Oily, blemish-prone skin is characterised by overproduction and over-secretion of sebum by the sebaceous glands of the skin (seborrhea) resulting in shininess, pimples and blemishes. The skin looks greasy with enlarged pores and uneven skin texture.
The sebum might clog the pores and attract bacteria (Proprionibacterium Acnes) causing whiteheads, blackheads (comedones) and frequent breakouts (acne). Other findings include abnormal keratinization (hyperkeratosis) and inflammatory reaction.
Treatment is complex and must address all aspects of this type of skin – hyperkeratosis, seborrhea, infection and inflammation.
