Detailed answer

Cigarette smoke contains toxins and chemicals that can irritate the skin and increase inflammation. This can lead to a worsening of clogged pores by stimulating the production of excess sebum and trapping impurities in the pores. Additionally, smoke can decrease blood flow to the skin, reducing the skin's natural ability to detoxify and heal. Overall, cigarette smoke can contribute to the development and persistence of clogged pores, leading to more frequent breakouts and skin congestion.
