Detailed answer

Blackheads are primarily caused by excess sebum production, clogged pores, and dead skin cells. While using a moisturizer is important for maintaining the overall health of the skin, it does not directly cause blackheads. However, using a moisturizer that is too heavy or comedogenic (pore-clogging) can potentially contribute to the formation of blackheads. It is essential to choose a non-comedogenic moisturizer that suits your skin type and does not block the pores. Additionally, using a cleanser and exfoliating regularly can help prevent and treat blackheads by removing the excess oil, dirt, and dead skin cells that can clog the pores.
