Pores are the openings of the skin for hair follicles, each containing a sebaceous gland that happens to be bigger and more noticeable on areas of the face like the nose. The size of pores is largely based on genetics and they will only grow with age. In spite of what many products promise, it is impossible to shrink or close pores. However, following a certain skin care regimen will help to make the pores appear clearer and smaller.
Wash your face using a gentle cleanser every night before bed to remove the day's makeup, oil and grime; also wash before and after a workout to remove excess sweat. Consider using an electronic face brush once a day instead of your hands as it removes more dirt from the skin.
Apply a pore strip to the nose after a shower or cleaning your face. Wet the strip and wait until it is completely dry before removing it; this will extract any remaining dirt and debris.
Exfoliate daily to remove dead skin cells using an exfoliator with salicylic acid or alpha-hydroxy acids, such as glycolic. Sensitive skin may have a reaction to these ingredients, so proceed with caution -- spot check a small area before applying to your whole face.
Apply sunscreen with a sun protection factor of at least 15 to the face multiple times each day year-round. Understand that exfoliation will leave your skin more susceptible to harmful UV rays, which penetrate the skin and weaken the collagen that keeps pores small and tight.
Use only noncomedogenic moisturizers and makeup that will not cause clogged pores. Avoid those with heavier ingredients, such as mineral oil. Choose collagen-boosting ingredients like a retinol cream or Vitamin C moisturizer.
