Q | What is vitamin C ?
A | Vitamin C, also known as (L)-ascorbic acid, is a water-soluble vitamin naturally occurring in fresh fruits and vegetables like orange, kiwi, red pepper and broccoli.
It has different names such as (L)-threoascorbic acid, antiscorbutic factor but in reality this refers to the same molecule.
Its name comes from the latin “scorbutus” as it protects from scurvy.
In the old days, pirates and long overseas sailors frequently suffered from scurvy because they could not eat fresh fruit and vegetables.
Vitamin C is indeed an essential nutrient which cannot be synthesized by humans and is mainly supplied by food.
Often associated with vitality and tonus, Vitamin C has important biological functions in the body such as the biosynthesis of collagen, required for tissue repair, or the activation of immune system. It is also a powerful anti-oxidant.
Q | Is vitamin C good for my skin?
A | From a chemistry point of view, Vitamin C is an anti-oxidant but what does it mean?
It actually refers to its capacity to neutralize harmful oxidants present in our environment.
The most abundant oxidant in the air is oxygen (20 %) responsible for iron rust or rancid butter. Ozone and free radicals are other powerful oxidants formed by air pollution (cars, fuel...).
It is now established that oxidation is a major cause of skin aging.
Not only does it alter the cell elasticity but it also affects the cellular division by damaging the DNA and the capacity of the skin to regenerate. Because it can block those mechanisms, Vitamin C has a beneficial effect on the skin.
The molecule itself is water-soluble and cannot penetrate the lipophilic layers found deeper in the skin. Therefore, this action in only superficial (epiderm) if it is used without carrier (liposome, microcapsule) for a topical application.
Added to a cream, the Vitamin C stays on the skin’s surface and offers a barrier against cell-damaging oxidative particles. It also regenerates the skin elasticity by stimulating the biosynthesis of collagen as well as new skin cells, restoring the skin’s natural glow.
Ideally, the cream should be used daily to maintain an efficient protection and stimulate the cells growth otherwise the benefits will be lost.
In addition, Vitamin C does not tackle severe aging signs such as deep wrinkles for which fillers are more suitable.
So start using it from a young age, it should be used as a preventative measure rather than a solution for already present wrinkles.
