As we age, our skin begins to thin and starts producing less elastin, collagen and hyaluronic acid. The result is thinner skin that is less firm with reduced elasticity. All of this makes us more vulnerable to wrinkles.
There are three different kinds of wrinkles: dynamic wrinkles, static wrinkles and wrinkle folds.
Dynamic wrinkles are the wrinkles caused by repeated smiling, frowning, squinting, etc. With each muscular contraction, the skin around our eyes and mouth and on our forehead bunches together. Over time, this leads to crow's feet, frown lines, and forehead lines.
Static wrinkles are present when we are not forming facial expressions. With age, our skin starts to lose its structure and volume. This means that our face isn’t able to spring back to its resting state after making facial expressions—resulting in static wrinkles.
Wrinkle folds are most often due to the sagging of the underlying facial structure. The most common wrinkle folds are the deep grooves between the nose and mouth called nasolabial folds, known more simply as “smile lines.”
The signs of wrinkles
Immediately visible when you open your eyes wide or have a surprised look on your face, these horizontal creases are often the first wrinkles that will go from being dynamic to static. Because they’re found on the forehead, they’re among the most noticeable facial wrinkles.
Much like forehead wrinkles, frown lines—which are the creases that form between your eyebrows when you frown—are among the first signs of aging. They too begin as dynamic wrinkles, but with time become static wrinkles. The biggest complaint from people who have noticeable frown lines is that—as the name suggests—they look unapproachable.
These wrinkles—also known as nasolabial folds—are the large wrinkles or folds that run vertically from the bottom of the nose to the corners of the mouth. They’re called smile lines because they’re most prominent when smiling or laughing. Every year our skin produces less and less elastin, collagen and hyaluronic acid, resulting in more noticeable smile lines.
These dynamic wrinkles form when you squint and smile. They begin as smaller lines which begin at the outside corner of your eyes and spread out towards the temples. They get their name because they form the shape of crow’s feet.
Another facial wrinkle that appears around the mouth, these wrinkles run vertically from the corners of the mouth down the sides of the chin. They typically become noticeable after other types of wrinkles. All wrinkles are unwanted, but marionette lines in particular are the target of treatments because they can give the face a permanent scowl.
