Sun damage and aging cause the skin epidermis to thicken and a rim of cells are more likely to collect around individual pores that exaggerate pore diameter. This creates the illusion of the pores being larger than they really are. Enlarged pores are also known as open pores or large pores. Blackheads and enlarged pores often go hand-in-hand. Genetics, prolonged sun exposure, excessively oily skin, improper diet, poor lifestyle, inadequate cleaning routine, hormonal changes during puberty or menopause, all can be contributory factors to this condition. Microdermabrasion, laser resurfacing, chemical peels, retinoids, deep cleansing treatments help in reducing the size of the pores.
