Detailed answer

Blackheads are primarily caused by excess oil, dead skin cells, and bacteria clogging the pores. While using too many skincare products can potentially irritate the skin and lead to inflammation, it is not a direct cause of blackheads. However, certain skincare products that are heavy or comedogenic (likely to clog pores) may contribute to the formation of blackheads in some individuals. It is important to choose non-comedogenic products and maintain a consistent skincare routine to prevent and treat blackheads.
