Wrinkles Encyclopedia

In the skin, extracellular matrix is composed from hyaluronic acid and other sulphated agents combined with collagen and elastin. As skin ages, the supportive components of the skin are gradually destroyed. The skin becomes drier and thinner and starts to sag. In addition, wrinkles appear facial muscles stiffen with age. Thus, areas subjected to repeated movements facial expression, such as the forehead and around the eyes and lips, become wrinkled.

There are three types of facial wrinkles: dynamic wrinkles, static wrinkles, and wrinkle folds.

Dynamic wrinkles:
Dynamic wrinkles are caused by the contraction of muscles that are attached to the overlying skin. Each muscle contraction causes the skin to tighten, thus forming lines. The most common locations for dynamic wrinkles are frown lines between the eyebrows, horizontal lines across the forehead, and lines extending from the outer corners of the eyes.

Static wrinkles:
Static wrinkles are due to the lack of elasticity of the skin caused by sun damage, smoking, genetics, poor nutrition, or from prolonged dynamic wrinkling. Static facial wrinkles are visible regardless of muscle contraction; they stay even when the muscles are not contracting.

Wrinkle folds:
Wrinkle folds are often due to sagging of the underlying facial structures, most notably causing deep grooves between the nose and mouth known as the nasolabial folds or smile lines.

Individuals differ, but generally, facial wrinkles and folds are formed over the years. The names given to the wrinkles and folds in each area are labelled. Facial lines and features that can be corrected using hyaluronic acid injections include:

kraehenfuesse_01Periorbital lines
radiate outward the corners of the eyes (crow’s feet).
stirn-falten_01Forehead wrinkles
(worry lines) come in two types: vertical and horizontal. The vertical wrinkles usually occur between the eyebrows, just above the nose. Horizontal wrinkles occur between the top of the eyebrows and the hairline.

glabella-falten_01Glabellar lines
