Unclean skin looks shiny, rough and oily to the touch. There is little colour and the pores get dilated. This is a very common skin type among adolescents, and acne lesions or acne scars are typical. Those who have unclean or greasy skin have sebaceous glands that secrete a lot of sebum, the substance that gives skin a greasy and oily appearance.
For this type of skin, proper products are needed that do not overuse the skin and help normalize sebum production through deep hydration and counteracting the proliferation of microorganisms: detergents, scrubs and specific creams help purify and hydrate unclean skin.
