Detailed answer

Blackheads can be caused by a combination of factors such as excessive oil production, the build-up of dead skin cells, and clogged hair follicles. Not using a facial scrub alone is not the sole cause of blackheads. Regular exfoliation can help remove dead skin cells and prevent clogged pores, but it is not the only solution. Other factors like hormonal changes, genetics, and certain skincare or cosmetic products can also contribute to the formation of blackheads. It is important to have a well-rounded skincare routine that involves cleansing, exfoliating, and using appropriate products for your skin type to effectively manage and prevent blackheads.
