There are multiple forms of acne, dark spots, and skin blemishes, each with different causes, effects, and solutions.
A common cause of acne is clogged pores which occur when dirt, excess oil, and dead skin cells get trapped in your pores. Clogged pores typically result in blackheads and whiteheads, but it’s also possible you are dealing with sebaceous filaments which aren't a clogged pore at all.
