Detailed answer

Blackheads, or open comedones, are caused by the accumulation of excess oil, dead skin cells, and bacteria within the pores. While using a face oil can help moisturize and nourish the skin, its absence alone does not directly cause blackheads. Other factors that can contribute to blackheads include genetics, hormonal changes, certain medications, excessive sebum production, and poor skincare routine. It is important to maintain a consistent cleansing routine, exfoliate regularly to remove dead skin cells, and use non-comedogenic products to prevent the formation of blackheads. Additionally, incorporating a well-balanced skincare regimen that includes gentle cleansing, exfoliation, and moisturization can help manage blackheads effectively.
