TYPES OF WRINKLES

According to a study published in the International Journal of Cosmetic Science (2006), researchers at the University Hospital of Liege, Belgium determined that there are four distinctly different types of #wrinkles that you’ll (eventually) have to face.

  1. Atrophic Crinkling Rhytids – fine lines on the face that are almost parallel to each other.

They show up on different areas of the face and body but tend to disappear when skin is stretched transversally (this just means they shift when your body posture changes). These wrinkles are associated with loss of elasticity.

  1. Permanent Elastic Creases – Crease lines in the skin that become increasingly permanent over time, especially with sun exposure.

Where they occur: They show up most frequently on on the cheeks, the upper lip and the base of the neck.

  1. Dynamic Expression Lines – Wrinkles that are caused by facial muscle movement.

Where they occur: Commonly referred to as frown (or smile!) lines and crows feet.

4.Gravitational Folds – As the name implies, these lines are due to the effects of gravity and become increasingly obvious as skin begins to fold and sag.

Where they occur: The location of these wrinkles is related to the thickness of skin. While I would have thought this means that thicker skin shows more folds, surprisingly the researchers said that a plumper face may show fewer gravity folds than a lean face.
