Why Sunscreen Is the Only Anti-Aging Product You Really Need
Every anti-aging serum, cream, and treatment on the market promises to turn back the clock, but none of them work as effectively as a broad-spectrum SPF applied daily. Roughly 80 to 90 percent of visible skin aging — fine lines, dark spots, sagging, and uneven texture — is caused by UV exposure rather than the natural aging process. This means that skipping sunscreen essentially cancels out the benefits of every other product in your routine, no matter how expensive. Dermatologists recommend at least SPF 30, reapplied every two hours if you're outdoors, and applied even on cloudy days since UV rays penetrate clouds and glass. Pairing sunscreen with antioxidants like vitamin C in the morning offers extra protection against environmental damage. If you only commit to one beauty habit this year, make it this one.
