Answer :
The hereditary condition characterized by excessive sebum production is Acne. Sebum is an oily substance produced by the sebaceous glands in the skin. When there is an overproduction of sebum, combined with dead skin cells and bacteria, it can lead to clogged pores and inflammation, resulting in the formation of acne.
Acne is a common skin condition that can manifest as pimples, blackheads, whiteheads, and sometimes more severe forms like cysts. It often occurs during puberty due to hormonal changes that stimulate the sebaceous glands to produce more sebum. However, genetics can also play a role in acne development, making it a hereditary condition in some cases.
In summary, Acne is the hereditary condition characterized by excessive sebum production, leading to skin issues like pimples and other types of acne lesions.
