Final answer:
Cosmetics contribute to acne by clogging pores with oils and waxes, leading to blockages that can become infected by bacteria, causing inflammation and pimples. Individuals prone to acne should use non-comedogenic products and cleanse their skin regularly.
Step-by-step explanation:
Cosmetics can contribute to acne formation by clogging the pores of the skin. These products may contain oils, waxes, and other components that can mix with dead skin cells and sebum, which is the oil produced by sebaceous glands. When this mixture builds up, it can block hair follicles, leading to the development of whiteheads and blackheads. If bacteria such as Propionibacterium acnes infect these blocked pores, it results in inflammation, redness, and pimples.
Furthermore, certain cosmetics might not be non-comedogenic, meaning they do not prevent the clogging of pores. Therefore, it is essential for individuals who are prone to acne to choose products labeled as 'non-comedogenic' to help minimize the risk of breakouts. Daily cleaning with a gentle soap or cleanser can also help remove excess oil and dirt, thereby reducing the chance of acne development.
