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.
