Don’t worry if you squeeze your nose and mysterious white stuff emerges. It’s just sebaceous filaments, made up of oil and dead skin cells. Your body uses this compound to lubricate and soften your hair and skin. Sebaceous filaments can plug your pores and cause adult acne. However, you shouldn’t squeeze your pores to get rid of it. Instead, gently wash your skin and apply proper skincare products. If needed, deep clean your pores with a face mask.
