The oil oozes and gives the skin
a greasy shine. It can be caused by heredity, diet, hormone levels, pregnancy
, birth control pills and hot and humid weather. Oily skin needs special cleansing with plenty of hot water and soap to prevent the pores from being clogged. Avoid harsh products that strip your skin of oil and encourage flakiness. They can cause a reaction known as reactive seborrhoea, where the oil glands work overtime to compensate for the loss of natural oils.
