👉 A contracture is a medical condition that occurs when the skin on the lips, cheeks, and chin becomes tight and puffy. This can be caused by conditions such as rosacea or acne, or it may also be due to aging or other factors. The exact cause of contractures is not fully understood, but they are often associated with changes in the skin's elasticity and thickness. Contractures can affect the appearance of the lips and make them appear less natural.
