Negative effects of PM2.5 on skin health
The skin is the organ with the longest exposure to the external environment and with the largest area directly exposed to the air. It is also one of the organs with the largest direct exposure to PM2.5 and the first defense barrier of the human body. PM2.5 in air has the greatest impact on skin, especially facial skin.
There are more than 20,000 pores in the human facial skin, with a diameter of about 20-50 microns, these pores are the channel for the oil secreted by sebaceous glands to flow to the skin surface; while the diameter of PM2.5 particles in the air is less than 2.5 microns, which is much smaller than the diameter of pores, so the fine particles can enter the pores, hair follicles and sebaceous glands smoothly.
Studies have shown that airborne particles can increase sebum secretion, leading to acne, blackheads and other skin problems.
The higher the level of particles in the individual microenvironment, the higher the sebum level and the more easily the skin's oil and water balance is disturbed.
Avoiding airborne particle exposure during sleep is the key to good facial skin care
