Dr. Pimple Popper on the Biggest Skin-Care Myths and Her Favorite Products

SLMD Skincare Retinol Resurfacing Serum ($30)

Dr. Lee stresses that nothing permanently shrinks your pores where pimples live, but there are agents you can use to help keep them clean from any debris, like this retinol serum from SLMD Skincare. Formulated with retinol and vitamin A derivatives, this nighttime treatment helps improve the appearance of hyperpigmentation and encourages exfoliation to prevent clogged pores. "You can use retinol or Retin A at night, which is great to help minimize pores. If you want something more drastic, sleep in a freezing room or go on a cold plunge — that will shrink them for sure."
