ITEC Beauty Specialist Practice Exam 2025 – All-in-One Preparation

Question: 1 / 400

What primarily causes intrinsic aging of the skin?

External environmental factors

Inherited genes

Intrinsic aging of the skin is primarily caused by inherited genes. This biological process is a natural part of aging, influenced by the genetic makeup of an individual. Factors like the rate at which collagen production decreases, the skin's ability to retain moisture, and the overall skin thickness are genetically determined. As people age, these factors lead to a reduction in skin elasticity and firmness, as well as the development of wrinkles and fine lines.

While external environmental factors, poor skincare practices, and dietary habits can significantly contribute to skin aging (often referred to as extrinsic aging), they do not dictate the inevitable changes that occur in the skin solely due to intrinsic aging driven by genetics. Understanding this distinction helps in recognizing the role of heredity in the aging process, which is essential for effective skin care and management strategies.
