The Anatomy That Makes This Area Vulnerable
Periorbital skin, the tissue encircling the eye socket, has almost no sebaceous glands. That means it produces little to no natural oil, leaving it without the lipid barrier that keeps the rest of your face plump and protected. At roughly 0.5 mm thick, it is about four times thinner than the skin on your cheeks or forehead. Every blink, squint, and smile compresses and stretches this tissue hundreds of thousands of times a year. No other patch of skin on your face takes that kind of mechanical load continuously from childhood onward.
