Social media has a huge influence on skincare routines, often promoting complex do-it-yourself regimens aimed at keeping a youthful appearance. But dermatologists say many of these viral products are unnecessary, even if they feel nice, and some can cause more problems than they fix. Real experts recommend a simple routine including a gentle cleanser, moisturizer, and sunscreen with at least SPF 30. Protecting your face from the sun's UV radiation is crucial. Retinol creams and chemical exfoliants can help smooth out wrinkles, but should be used carefully. And those really expensive products? Many share the same ingredients as the much cheaper ones.

Lip balm can soothe chapped lips, but some people may be allergic to its ingredients. For those few, the products can sting instead of soothe. Dermatologists recommend looking out for flavorings, preservatives and fragrances in popular lip balms because they can cause allergic reactions. Other ways to soothe dry lips include covering the mouth with a scarf, drinking water and avoiding licking your lips too often. If your lips are still dry after trying lip balm, consider seeing a dermatologist to learn more.
