Carol’s Question…My Mario Badescu skin lotion
The Left Brain’s Reply:
We all know that certain environmental factors, such as the ultraviolet radiation in sunlight, can cause skin damage. But what about air pollution – is it bad for your skin? To answer that question we refer you to a study recently published in the International Journal of Cosmetic Science (2006. 28. 349-357) entitled Effects of Environmentally Realistic Levels of Ozone on Stratum Corneum Function.
Testing pollution on human skin
Using a specially designed environmental chamber, researchers exposed panelists’ skin to ozone, which is the primary oxidant in photochemical smog. They found that ozone does have some effect: not only does it reduce the level of vitamin E in skin but it also kills off some of the normal skin bacteria. However, these effects were small and did not have a significant impact on any of the enzymatic processes that really control skin health.
Pollution effect is minimal
They theorize that the effect of pollution is minimal because of one of three reasons:
- Skin’s natural anti-oxidant defense system protects the skin
- Conditions aren’t right for ozone reactions that would cause more damage
- Ozone just isn’t able to penetrate deep enough into skin to cause any real problems
UV is much worse than pollution
Regardless of the reason the researchers conclude that at best ozone exposure only induces a moderate level of oxidative stress on skin and doesn’t produce any measurable clinical response. (That means that instruments may be able to detect differences but you couldn’t see or feel them.) In the opinion of the researchers, exposure to UV radiation is much more damaging to skin than ozone pollution.
The Brains Bottom Line:
While the data does show a minor effect from pollution, it’s not really a significant problem. Until someone presents data that contradicts this study, it looks like any lotion claiming to protect your skin from pollution is just marketing hype.

THank you for this post! I am sort of a sucker for these undo-pollution damage claims and it’s good to know the realities behind it.
I wonder sometimes if people actually read your posts when they complain that you laud synthetic personal care products constantly, and are obviously in the pocket of some big-money company. You make so many posts like this where you deflate claims by synthetic product manufacturers
Clearly, if you were in the pay of some of these companies, you’d do nothing but gush about products like this.
I always feel that pollution is damaging to my whole body and skin suffers as the biggest organ because of it
Your skin’s pretty good at keeping stuff out — it’s much less at risk than your lungs, which pollution definitely does really take a heavy toll on.
I wasn’t sure how accurate these claims where. I won’t be quite as lured by suggestions of protection against pollution anymore.
Does the carbon black, soot and CO emissions harm the skin?
