GlossaryPore Size

diameter of skin's tiny openings affecting oil and hair

Pore size refers to the diameter of the tiny openings on the surface of the skin, known as pores. These pores are the outlets for hair follicles and sebaceous (oil) glands. In a biological context, pore size can influence skin health, as larger pores may be more prone to clogging and acne, while smaller pores can indicate less oily skin. For professionals, understanding pore size is crucial for diagnosing skin conditions and recommending appropriate skincare treatments.
