Everyone has visible pores, but some naturally produce more sebum, leading to more pore spread. The sebum also oxidizes when it reaches the surface of the skin, causing the pores to become visible and spread. Pore size may increase with age because the skin loses elasticity. Regular cleaning and gentle abrasion removes the sebum from the skin surface, reducing porosity. Using mineral makeup that does not clog pores can help your skin look flawless. Through the pores, the body produces sebum and thereby softens the skin.
