You've got oily skin, so why would you put more oil on skin that is already as oily as it is? As contradictory as it sounds, olive oil stops the skin from producing excessive oil of its own, making it perfect for oily skin.
Over-active sebaceous glands produce too much sebum, which makes the skin oily and can result in block pores and nourishment for bacteria. Olive oil in itself dissolves oil well, and will do so without drying it out or leaving your skin feeling oily or greasy. Olive oil has been used for centuries to moisturise and cleanse the skin.
So why exactly should you use olive oil on your skin? There are many reasons:
Olive oil is high in oxidants, one of which is hydroxytyrosol which is extremely rare and can slow down the aging process by stabilising the cell plasma membrane.
If you suffer from oily skin, it may sound odd to apply more oil on it but on the contrary, regular treatment of your skin with oil sends a message which makes your skin produce less oil of its own. Makes sense doesn't it?
One great thing about olive oil is that it is extremely gentle and non-irritating, perfect for sensitive skin. It leaves your skin hydrated, soft and supple. Extra virgin olive oil is the least processed and also contains the the highest nutrient value, hence this type of olive oil is best for delicate skin.
After going ahead with your regular night facial routine which should consist of makeup remover (if you wore makeup), cleanser/exfoliator and moisturiser, pour some olive oil in your palms and massage it into your skin with your fingers. Don't worry about your skin looking too oily at first, just let the oil dissolve into your skin.
Don't stop on your face: go ahead and use it on other parts of your body that may need some moisturising.
