What are anti-oxidants and how do they work? To understand this we’d need to know what is oxidation.
As we all know, living in the city, our skin is exposed to a variety of external aggressors every day. Exposure to UV light, environmental pollutants, and exposure to microbes are a just few examples.
How does our skin react to them? It gives an inflammatory response to these aggressors.
Although our skin has its own anti-oxidants to neutralise some of the elements these aggressors generate, but when there are too many of them, there are not enough antioxidants in our body, then the neutralisation mechanism will be compromised, and damage organic molecules in our skin like lipids and proteins, resulting in an acceleration of ageing.
We can help supplement the body’s own antioxidants supply by external application. For example, Vitamin C and E are proven to be very effective anti-oxidants WHEN APPLIED TO SKIN. What we’d need to consider though, is that the Vitamin C is in a stabilised form, for example on the product label, you can look for Ascorbyl Phosphate. A vitamin C that’s stable is important as it usually takes a while for us to finish a jar of skincare product. If a vitamin is unstable and can easily be degraded by time or change of temperature, we will be putting oxidised vitamin C onto our skin, which completely defeats the purpose. Research has also shown that natural vitamin E is more potent and has a higher retention rate, meaning they’re being absorbed better by our skin than the synthetic ones.
