Final answer:
The reticular layer is the layer of the skin that contains both interwoven bundles of collagen fiber and the protein elastin, and is responsible for the strength of the skin. It is composed of dense, irregular connective tissue and contains collagen fibers for structure and elastin fibers for elasticity. Collagen injections and Retin-A creams can help restore skin turgor and repair the dermis.
Step-by-step explanation:
The reticular layer, which is the lower layer of the dermis, is composed of dense, irregular connective tissue. It contains collagen fibers for structure and tensile strength, as well as elastin fibers for elasticity. The reticular layer also binds water to keep the skin hydrated.
Collagen injections and Retin-A creams can help restore skin turgor and repair the dermis.
