Smog, car exhaust, and cigarette smoke – these are amongst some of environmental pollutants we are surrounded by daily (and perhaps over-exposed too if living in an urban area). We’re all aware of how these forms of pollution can cause damage to our health internally, but how can they affect us externally?
Redness, skin damage such as wrinkling and hyperpigmentation, and various skin issues can result from exposure to such pollutants. This is because air pollutants can generate free radicals, which are known for being one of the biggest skin aggravators. The most common of these are Reactive Oxygen Species or ROS. These attack macromolecules on the skin such as membrane lipids, proteins, and DNA, which can lead to skin health disorders.¹ It has been postulated that these particles can serve as carriers for organic chemicals and metals that are capable of localizing in mitochondria and generating ROS.²
Luckily for our skin, seaweed has natural antioxidant properties to protect against free radical damage. Seaweeds are one of the richest sources of natural anti-oxidants, such as phlorotannins, sulfated polysaccarides, fucosterol and fucoxanthins.¹ Phlorotannins are different from tannins in terrestrial plants, but the physiologic properties are similar. They have anti-oxidant properties, scavenge free radicals, have chelating activity and protect against oxidative stress in cells.
Another protective ingredient for your skin? Zinc Oxide. Zinc Oxide acts a natural physical sunscreen that blocks both UVA and UVB rays.
When it comes to your skin, true protection goes beyond a chemical sunscreen. Utilizing an environmental protector as your last step before stepping out will allow your skin to get the long-lasting protection it needs while maintaining a healthy and beautiful glow.
