane. This will help stave off fluid retention. It's also helpful to avoid lowering your seat, and staying as upright as you can; lying back can give you eye bags as the fluid collects. If your eyes do get puffy, put an ice cube in a napkin and hold it there.

6. Hands

Don't forget your hands, which may also get dry and dehydrated. A good rich moisturiser will help here. If you use a simple moisturiser, it can double up as a lip balm, and you can also use it for your face (I love Nivea Crème for its multi-tasking qualities).

7. Balm

A balm like Elizabeth Arden's Eight Hour Cream can also be a very useful product to carry on a flight. If you forget to buy it beforehand you can easily pick it up at the airport. Products like this can be used on dry patches, as a lip gloss, to tame your eyebrows, or as a mask (if you don't mind looking a bit silly!). It's so versatile that it's a great space-saver in your baggage.

By keeping your skin well moisturised, you'll step off the plane looking good rather than having dry, dull and irritated skin. You don't need to fill your bags with a lot of products either. What's your favorite tip for keeping your skin happy while traveling?
