What is the main cause of acne?

1. Excessive moisture

2. Bacterial infection

3. Blockage of pores

4. Allergic reactions

The correct answer is: Blockage of pores

The primary cause of acne is the blockage of pores. When hair follicles become clogged with excess oil, dead skin cells, and sometimes bacteria, this blockage creates an environment conducive to acne development. This process leads to inflammation and can result in the formation of pimples, blackheads, and cysts. While factors such as bacterial infection, excessive moisture, and allergic reactions may contribute to the severity or expression of acne, they do not serve as the foundational cause. In acne, the initial blockage of the pores is critical, as it sets off the other processes, such as potential bacterial growth, that worsen the condition. Therefore, understanding that pore blockage is the main trigger helps in addressing acne effectively through appropriate skincare and treatment methods.
