Forget expensive anti-aging creams β the most powerful product for youthful skin is sunscreen. UV damage is the #1 cause of premature aging, including wrinkles, pigmentation, and loss of elasticity. Daily SPF prevents long-term skin damage, whether you're indoors, outdoors, or under clouds. Choose a broad-spectrum sunscreen with at least SPF 30, and reapply every 2β3 hours.
