What is Vitamin C?
Vitamin C is also called “ascorbic acid.” It is a water-soluble vitamin, meaning it dissolves in water and is then eliminated through the kidneys.
Thus, it is not stored by the body. This is why it is important to have sufficient daily intake.
This vitamin is best known for its stimulating effect on the body. It is recommended to reduce fatigue, and to regain energy and vitality.
Its benefits extend to the immune system which it helps to activate and strengthen. By boosting natural defenses, it would help fight infections.
Vitamin C is less known for its role on the skin. Yet, its beneficial effects are numerous!

A great protector, it helps to combat free radicals and prevents their damage such as premature skin aging.
It is also essential for the synthesis of collagen and the healing process. Lastly, it enhances skin beauty by bringing a glow to the complexion and reducing dark spots.
To enjoy its benefits, prioritize foods rich in Vitamin C like camu camu, blackcurrants, citrus fruits, or rose hips.
It is also possible to take dietary supplements.
Vitamin C can also be used topically, directly on the skin. It is then applied in the form of a cream or serum.
In this way, it is not distributed throughout the body but intended solely for the skin and cutaneous tissue. Its action is therefore more targeted.
Its Benefits on the Skin
It Slows Down Skin Aging
Vitamin C exerts an antioxidant action meaning it fights free radicals, prevents their proliferation, and prevents their damage.
It is even capable of trapping them to better eliminate them. For this, it acts in synergy with Vitamin E and provitamin A (beta-carotene).
Free radicals accelerate skin aging and promote the appearance of signs of aging: wrinkles, dark spots, loss of glow and elasticity…
They are also responsible for oxidative stress that affects the cutaneous structure.
Vitamin C slows this phenomenon and preserves the youthfulness of the skin. This is why it is often added to anti-aging skin care products.
Finally, it protects against damage caused by UV rays which accelerate the aging of skin cells and tissues.
As shown by this study, it plays a major role on the skin.

It Supports Collagen Production
Vitamin C is closely linked to collagen biosynthesis. This protein, present at the dermis level, ensures the maintenance and cohesion of tissues.
It provides flexibility and elasticity to the skin. Furthermore, it is essential for hydration, tissue regeneration, and healing.

Therefore, collagen production is not possible without Vitamin C. Indeed, it is the one that induces the hydroxylation reaction that modifies certain amino acids, like proline and lysine.
This process is necessary for the fabrication of collagen fibers.
This study shows the action of Vitamin C on collagen production.
It Brings Radiance to the Complexion
Vitamin C boosts the skin’s radiance and contributes to a fresher and more luminous complexion. It is ideal in case of a dull, tired, or grayish complexion, helping to regain a healthy appearance.
Additionally, it unifies the complexion and corrects hyperpigmentation by reducing the appearance of dark spots on the hands and face. It does this by reducing the oxidation of melanin, which causes darkening.
In this study, vitamin C was used to reduce skin hyperpigmentation.
It promotes healing
By ensuring collagen production, it speeds up the healing process. Indeed, collagen is essential for the renewal and regeneration of tissues in case of wounds (injuries, burns…).
It is also useful for reducing acne scars or other skin conditions: psoriasis, eczema…
This study shows the importance of vitamin C on the healing process and collagen production.
How to use vitamin C for the skin?
As a dietary supplement
As a dietary supplement, it comes in the form of capsules, tablets, drops, powder, or gummies. It can be pure or combined with other active ingredients: hyaluronic acid, marine collagen, vitamins A and E…
It is often found in complexes for skin beauty.
For greater effectiveness, choose liposomal vitamin C. It is protected from oxidation and offers better absorption by the body. Thus, your skin will feel more of its benefits.
For external use
It’s possible to enjoy its beneficial effects by applying vitamin C-based skincare products. Day creams, serums, lotions… often contain it.
They are beneficial for providing a radiant boost to dull and tired complexions and for protecting the skin from free radicals.
Be cautious if you have sensitive skin: products concentrated in vitamin C (>15%) can cause irritations, discomfort, or tightness. Perform a patch test in the crook of your elbow to detect signs of a skin reaction.
