First, pay attention to diet.
A very important reason for acne is that improper diet leads to the increase of facial oil, such as foods that are too spicy, high in calories and irritating, and some foods that are easy to get angry. Try to eat less. Eat more foods that clear away heat and toxic materials, such as pitaya, bitter gourd and other cool fruits and vegetables.
Second, control oil and replenish water.
Oil control is essential for all oily skin. Moreover, lack of water will aggravate skin oil production, so if you want to control oil, you must replenish water. Pay attention to daily moisturizing and don't use alcoholic products.
Third, don't be too clean.
Some people think their faces are oily, so it is actually wrong to wash their faces several times a day. Under normal circumstances, washing your face twice a day is enough. Excessive cleaning will destroy the self-purification ability of the skin, leading to more serious oil production.
