An essential supplement for the proper functioning of the body, vitamin C is also full of benefits for the skin. When applied to the skin, this active ingredient neutralizes the free radicals induced by several factors such as stress, smoking, exposure to sun, lack of sleep... Thus, it limits oxidative stress and slows down skin aging and the appearance of wrinkles. Vitamin C also stimulates the production of collagen, an essential protein for skin firmness. This formidable active ingredient against the marks of time in focus.

How Does Our Skin Age?
Skin aging is an inevitable phenomenon in living beings. It is due to a decrease in the rate of cell renewal, a change in the composition of the dermis and the molecules that make it up (hyaluronic acid, collagen, etc.) and the melting of fatty and muscular tissue that no longer plays its supporting role.
Moreover, this natural process can be accelerated by lifestyle (poor diet, smoking, excessive alcohol consumption, sun exposure, stress, lack of sleep...).
Skin aging then results in the appearance of wrinkles, pigment spots, visible dilated vessels and thinning or thickening of the epidermis.
Vitamin C to Slow Down Skin Aging.
Vitamin C or L-ascorbic acid is particularly beneficial in topical application to fight against the appearance of signs of skin aging. Its effectiveness is based on three essential actions:
Neutralizing free radicals:
Free radicals generated by all sorts of factors (pollution, cigarette smoke, stress etc...) attack the skin cells and accelerate its aging. Vitamin C neutralizes the action of free radicals by giving up an electron to make these molecules more stable and less reactive. Thus, the skin benefits from it, delaying skin aging and protecting it from external aggressions.
Stimulate the production of collagen:
Collagen is a fibrous protein present in the dermis that ensures flexibility and firmness to the skin. Nevertheless, over the years, its production by the body tends to decrease, which leads to skin slackening and the appearance of wrinkles. To counteract this, vitamin C is a real ally because it boosts collagen synthesis in the skin and thus slows down the appearance of signs of skin aging.
Prevent the appearance of spots:
Several studies have demonstrated the lightning power of vitamin C. This molecule inhibits the amount of melanin generated by the skin's pigment cells. It interacts with tyrosinase, an enzyme responsible for the conversion of the amino acid tyrosine into melanin, and thus reduces pigmentation.
Our Skincare Products With Vitamin C.
In order to limit the signs of aging, Typology offers care products more or less concentrated in vitamin C, adapted to all skin types:
The wrinkle and firmness serum is made of 99% natural ingredients. This treatment contains plant collagen (1%) and vitamin C (10%). Hydrolyzed plant collagen, INCI designated “Cocoyl Hydrolyzed Collagen/Collagen Amino Acids”, is a biotechnological active ingredient that mimics type I human collagen. It acts in synergy with vitamin C to stimulate fibroblasts, which produce collagen fibers, and thus reduce the depth of wrinkles.
The radiance face serum is highly concentrated in vitamin C (11%) and gives a real boost to dull and tired complexions. This treatment also contains 3% Albizia Julibrissin extract. This plant of Asian origin restores vitality to the skin. Together, these ingredients help slow down photoaging.
The antioxidant face cream is more suitable for sensitive skin, as its vitamin C concentration is lower than that of the serum. This cream acts on the skin cells in depth to prevent premature aging. It also tones the complexion and moisturizes the skin.
Concentrated in active ingredients to regulate the skin's pH, brighten the complexion and reduce the appearance of dark spots, the vitamin C radiance toner also contains lemon verbena water for a light fruity scent. After the makeup removal steps, this toner is applied with a cotton pad over the entire face, avoiding the eye area, and does not need to be rinsed off.
