Vitamin C as an antioxidant
Free radicals are highly reactive molecules with unpaired electrons. They can damage various vital molecules in the body such as proteins, lipids, and nucleic acids such as DNA and RNA.
They can occur through the skin’s exposure to toxins and pollutants but occur mostly through exposure to UV radiation. Side note: anti-pollution skin care is a fast-growing sector of the cosmetics’ industry. See our post on how to make anti-pollution skincare.
They are generated also through our normal internal metabolism. The internal production of free radicals increases with age, while the defence mechanisms that counter them decrease. This imbalance leads to the progressive damage of cellular structures, and results in accelerated ageing.
Antioxidants are substances that can provide protection against oxidative stresses by scavenging these free radicals.
Vitamin C works in two different ways to counter free radicals:
Firstly, vitamin C itself is an effective free radical scavenger as it provides electrons to neutralise free radicals; and secondly, it regenerates alpha-tocopherol (vitamin E) levels which helps counteract the effects of free-radical skin damage.
