Oily skin is simply the result of the overproduction of sebum. Under the skin pores, there are sebaceous glands that produce natural oils called sebum. This helps keep your skin hydrated and healthy. However, oily skin forms when your skin produces an excess amount of sebum, resulting in an increasing amount of build-up, which leads to acne, clogged pores and inflammation.
Genetics: Oily skin tends to run in families. If your family has a history of oily skin, you’re likely to have overactive sebaceous glands, too.
Weather: People living in hot, humid climates are more likely to have oily skin. That’s why people often complain of oily skin during the summer. Also, during this time, the oils on your face will be more likely to mix with sweat and clog your pores.
Wrong skincare routine: Oily skin can be brought on by using the wrong skincare products for your skin type. Washing your face or exfoliating too often strips away too much of the oil from your skin. This can cause your sebaceous glands to go into overdrive producing even more oil to make up for the loss.
The key to preventing oily skin is bringing the overproduction of sebum under control. For example, there could be an imbalance in the skin’s hydration, causing it to overproduce sebum when you wash your skin too much. In this case, to control the amount of oil you produce would require having a set skincare routine. On the other hand, when oily skin is caused by genetics or hormones, it’s can be challenging to prevent it
