Wendy's beauty stats: 40 - ish; naturally wavy highlighted hair with a mind of its own; blue / green eyes; dry skin with some visible laugh lines; dark circles not at all helped by a horrendous commute each day!
But applying repeated pressure (such as sleeping with the side of your face on a pillow) or muscle motions (such as laughing and squinting) against the collagen will promote its breakdown, eventually leading to visiblelines.
