Final answer:
Acne is a bacterial infection often related to hormonal changes and can be exacerbated by stress. The primary causes are not linked strongly to excessive chocolate consumption or excessive washing.
Step-by-step explanation:
Regarding the statements concerning acne, it is accurate to claim that:
Acne is a bacterial infection.
Acne is a hormonal disease.
Acne may be caused by stress.
Specifically, acne is a skin condition that typically occurs in areas with numerous sebaceous glands, such as the face and back. It is often associated with the onset of puberty due to hormonal changes, such as increased androgens, which lead to an overproduction of sebum. This sebum, along with keratin, can block hair follicles, leading to the growth of Propionibacterium and Staphylococcus bacteria. This bacterial growth causes infection, leading to the well-known redness and potential scarring seen with acne. Stress may exacerbate acne, potentially by affecting hormone levels and immune response.
Contrary to popular belief, there is no strong evidence linking excessive chocolate consumption or excessive washing with the development of acne. While diet and skincare practices can affect overall skin health, they are not primary causes of acne.
