How can I get rid of dark pores on my legs?

Maybe shaving? Some people do have darkening of the hair follicles following repeated shaving. Frequent, close-shaving causes minor trauma to the hair follicles and some folks can be sensitive to this, hence getting darker pores/follicles. If you stop shaving for an extended period of time, likely it will improve. Laser treatment /hair removal may help. Consult doc. Good luck.
