Detailed answer

Blackheads are primarily caused by clogged pores due to the overproduction of sebum, dead skin cells, and bacteria. Although toners can help remove excess oil and unclog pores, they are not the only solution to prevent blackheads. Proper skincare routine, which includes cleansing, exfoliating, and moisturizing, plays a significant role in preventing blackheads. Cleansing removes dirt, oil, and impurities from the skin, while exfoliating helps to remove dead skin cells and prevent clogged pores. Moisturizing keeps the skin hydrated, preventing the overproduction of sebum. Additionally, maintaining a healthy diet and avoiding pore-clogging products can also contribute to blackhead prevention. While a toner can be a helpful addition to a skincare routine, it is not the sole determinant of blackhead formation.
