What is Vitamin C?

Vitamin C is a naturally occurring antioxidant in nature and is also an essential nutrient required by humans as well as certain other species of animal.

It is also popularly known as ascorbic acid and is responsible for activating 8 enzymes in the body, including several collagens.

These collagen reactions when dysfunctional might cause severe symptoms of scurvy.

Though most animals have the capacity to synthesize vitamin C internally from glucose, humans are not able to do so.

Humans with some other invertebrates lack the L-glucono-gamma lactone oxidase enzyme, which assists the synthesis of Vitamin C.

They must, therefore, rely on external sources of vitamin C which includes citrus fruits and green vegetables among others.

Vitamin C is essential for the development and proper functioning of different parts of the body and also helps in strengthening the immunity system.

The collagen synthesis reactions are specifically effective in the healing of wounds and prevention of bleeding from capillaries.

It also functions as a natural anti-oxidant against oxidative stress.

Vitamin C exhibits anti-oxidant and anti-inflammatory properties which help in preventing and correcting acne breakouts.

It also helps in undoing the pigmentation caused by acne inflammations.

Vitamin C is, however, an unstable compound and is often combined with other agents to perform its function.

Vitamin C is a naturally occurring and one of the most plentiful anti-oxidant and forms a complex part of enzymatic and non-enzymatic anti-oxidizing nutrients. It reduces oxidative stress by neutralizing the free radicals.

This anti-oxidant nature helps vitamin C in fighting the acne-causing bacteria.

It also provides protection against the harmful UV rays on the Sun but tends to provide better protection when combined with vitamin E.

Apart from this, it also has anti-inflammatory properties and helps in reducing the inflammation caused due to acne breakouts.

It further helps in reducing the post inflammation pigmentation by interrupting the steps of melanogenesis, decreasing the melanin formation and thereby becomes an important de-pigmentation agent.
