Detailed answer

Blackheads are caused by the buildup of oil, dead skin cells, and bacteria in the pores. While using a serum may have benefits for the overall health and appearance of the skin, it does not directly cause blackheads. Blackheads form when the pores become clogged, and this can happen due to various factors such as excessive sebum production, improper skincare routine, and certain hormonal changes. To prevent blackheads, it is important to cleanse the skin properly, exfoliate regularly, and maintain a consistent skincare routine that suits your skin type. While a serum with the right ingredients may help in improving skin texture and minimizing the appearance of blackheads, it is not the sole determining factor in their formation.
