Which skin cells are primarily affected in a client with protein deficiency and poor skin turgor?

In the context of protein deficiency and poor skin turgor, keratinocytes are the primary skin cells affected. Keratinocytes are the predominant cell type in the epidermis, the outermost layer of the skin, and they play a crucial role in maintaining skin integrity and structure. They are responsible for the production of keratin, a key protein that contributes to the skin's barrier function, protecting against dehydration and environmental damage.

When there is a protein deficiency, the synthesis and turnover of keratinocytes can be impaired, leading to compromised skin barrier function and reduced skin turgor, which is the skin's elasticity and hydration level. Poor skin turgor often manifests as skin that appears loose or sagging, and can also predispose the skin to injuries or wounds. Therefore, given the critical role of keratinocytes in maintaining the skin's structural integrity, they are directly impacted by nutritional deficiencies, especially those involving fundamental proteins essential for skin health.
