Detailed answer

To prevent your skin from becoming dull while traveling, there are a few key steps you can take. Firstly, make sure to keep your skin well hydrated by drinking plenty of water and using a moisturizer suitable for your skin type. Additionally, protect your skin from the damaging effects of the sun by applying a broad-spectrum sunscreen with at least SPF 30 regularly throughout the day. Remember to reapply after swimming or excessive sweating. It's also important to cleanse your skin thoroughly every evening to remove any dirt, pollution, or makeup accumulated during the day. Finally, consider incorporating antioxidant-rich products into your skincare routine to help combat the oxidative stress caused by traveling. These steps will help maintain a radiant and healthy complexion while on the go.
