Are pore strips bad for your skin? They can help temporarily improve black dots on the nose. These aren’t blackheads, but rather little clusters of retained hairs. This is called trichostasis spinulosa & pore strips help remove the little clusters of hairs. Pore strips can be irritating, so don’t overdo it. Otherwise, they can be useful for this common cause of black dots on the nose. #porestrip #porestripnose #porestripremoval #dermatologist
