Final answer:
Acne is caused by a combination of factors including blocked pores, excess oil production, bacteria, and hormonal changes.
Step-by-step explanation:
Acne is a skin condition that is caused by a combination of factors including blocked pores, excess oil production, bacteria, and hormonal changes. It is not directly caused by dietary indiscretions or uncleanliness, although these factors can contribute to the development and severity of acne.
For example, a diet high in refined sugars and carbohydrates can increase oil production and inflammation in the skin, which can worsen acne. Additionally, not properly cleansing the skin can lead to the buildup of dirt, oil, and bacteria, which can clog pores and contribute to acne breakouts.
However, it is important to note that acne is a multifactorial condition influenced by genetics, hormones, and other factors, so addressing diet and hygiene alone may not completely eliminate acne.
