Decades of Squinting
01The Muscle That Contracts 10,000 Times a Day

Every time you squint, laugh, smile, cry, or focus on a screen, the ring of muscle around your eye — the orbicularis oculi — contracts. That muscle folds the thin skin around your eye the same way thousands of times per day. Each fold lays down a microscopic crease. By 55, those creases are permanent. The muscle itself tightens and refuses to release, pulling your skin inward and downward. This is why crow's feet and under-eye crinkles deepen faster than any other line on your face — and why no serum, no matter how expensive, can relax a muscle that's been contracting for five decades.
