There are two types of enlarged pores that resemble each other but are totally different. Your enlarged pore is caused because you are lacking an adequate balance of oil and moisture in your skin. If there is not enough moisture in the skin the surface of the skin will have tiny dents in it resembling an enlarged pore. If these tiny indenting sections in the surface of the skin arrange in a line, you have what looks to be a wrinkle. Many of the cosmetic manufacturers have campaigns that promote diminishing tiny lines and wrinkles with rejuvenating creams and moisturizers.
Some companies suggest exfoliating the area before applying the moisturizers to impede penetration.
If the skin is very dry I would suggest applying very light pressure because the skin is fragile and will bruise easily. Increasing your daily intake of water will certainly help your entire body to hydrate. The other enlarged pore is caused by over-active oil glands that produce excessive sebum that becomes clogged in the pore and stretches the pore. If this situation goes unattended the sebum will harden and cause Blackheads. Removing the clogged oil and dirt from the pore on a regular regime of facials will allow the pore size to continue to shrink because of the elasticity in the skin.
