Skin affected by seborrhoea feels unpleasant, and seems to get dirty quickly. The face appears shiny. Make-up may run off or cake and is difficult to apply. The affected area is often red, and greasy and scaly patches may develop; this is known as seborrhoeic dermatitis. Seborrhoea may also lead to acne.
