Air pollution influences skin ageing

Exposure to airborne particles influences skin ageing, according to a new study

Exposure to airborne particles influences skin ageing, according to a new study. The researchers assessed the effect of air pollution on ageing in 400 white women aged 70-80 years, using the score of extrinsic and intrinsic ageing.

Traffic-related exposure and exposure to background particle concentration were measured. The researchers then used linear and logistic regression analysis to assess their impact on ageing.

Air pollution, specifically from soot and traffic, was significantly associated with extrinsic skin ageing, particularly pigment spots on the forehead and cheeks. Particle pollution attributable to other sources, in areas without busy traffic, was also positively correlated with pigment spots on the face.
