We asked a former flight attendant to share her travel skin-care musts — and they're all under $50

Let's start with this 16-piece toiletry kit, perfect for downsizing bigger bottles of the stuff you already love into TSA-approved minis. It contains four leakproof silicone squeeze bottles, four screw-top jars, two spray bottles, product scoopers, a funnel, a brush, labels and a clear bag to carry them in.

"This cleanser leaves my skin feeling refreshed and clean, but not overly dry," says Barnwell, who uses it every day while traveling. Cetaphil is a favorite of thousands of Amazon users, and it's suitable for a wide variety of skin types thanks to its gentle, hydrating formula. Oh, it's also among our picks for the best face wash you can buy.

Hydration is the name of the game when it comes to travel-ready skin, especially when flying. "The air in airplanes is so dry," Barnwell says. She adds: "The idea of liquid lotion originally blew my mind, but with this product, my skin stays hydrated all day and there's no residue, even when mixed with other facial products. I love, love, love how light this is. It's worth the price — a little goes such a long way!"

Though she wants to keep her skin quenched, Barnwell doesn't want to feel weighed down by the skin-care products she chooses. This "makeup-gripping" sunscreen — one of our beauty editor's faves as well — is "very light wear on the face," she says. "You'll still feel bare-skinned!" Sunscreen is important for summer travel, and this SPF 40 favorite will keep your skin protected without feeling greasy or sticky.

"Light, fresh and helps tone my skin," Barnwell raves. A good toner like this one should be the first step in your skin-care routine, helping to exfoliate and rebalance skin while locking in that all-important hydration. 

Barnwell uses this product once a week to help her skin recover from environmental contaminants amassed over days of nonstop travel. The peel reveals more radiant skin after each use, and it also helps improve skin texture thanks to the included salicylic, lactic and glycolic acids — all aim to leave skin softer and smoother.

Barnwell dubs this "the perfect bedtime moisturizer," adding that since it's not heavy, it "leaves my skin soft and moisturized but not prone to breaking out like other nighttime moisturizers." The gel consistency adds extra quenching goodness, leaving skin more hydrated after your beauty sleep.

This treatment deeply exfoliates skin, helping smooth fine lines and boost natural radiance. Getting a glow on the go sounds good to us! "This is one of my favorite skin-care products, period. The results speak for themselves — my skin was so clear within days of my first application of this," Barnwell raves.

Don't sleep on finding a good eye cream. Barnwell is obviously a fan of Laneige's Water Bank line for keeping skin moisturized on the go, and this cream targets eyes specifically to keep peepers perfect even after hours of tiring travel. "It really helps to combat puffy, tired-looking under eyes," she notes.
