Question: 1 / 400

What is the main cause of acne?

Excessive oil production

Clogged pores

The main cause of acne is primarily attributed to clogged pores, which occur when excess oil, dead skin cells, and bacteria accumulate in the hair follicles. This condition creates an environment conducive to the development of acne lesions, such as pimples, blackheads, and whiteheads. While excessive oil production, bacterial infection, and hormonal changes can all contribute to the formation of acne, clogged pores are fundamentally the initial trigger in many cases.

When the sebaceous glands produce excess sebum (oil), it can mix with dead skin cells. If this mixture is not exfoliated adequately, it leads to the obstruction of hair follicles. The blocked pores create a breeding ground for bacteria, which can further exacerbate the issue. Therefore, understanding that clogged pores are a pivotal aspect in the development of acne helps in ensuring effective skin care and treatment strategies.
