What to do if your skin is prone to acne

Our skin is not just one type, there are many types of skin, and the most troublesome one is oily skin. This type of skin is not only greasy, but also produces a lot of oil. This is because the oil secretion on the inside of the skin is vigorous. Coupled with unhealthy lifestyle and bad eating habits are the main causes of oily skin. So what should we do if oily skin is prone to acne?

Usually, we can divide the skin into three basic types: oily, neutral and dry according to how much oil the skin produces. Oily skin has a darker color, large pores, coarse skin texture, high sebum secretion, oily and shiny skin. It is more tolerant to external stimuli and not prone to aging and wrinkling, but is easily affected by pollution and prone to acne.

How much oil the skin produces actually refers to how much sebum the sebaceous glands secrete. Generally speaking, men's skin is oilier than women's skin and has larger pores. In addition, the secretion and excretion of sebum is also affected by other factors:

① Temperature. When the skin temperature rises, the amount of sebum increases (sebum secretion increases by 10% when the skin temperature rises by 1°C). The melting point of sebum is about 30°C. Sebum is liquid at high temperatures, semi-liquid at medium temperatures, and solid at low temperatures. Therefore, when the skin temperature rises, the viscosity of sebum decreases, the resistance pressure that inhibits sebum excretion decreases, and sebum excretion is promoted. Therefore, the skin tends to be oily in summer and drier in winter.

② Humidity. The humidity on the skin surface can affect the secretion and diffusion of sebum. When the skin surface is moist, sebum is easy to emulsify and spread; when the skin is dry, the secretion and diffusion of sebum become slow.
