Uh, Should You Stop Using Retinol While Traveling? The Answer May Surprise You

Using a retinol during the winter is already a delicate dance, as cold, dry air can exacerbate some of the ingredient's bemoaned side effects. But for those traveling during the holidays, it involves even more guesswork: A new destination, after all, can add so many new variables, like humidity, type of water, and perhaps dry, airplane air—all of which can affect how your skin reacts to the beloved ingredient. Is it best to just, gasp, leave it at home? 

Let's say you live in a chilly climate and are spending the holidays somewhere tropical—your skin may take a hot minute to get used to the humidity, pollution levels (or lack thereof), and overall traveling woes, like the dry air on planes. Same goes for those who live at sea level jetting off to a mountain climate—your skin may need to adjust to the drier air. "I don't believe it's worth the downtime that may come with the climate adjustment," Ciraldo continues. 

The tap may even play a role, especially if you're traveling to an area of hard water. "Hard water tends to make skin drier and more sensitive, and it can leave your skin reddened," Ciraldo once shared with mbg, especially if your skin barrier is already compromised.

And speaking of tropical vacations: "If you are planning a winter beach getaway, I'd leave the retinol home since you can develop sun sensitivity from it," she adds. Remember: Retinol can increase photosensitivity1, causing a rash or sunburn-like reaction when you're exposed to sunlight. "This is why it's recommended to use retinoids in the evening and protect your skin with a moisturizer with sunscreen during the day, so you get all the benefits and minimize the side effects," board-certified dermatologist Keira Barr, M.D., tells mbg about the vitamin A derivative.
