Acne starts in hair follicles due to numerous reasons. Sebum production rises, the follicle is blocked, acne-causing bacteria are present, and inflammation occurs. Sebum and dead skin cells can clog hair follicle pores, allowing acne-causing bacteria to thrive.
Genetic predisposition, hormonal swings, medications, food, skincare, and lifestyle factors including face mask use all affect acne development. Together, these factors cause and worsen acne.
