Is sunscreen the best anti-aging product?

Sunscreen is widely considered the most important and evidence-backed anti-aging product available. Up to 80–90% of visible skin aging is caused by UV exposure, including wrinkles, dark spots, loss of elasticity, and uneven texture. No serum or cream can reverse the cumulative damage that daily unprotected sun exposure causes. A broad-spectrum SPF 30+ applied every morning outperforms nearly every other skincare investment for long-term skin health.
