Q

How is skin affected by aging?

A

the epidermis thins and flattens = (loss of protective barrier).
- the dermis experiences a loss of connective tissue (collagen) = risk of shearing and tearing.
- the subcutaneous layer decreases = less cushioning from physical injury
- decrease in amount of sweat and sebaceous glands = skin is dry, less thermoregulatory response.
- psychological impact of a loss of youthful appearance, linked to self-esteem Compounded by culture, beliefs, media, social norms and roles.
