To make pores as invisible as possible, keep them clean. Use a gentle cleanser in the morning and evening and after you sweat. A product that's too harsh will dry out your skin and trigger an undesirable response: an overproduction of oil. Scrubbing doesn't help empty those tiny openings, either -- stick to gentle exfoliants that help clear out dead cells. You can also try a pore-minimizing cream designed to increase the production of glycosaminoglycans, which tackle the problem of inelastic skin [source: Crawford].
There are pricier treatments you can try at a doctor's office, including microdermabrasion and chemical peels. Both clean out pores and can make skin look smoother, but there are also side effects involved -- and a hefty price tag. Try a gentle at-home regimen first.
