Urban pollutants are small enough to get personal.
Microscopic air pollutants can be 20–40× smaller than the average facial pore, allowing them to infiltrate follicular openings and settle into the skin's structure.
Traffic pollution is linked to visible dark spots.
Traffic-related particulate exposure correlates with up to 20% more pigment spots on the forehead and cheeks.
Pollution can dry out your barrier fast.
High particulate matter exposure is associated up to 70% higher transepidermal water loss, a key marker of irritated dryness and barrier disruption.
This is not a niche problem.
Over one-third of the global population lives with PM2.5 levels above 35 μg/m³, a threshold 7× higher than the WHO's recommended annual guideline.
