17 Jul 2023 --- Scientists from the US and Denmark have discovered that certain skin-protective compounds, like squalene, go beyond their functions and may help improve air quality. They found that ozone in the environment reacts with the oils and lipids on our skin, particularly squalene, which results in the creation of our own “personal oxidation fields of protection.” According to their recent publication, simply having both people and ozone present indoors can produce significant levels of the “powerful” hydroxyl (OH) radicals, which are highly reactive molecules that play a vital role in cleaning the air and protecting human health.
