Final answer:
Seborrhea, also known as scale, in dermatological lesions is caused by excessive oil production or over-secretion of sebum by the sebaceous glands. Poor hygiene can worsen the condition, but it is mainly related to the activity of sebaceous glands and affects only the epidermis.
Step-by-step explanation:
The cause of scale/seborrhea in dermatological response to damage lesions is Excessive oil production. Sebum is an oily substance secreted by the sebaceous glands to lubricate and waterproof the skin and hair. However, when overproduced, it can lead to problems like acne and seborrhea, the latter being a condition characterized by flaky scales and greasy skin. Seborrhea can occur due to excessive secretion of sebum, and poor hygiene can exacerbate the condition. It does not necessarily occur due to a lack of moisture, an allergic reaction, or a bacterial infection, although these factors can contribute to other skin conditions.
Dermatological issues such as acne lesions are a result of inflammation when hair follicles become clogged with sebum, dead skin cells, and bacteria, fostering an environment for further irritation. Frequent washing can help decrease the amount of sebum on skin surfaces, which can reduce the severity of seborrhea. Additionally, seborrhea affects only the epidermis, which is the outermost layer of the skin.
