An essential vitamin for the proper functioning of the body, vitamin C also abounds with benefits for the skin. When applied topically, this active ingredient neutralizes free radicals induced by several factors such as stress, smoking, sun exposure, lack of sleep, and more. 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.

How does skin aging manifest itself?
Skin aging is an unavoidable phenomenon in living beings. It is due, among other things, 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...) and the melting of fatty and muscular tissue that no longer plays its supporting role.
Furthermore, this natural process can be accelerated by lifestyle factors (poor diet, smoking, excessive alcohol consumption, sun exposure, stress, lack of sleep...).
Skin aging is then characterized by the appearance of wrinkles, pigment spots, visible dilated vessels and a thinning or thickening of the epidermis.
Vitamin C to combat skin aging.
Vitamin C, or L-ascorbic acid, is particularly relevant for topical application to combat the appearance of aging signs. Its effectiveness is based on three essential actions:
Neutralizing free radicals:
Free radicals, generated by a variety of factors (pollution, cigarette smoke, stress, etc.), attack skin cells and accelerate their aging. Vitamin C neutralizes the action of these free radicals by donating an electron to make these molecules more stable and less reactive. In this way, it delays skin aging and protects the skin from external aggressions.
Stimulating collagen production:
Collagen is a fibrous protein found in the dermis that provides flexibility and firmness to the skin. However, over the years, its production by the body tends to decrease, leading to skin sagging and the appearance of wrinkles. To counteract this, vitamin C is a true ally as it boosts the synthesis of collagen in the skin and thus slows down the appearance of signs related to skin aging.
Preventing the appearance of spots:
Several studies have demonstrated the lightening power of Vitamin C. This molecule inhibits the amount of melanin produced by the skin's pigment cells. It interacts with tyrosinase, an enzyme responsible for converting the amino acid tyrosine into melanin, thereby reducing pigmentation.
Our Vitamin C skincare treatments.
In order to minimize the signs of aging, Typology offers skincare treatments with varying concentrations of Vitamin C, suitable for all skin types:
The Wrinkle and Firmness Serum is composed of 99% natural ingredients. This treatment contains vegetable collagen (1%) as well as vitamin C (10%). The hydrolyzed vegetable collagen, known in the I.N.C.I. as " Cocoyl Hydrolyzed Collagen/Collagen Amino Acids" is a biotechnological active ingredient that mimics type I human collagen. It works in synergy with vitamin C to stimulate fibroblasts, which produce collagen fibers and thus reduce the depth of wrinkles.
The radiance facial serum is highly concentrated in Vitamin C (11%) and provides a real boost to dull and tired complexions. This treatment also contains 3% of Albizia Julibrissin extract. This Asian-origin plant restores vitality to the skin. Together, these ingredients help slow down photo-aging.
The antioxidant face cream is more suitable for sensitive skin, its concentration of vitamin C being lower than that found in the serum. This cream works on the skin cells in depth to prevent premature aging. It also tones the complexion and hydrates the skin.
Enriched with active ingredients to balance the skin's pH, brighten the complexion, and reduce the appearance of pigmentation spots, the Vitamin C Radiance Tonic also contains lemon verbena water for a light fruity scent. After the makeup removal steps, this toning lotion is applied with a cotton pad to the entire face, avoiding the eye contour, and does not need to be rinsed off.
