Final answer:
The damage to elastic fibers in the reticular layer contributes to sagging, wrinkles, aging, and stretch marks. The correct option is d.
Step-by-step explanation:
The reticular layer of the dermis is composed of dense, irregular connective tissue and contains elastic fibers. These elastic fibers provide elasticity to the skin, allowing it to stretch and return to its original shape. Damage to the elastic fibers in the reticular layer can contribute to sagging, wrinkles, aging, and stretch marks.
This connection between the reticular layer and esthetics is important for Hannah's model because it highlights the role of the skin's structure in maintaining a youthful appearance.
By including this information in her model, Hannah can demonstrate the impact of damage to elastic fibers on the aesthetic qualities of the skin.
