Whether you can see it or not, urban pollution is part of everyday life.
From vehicle emissions and industrial pollutants to wildfire smoke drifting hundreds of miles and airborne particulate matter, our skin is exposed to environmental stressors every time we step outside.
Research over the last decade has shown that pollution doesn't just affect our lungs—it also affects our skin.
Studies published in the Journal of Investigative Dermatology, JAMA Dermatology, and the International Journal of Women's Dermatology have linked long-term exposure to airborne pollution with increased oxidative stress, premature skin aging, pigmentation changes, weakened skin barrier function, and increased skin sensitivity.
One of the primary culprits is particulate matter (PM)—microscopic particles suspended in the air.
• PM10 (≤10 µm) can settle on the skin's surface.
• PM2.5 (≤2.5 µm) is even smaller and is commonly associated with wildfire smoke and combustion.
Pollution also contains reactive gases and compounds that contribute to oxidative stress.
Together, these pollutants generate free radicals that can overwhelm the skin's natural antioxidant defenses and contribute to visible signs of aging over time.
Pollution Is Becoming Part of Everyday Life
Urban air pollution isn't limited to major cities anymore.
Traffic emissions, construction dust, wildfire smoke, secondhand smoke, industrial emissions, and seasonal air-quality events can affect communities across North America. Even on days when the sky looks clear, air quality may not be ideal.
That's why dermatologists are increasingly recognizing environmental protection as an important part of a modern skincare routine.
A Smarter Way to Protect Your Skin
Pour Moi created Smoke Alarm Drops with Climate-Smart® Environmental Defense Technology™ to help intercept pollution where it first meets your skin.
The adaptive hydration shield helps reduce pollutant adhesion while Swiss botanical defense ingredients and MossCellTec® help support the skin barrier and maintain hydration in polluted environments.
Because pollution levels change throughout the day, the AI Drop Finder™ provides personalized recommendations based on your local air quality in real time, helping you use the right number of drops—from one to three—when your environment calls for extra protection.
From Our Scientific Advisor
"Urban pollution has become an everyday part of modern life, and protecting the skin barrier should be just as routine as cleansing or moisturizing. I recommend my patients add Smoke Alarm Drops to their moisturizer daily. The AI Drop Finder makes it simple by adjusting protection based on real-time air quality."
