What causes the open pores or caters on face???!!!

Skin changes: Enlarged pores of the skin, particularly of the face can be the result of dirt, debris or oils of the skin. These can clog or block the pores, which should naturally be open, to help protect the skin and keep it hydrated. Daily washing of the face, avoiding strong soaps, can keep the skin healthy and clean with lessening of clogged pores. If no improvement, seek a Dermatologist for further help
