What Causes Oily Skin?

Sebum is an oily substance that helps protect the skin barrier. When production is high, shine, enlarged-looking pores, and a greasy feel may appear, especially across the forehead, nose, and chin. Puberty and other hormone shifts can increase gland activity. Heat, humidity, stress, and products that irritate or over-dry the skin may also make oiliness more noticeable. Oily skin can occur without another disease, but it may accompany [Acne](/conditions/acne/) or [Hormonal Acne](/conditions/hormonal-acne/). Flaking or redness around the nose, eyebrows, or scalp can point toward [Seborrheic Dermatitis](/conditions/seborrheic-dermatitis/).

Wash gently with lukewarm water, avoid scrubbing, and choose non-comedogenic moisturiser and sunscreen. Blotting papers can reduce surface shine without repeated washing. Do not layer many harsh drying products, because irritation can worsen discomfort and make the routine harder to maintain. A clinician can match treatment to acne, inflammation, or persistent oiliness; prescription options such as [Isotretinoin Treatment](/treatments/medical-dermatology/isotretinoin-therapy/) require careful medical assessment and monitoring.

Arrange a dermatology assessment if oiliness comes with painful or deep spots, scarring, marked redness, persistent scale, sudden hormone-related changes, or symptoms that do not improve with gentle care. Seek prompt advice for rapidly worsening inflammation, spreading swelling, or eye involvement.

Could hormones, medicines, or another skin condition be contributing to my oiliness? Which cleanser, moisturiser, sunscreen, or acne treatment fits my skin? How long should I try the routine before we reassess it?
