A coworker I was traveling with kindly came to the rescue with a mini bottle of the Avène Thermal Spring Water. I immediately understood why the facial mist had earned its place as a prestigious skincare staple. That night, I ordered a travel-friendly and full-sized bottle to come home to, and I haven’t ventured out without it since. The mineral-rich skin savior is made with only two ingredients: thermal spring water bottled at the source and nitrogen, according to the brand. As it journeys through the Cévennes Mountains in the South of France, the water becomes organically infused with skin-loving ingredients like magnesium, calcium, silicates, and microflora. The neutral pH also contributes to maintaining balance and providing comfort to irritated skin. To buy: $19; aveneusa.com. To use, you don’t need to shake the canister, just hold it upright and a few inches from your face to mist. The instructions say to wait a few minutes, then pat into your skin, but my face drinks this stuff right up in seconds. Avène suggests using its Thermal Spring Water spray on all skin types to relieve sunburns and post-shaving irritations and to replenish moisture. It’s literally a splash of invigorating hydration at your fingertips. Keep it in your fridge to spritz on after an intense workout or routine yard work for an even greater refreshing boost.

(Seriously, I failed to pack nice dress shoes for a work trip once or twice, but I’ve never forgotten my stash of Thermal Spring Water for any plane ride). As someone who’s constantly testing out new skincare products, it’s nice to rely on a very basic and effective product like Avène’s Thermal Spring Water facial mist whenever my complexion cries out for moisture.
