An 85-year-old patient is concerned that the bones in their face have become more noticeable. What explanation should the nurse give to the patient?

Dermal atrophy in the elderly results from a decrease in fibroblast activity and the loss of dermal collagen and elastin. The depletion of subcutaneous adipose tissue leads to a loss of the protective "cushioning" over bony prominences. Reduced sebaceous gland secretion leads to chronic xerosis. These structural changes combine to make the underlying facial skeleton more apparent. A. Diets low in protein and high in carbohydrates may cause enhanced facial bones: While severe protein-energy malnutrition (marasmus) can cause muscle wasting and sunken features, this is not the standard physiological reason for increased bone prominence in the general aging population. Normal aging processes occur regardless of a standard diet. B. Facial skin becomes more elastic with age: This is scientifically incorrect. Aging leads to a significant decrease in skin elasticity and tensile strength. The skin becomes more redundant and prone to sagging (ptosis) rather than becoming more taut. It is the loss of underlying volume that makes bones visible. C. It is probably because the patient has excessive sun exposure on the face: Photoaging (dermato-heliosis) accelerates skin wrinkling, pigmentary changes, and the risk of neoplasia. While it contributes to the overall aged appearance and thinning of the skin, it is not the primary cause of the loss of subcutaneous fat. D. It is probably due to a combination of factors related to aging, such as decreased elasticity, subcutaneous fat, and moisture to the skin: This is the correct scientific explanation. The redistribution and loss of facial fat pads, combined with the thinning of the dermis and epidermis, allow the contours of the skull and facial bones to become more defined and prominent.
