Sunscreen Daily: the most proven anti-aging step

Sunscreen Daily — the most proven anti-aging step. UV exposure causes most visible skin aging and raises the risk of skin cancers over time. Daily broad-spectrum SPF 30 blocks the majority of UVB rays and slows photoaging. Apply about a nickel-sized amount to the face and a shot-glass amount to the body for full coverage. It nudges the same cellular pathways that premium formulas are marketed for. Trials report lower inflammatory cytokines, flatter glucose curves and better nitric oxide availability. In month one, count how often you did it — never how hard. For most adults, make SPF the last step of your morning skincare routine, even on cloudy days. The best plan is always the one you actually follow.
