Why use a vitamin C serum?

You probably often hear about vitamin C.

But what is it and what is it for?

What is vitamin C?

Vitamin C , also known as ascorbic acid, is an essential vitamin for humans and animals. It has a natural origin and can be synthesized via biotechnology technologies.

In nature, vitamin C is found in many plant foods, especially citrus fruits such as oranges, lemons and grapefruit, as well as berries, kiwis, peppers, broccoli, spinach and other fruits and vegetables. It can also be present in certain organs of certain animals, such as the liver.

Vitamin C plays an important role in many biochemical reactions in the body. For example, it is necessary for the synthesis of collagen, a structural protein important for skin, bones, teeth and blood vessels. It also acts as an antioxidant, protecting the body's cells from damage caused by free radicals, unstable molecules produced during the body's normal metabolism and in response to environmental factors such as pollution and UV rays.

What are the benefits of vitamin C?

  • It stimulates cell renewal and reduces the signs of aging

Vitamin C plays a crucial role in cell renewal through several mechanisms:

  1. Collagen synthesis: Vitamin C is necessary for the synthesis of collagen, an important structural protein found in skin, bones, tendons and other connective tissues. Collagen is essential for maintaining skin structure and elasticity. By providing a substrate necessary for the formation of collagen, vitamin C promotes tissue regeneration and helps maintain youthfulness and firmness of the skin.

  2. Antioxidant: Vitamin C acts as a powerful antioxidant, protecting cells against damage caused by free radicals. Free radicals are unstable molecules that can damage cells and accelerate the aging process. By neutralizing free radicals, vitamin C helps prevent oxidative damage and maintain the integrity of cells, thus promoting their renewal.

  3. Protection against UV rays: Ultraviolet (UV) rays from the sun can damage the DNA of skin cells and lead to premature aging of the skin. Vitamin C acts as a protective agent against UV rays by reducing the damage caused by free radicals generated by UV exposure. By protecting skin cells against UV damage, vitamin C helps maintain their integrity and promotes their renewal.

  4. Tissue repair: In addition to promoting collagen synthesis, vitamin C is also involved in the repair of damaged tissues. It plays a role in producing new cells to replace those that have been damaged or aged. By accelerating the tissue repair process, vitamin C contributes to cell renewal and skin regeneration.

In summary, vitamin C stimulates cell turnover by promoting collagen synthesis, acting as an antioxidant to protect cells against oxidative damage, providing protection against UV rays, and facilitating the repair of damaged tissues. These combined mechanisms of action help maintain the health and youthfulness of the skin by promoting its continuous renewal.

  • Protection against environmental aggressors

Our skin is constantly exposed to a variety of environmental stressors such as pollution, UV rays and oxidative stress. These factors can lead to dull complexion , premature wrinkles and cellular damage. Thanks to its antioxidant properties, a vitamin C serum acts as a protective shield, protecting the skin against these attacks and promoting its ability to regenerate.

  • Improved skin texture

Dull skin can particularly benefit from using a vitamin C serum. With its brightening properties, vitamin C helps remove dead skin cells and reveal a brighter, more even complexion. Combined with ingredients such as hyaluronic acid and bark extract, which provide additional hydration and protection, it can transform the texture of your skin to make it softer, smoother and more youthful.

Vitamin C also acts as a hydrating active ingredient, helping the skin retain moisture and maintain its natural hydration. Well-hydrated skin feels softer, more supple and smoother to the touch, improving its texture and making it look healthier and more radiant.

Vitamin C also has anti-inflammatory properties that can help soothe skin irritation and redness. By reducing inflammation, vitamin C helps improve skin texture and give it a more even, calmer appearance.

What skin type does vitamin C correspond to?

Vitamin C is suitable for all skin types . Whether you have oily, dry, combination, or sensitive skin, a vitamin C serum may benefit you. Unlike some skincare products that may be too rich or irritating for certain skin types, vitamin C is generally well tolerated and can even help soothe sensitive skin . In addition, it acts as a hydrating active ingredient , helping to maintain skin hydration and prevent dryness.

Why use a vitamin C serum before your cream?

Using a vitamin C serum before your cream offers several benefits for the health and appearance of the skin. Here are some reasons why it is recommended to apply a vitamin C serum before your cream:

  1. Better Absorption: Serums are generally formulated with active ingredients at higher concentrations and in lightweight formulations that allow for better penetration into the skin. By applying a vitamin C serum first, you allow its active ingredients to be absorbed more effectively by the skin, maximizing their benefits.

  2. High concentration of vitamin C: Vitamin C serums are often formulated with high concentrations of this key ingredient. By applying a vitamin C serum before your cream, you ensure you're providing your skin with a concentrated dose of this powerful antioxidant, which can help protect skin from oxidative damage, boost collagen production, and brighten the complexion.

  3. Targeted Action: Vitamin C serums are often designed to target specific skin concerns, such as signs of aging, age spots , or free radical damage. By applying a vitamin C serum before your cream, you allow its active ingredients to work deeply to address these specific concerns, while your cream can provide additional hydration and other skin benefits.

  4. Extra protection: By applying a vitamin C serum before your cream, you create a protective barrier on the skin that can help protect against environmental aggressors such as UV rays, pollution and oxidative stress. This can help prevent skin damage and maintain long-term skin health and youthfulness.

In summary, using a vitamin C serum before your cream offers several benefits, including better absorption of active ingredients, a high concentration of vitamin C, targeted action on specific skin problems and additional protection against environmental aggressions. By incorporating it into your skincare routine , you can maximize the benefits of vitamin C to give your skin a glowing, smooth complexion.


In conclusion, using a vitamin C serum is an effective way to improve the health and appearance of your skin for an anti-aging effect. By neutralizing free radicals , stimulating cell renewal, protecting the skin against environmental aggressors and reducing the signs of aging, vitamin C offers a multitude of benefits for all skin types. Whether you're battling fine lines and wrinkles , age spots, or just dull skin , adding a vitamin C serum to your skincare routine can help your skin regain its natural glow and youthfulness.
