Shiny skin, also known as seborrhea, is a common skin condition that occurs when the skin produces excessive oil, resulting in a glossy or greasy appearance. It can affect people of all ages and skin types, but it is more common in those with oily or acne-prone skin.
Shiny skin can be caused by a number of factors, including genetics, hormonal changes, stress, and certain medications. It can also be a sign of an underlying medical condition, such as Cushing’s syndrome or polycystic ovary syndrome.
