Skin looks greasy and shiny because it produces too much oil which is called sebum by scientists.
Prone to blackheads, whiteheads and pimples.
PRODUCT SUGGESTIONS
Use a mild or gentle facial wash daily. Avoid fragrant soaps and harsh cleansers.
Wash your face gently. You can stimulate your oil glands by washing too hard and ending up with a more oily face.
Apply an oil-free and lightweight moisturizer after shvaing. The proper moisturizer or aftershave should make your face look dry and solve that greasy look.
Avoid any product that stings or overly dries your face. If you over-dry your face by washing it too much, your face compensates by producing too much oil.
