Men have larger pores, increased sweat and lactic production than women. Increased sebum production after puberty accounts for longer lasting acne compared to women. Larger pores and increased sebum production allows for more congestion and blackheads. The increased amount of sweat produced and larger pores mean they are prone to bacterial infection and acne. Men do have more hydrated skin, probably due to the natural humectant effect of sebum and lactic acid.
Sweat production is more excessive in men and this can be localised to under the arm, in the armpit region.
