How is it  used in our products ?
We use vitamin C in our anti-aging skincare products for its antioxidant and anti-inflammatory properties and its benefits on the radiance and uniformity of the complexion.
As vitamin C is sensitive to light, it is formulated under conditions that preserve its stability. Vitamin C products are packaged in airtight bottles or opaque protective aluminium tubes. We also use microencapsulated forms of vitamin C.
Vitamin CG is used in our blemish-reducing product ranges, given its potential to limit the pigmentation caused by repeated exposure to the sun. In some Asian countries such as Japan, Korea and Taiwan, vitamin CG is an active ingredient considered by law as a Quasi-Drug, i.e. between a cosmetic and a drug. Its use in cosmetic products, to combat skin blotches, is regulated. For example, in Taiwan, the level of vitamin CG in a blemish removal product must be 2%. We comply with these regulations for all our products containing vitamin CG.
Vitamin C is present in some of our peeling products at a level higher than 10%. For this type of product, it is recommended to follow the precautions for use indicated on the packaging, such as avoiding the eye area, not exposing oneself to the sun and using a sun protection product. Vitamin C is suitable for use with sensitive skin. Like all our products, those containing vitamin C are subject to strict evaluation of their quality and safety.
What are the  benefits ?
Vitamin CG is a precursor of vitamin C, which means that in the presence of certain substances on the surface of the skin, it will release vitamin C. Vitamin CG is particularly used for its properties to unify the complexion. This benefit is enhanced by the proven anti-inflammatory activity of vitamin C.
In cosmetics, thanks to its antioxidant properties, vitamin C helps reduce the action of free radicals created by the sun's rays, and thus prevent premature skin aging from sun exposure. It is known to promote collagen synthesis and the production of dermal cells such as fibroblasts, that decrease in the skin with age. Its antioxidant action is even stronger in the presence of vitamin E, as it is regenerated by vitamin C.
- Scientific data shows that vitamin CG applied on the surface of the skin is transformed into vitamin C through the action of substances present on the skin, such as phosphatases or glycosidases.
- One study1 reports the well-known properties of vitamin C such as its antioxidant power and its effect on collagen synthesis2. It shows the positive effects of a vitamin C skincare cream on the signs of aging caused by exposure to the sun.
- One study3 shows that vitamin C, in addition to its antioxidant activity, also has anti-inflammatory properties.
- One study4 has shown that vitamin E regeneration thanks to vitamin C, thus reinforces their antioxidant powers.
- Repeated exposure to the sun leads to skin pigmentation due to increased melanin production. Vitamin C, already known for its properties on complexion uniformity, was studied5 to evaluate its potential to limit the pigmentation caused by daily exposure to ultra-violet radiation.
- To maximize the benefits of vitamin C in cosmetic products, a study6 was conducted on ways to improve its stability.

What is vitamin  C ?
Vitamin C is a water-soluble vitamin, i.e. it dissolves well in water. It occurs naturally in the human body and is involved in many bodily processes, such as the synthesis of collagen and red blood cells. The main source of vitamin C to the body is external, through food. It is also found in colourful fruits and vegetables such as oranges, lemons, grapefruit, kiwi, broccoli and red pepper. It is sensitive to heat and light. There is a more stable form used in cosmetics, vitamin C glucoside - vitamin CG.
In our cosmetic products, they appear in the list of ingredients on the packaging under the names ASCORBIC ACID and ASCORBYL GLUCOSIDE.
Where does it  come from ?
Vitamin C can be of fossil (petrochemical) or natural origin. We use several sources of vitamin C, most of which are renewable. A programme with one of our partners enables us to obtain natural vitamin C using a manufacturing process that complies with the principles of green chemistry*. The vitamin C glucoside we use is exclusively of natural origin.
