Even though it is hard to permanently shrink large skin pores, there are always ways to reduce large skin pores.
Cleaning up the pores debris, excess oil, and bacteria, will significantly improve their appearance. When cleaning the pores, use a low-strength topical medication, or other antioxidants, this can help the skin increase collagen and elasticity.
Exfoliating can also help to minimize the large pores appearance. Facial scrub, spa treatment, or microdermabrasion treatment can help to remove the surface layer of the skin.
