The oil on the surface of your skin is a product of sebaceous gland secretion and excretion, and its purpose is to protect your skin.
There are several reasons for oily skin:
First, high stress or irregular sleep patterns: Excessive stress or irregular sleep habits can lead to hormonal imbalances, disruption of bodily functions, increased levels of estrogen and testosterone, and excessive sebum production by the sebaceous glands.
Second, skin dehydration: When the skin lacks moisture, it undergoes “reflexive sebum secretion,” and hydrating and moisturizing can reduce sebum production.
Third, inadequate sun protection: Prolonged exposure to ultraviolet radiation can irritate the skin and stimulate excessive sebum production. It is important to use effective sun protection measures, such as applying lightweight sunscreen or using physical barriers like hats, masks, or umbrellas.
Fourth, increased temperature: The higher the temperature, the more active the sebaceous gland secretion. For example, during autumn and winter seasons, the skin may experience external oiliness and internal dryness. It is advisable not to use excessively hot water for bathing and to maintain an appropriate water temperature.
Fifth, excessive cleansing: Over-cleansing can lead to insufficient skin oil, which stimulates the sebaceous glands to produce more oil to protect the skin.
Sixth, excessive consumption of high-sugar and high-fat foods: Consuming excessive amounts of desserts, dairy products, oily and spicy foods, etc., can also increase sebum production.
In summary, oily skin is caused by a combination of internal and external factors. Adjusting lifestyle habits, maintaining proper cleansing and hydration, practicing sun protection, and following a balanced diet can help control oily skin.
