Looking great while away from home doesn't mean packing everything but the bathrooms sink! To get more mileage out of fewer products, see what beauty experts never leave home without.

Arrive gorgeous and refreshed, thanks to versatile makeup and smart multitaskers for your skin.

It hydrates skin, acts as a foundation, and some provide SPF. Jessica Wu, a Los Angeles dermatologist, suggests Dior Hydra Life BB Creme SPF 30.

New York City makeup artist Carmindy loves long-lasting Blinc Mascara, which enhances each lash.

An oil-rich one locks in the moisture that plane air zaps. Fresh Sugar Rose Lip Treatment SPF 15 softens and adds a pink tint.

Dark circles? Dab on illuminating Bodyography Canvas Eye Mousse.

With 18 colors for eyes, lips, and cheeks, Laura Mercier Glamour Wardrobe flatters day or night.

Load up on daily skin-care and hair musts, then toss in a few troubleshooters to tackle travel specific concerns.

A pore-friendly mist shields from head to toe without stickiness. Jill Waibel, a Miami dermatologist, likes Replenix Sheer Physical Sunscreen Spray SPF 50+ (dermstore.com).

Go for one with shea butter or nut oils, like Tocca Crema da Corpo in grapefruity Cleopatra, which treats parched spots and doubles as shaving cream.

Dallas aesthetician Joanna Czech freshens while out and about with Malin + Goetz Pill Towels; wet one in water, and it expands to a 9-by-11 inch washcloth. 

Zen out in your suite's tub: Lollia's Sea Salt Sachet in Wish, a vanilla scent, is good for four dips.

To banish blemishes, Waibel reccomends salicylic acid, like that found in VMV Hypoallergenics Red Better Spot Corrector.

An airy whip, such as Clinique Moisture Surge Intense, will never create an oil slick.

To lift T-zone shine without shifting makeup, Wu relies on Clean & Clear Oil Absorbing Sheets (sold at drugstores).

It holds updos in place and keeps down flyaways, yet combs out for easy restyling. Sharon Dorram, a colorist in New York City, likes Phytolaque Soie (beautybar.com).

Dorram dusts roots with Dr. Hauschka Body Silk to absorb oil, boost volume, and create beachy texture. Swept on skin, it also sets makeup.

The argan oil in Josie Maran Argan Hot Oil Self-Heating Hair Treatment rehydrates sun-dried hair on contact. Bring one ampule for each week you'll be traveling (sephora.com).

Hotels often install these in bathrooms—which, of course, get damp—but Wendy Iles, a hairstylist in Paris, takes a B.Y.O. approach. "You can't get sleek hair in a humid space," she says. Plug the powerful fold-and-go Brookstone Ionic Dual-Voltage Travel Hairdryer into a drier spot in your suite.

Many in-room freebies are harsh on color, so Iles totes gentle products. Skip heavy bottles and opt for the mini packets in Oribe's Beautiful Color Travel Set.

A drop pre-blow-dry combats humidity, and a coat before swimming repels chlorine and sun damage. Try Bumble & Bumble Color Minded UV Protective Styling Balm.
