Air pollution, especially PM 2.5, can cause skin redness and long-term skin health issues, even with protective measures like sunscreen and masks.
According to a new study, air pollution with particulate matter (PM 2.5) can cause skin redness leading to long-term skin health issues (1

Researchers analyzed data from 472 participants in Taiwan and found a strong link between high PM 2.5 exposure and increased redness on the skin. The study suggests that harmful pollutants in the air can cause more severe damage to the skin than normal air pollution.
How Air Pollution Affects Skin Health
It highlights that air quality is an important factor for skincare and dermatology research. The research focused on two age groups. One group with adults aged 20-59 and the other group was over 60. Both groups showed a significant increase in skin redness when exposed to higher PM 2.5 levels. However, the older group experienced adverse skin redness compared to younger adults. This indicates that air pollution could be affecting skin differently across age groups, highlighting the need for targeted skincare solutions based on pollution exposure.
One of the key findings of the study is the role of sebum. In younger adults, higher sebum levels were linked to increased skin redness when exposed to PM2.5. This happens when pollutants in the air mix with skin oils, causing irritation and inflammation. The study also found that porphyrins, a natural compound on the skin were also involved in worsening redness among younger participants, making them more vulnerable to pollution-related skin issues.
Why Sunscreen and Face Masks Aren’t Enough
Even with protective measures like sunscreen and face masks, PM2.5 still had a significant impact on skin redness. It suggests that everyday skincare routines may not be effective in protecting against pollution damage. The ability of PM2.5 to penetrate deep into the skin and interact with natural oils raises concerns about its long-term effects, including chronic skin conditions and an increased risk of skin cancer.
Regular skin health screenings could help detect early signs of pollution-related damage. Using scientifically tested and approved skincare products designed to block PM2.5 penetration can help to prevent skin health.
