As we age, the skin gradually becomes thinner, drier, and loses elasticity due to a decline in collagen and elastin production. This reduces the skin’s ability to protect and renew itself, leading to the development of fine lines, creases, and wrinkles.

Facial expressions and repeated muscle movement also contribute to wrinkle formation. These are known as dynamic wrinkles—lines that appear when facial muscles contract during expressions such as smiling or frowning. Over time, if left untreated, dynamic wrinkles can evolve into static wrinkles, which remain visible even when the face is at rest.
