Effects of PM 2.5 on the Skin
PM 2.5 (Particulate Matter smaller than 2.5 microns) is an air pollutant that directly affects skin health. Due to its small size, PM 2.5 particles can penetrate through pores and enter the skin, causing the following issues:
- Triggers inflammation and irritation – PM 2.5 particles induce skin inflammation by stimulating the release of inflammatory cytokines, leading to allergic reactions and skin redness.
- Accelerates premature aging – PM 2.5 generates oxidative stress, which depletes collagen and elastin, resulting in wrinkles, sagging, and dull skin.
- Stimulates abnormal melanin production – These small particles can trigger excess melanin production, causing hyperpigmentation, dark spots, and melasma.
- Weakens the skin barrier – PM 2.5 damages the lipid barrier, leading to dry, dehydrated skin that is more sensitive to irritants.
- Promotes acne and clogged pores – Toxins in PM 2.5, such as heavy metals and hydrocarbons, stimulate sebaceous glands, leading to clogged pores and acne.
