Oily skin is recognisable as it can look shiny and greasy and it can often lead to breakouts and enlarged pores.
Oily skin can also mean that make-up does not stay on well.
As with any skin type, there can be all sorts of reasons for it, and genetics, stress and hormonal changes will always play a part.
Oily skin comes about as a result of excess sebum which is released from the sebaceous glands beneath the skin and hangs on the skin.
Sebum is made from fats, and we do not want to eliminate it from our skin entirely, as it helps to protect and moisturise the skin and prevents it from becoming irritated.
However, when we get too much of it, pores can become clogged and create spots, blackheads and acne.
This extra moisturisation does have one good point though, as the suppleness means that wrinkles are kept away for longer!
The T-Zone is the area of greatest concern for oily skin types. This is the forehead and nose, creating that t-shape across your face.
This area has more active oil glands that may produce excess sebum and it can be the case that this area is oily whilst the rest of the face is normal or dry, creating combination skin.
