All about wrinkles - Expression Lines and fibroplastic contractions

When we furrow our brows, or make some other kind of expression, the repeated pulling or traction exerted on the skin by subcutaneous facial muscles creates tension in the very place where expression fines form, This tension affects the dermal, or inner, layer of the skip by way of the collagen fibres upon which fibroblasts are anchored.

Although these lines help us to convey to others a range of emotional states, some facial expression lines always seem to connote fatigue or anger, even if those appearances do not represent how we are feeling.
