"I'm a big believer in hydration when traveling, so I always tend to pack MDNA The Rose Mist, $120. I find it refreshing and awakening. It smells amazing (always a great perk) and gives my skin a dewy glow. It's formulated with mineral-rich thermal waters of Montecatini, Italy, which are anti-inflammatory and therapeutic to the skin. It's great for anyone with any skin type who needs a quick boost on the go."
