Vitamine C coup d'éclat.

Vitamin C, the active ingredient for radiance.

Vitamin C, also known as ascorbic acid, is essential for the proper functioning of the body: it aids in iron absorption, stimulates the immune system to defend against viral and bacterial infections, repairs tissues, and protects the lining of blood vessels. When applied topically, this molecule with its powerful antioxidant properties neutralizes free radicals and fights against premature aging of the epidermis. Several studies have also demonstrated its brightening power.

Why do we sometimes have a dull complexion?

When toxins accumulate on the skin's surface and cellular renewal slows down, the skin becomes dull and lacks radiance. Dull skin is characterized by a lack of freshness. Signs of fatigue, pigmentation spots, dark circles, and/or puffiness also appear. It is not uncommon to observe the first signs of premature skin sagging. Dull complexion is the result of environmental factors that affect the body and poor daily habits: lack of sleep, smoking, pollution, and stress are among the main causes of this skin condition. It can also be explained by an unbalanced diet or a hormonal imbalance that contributes to the deterioration of the skin's basic functions.

Vitamin C to diminish pigmented spots.

Thehyperpigmentation is a common dermatological disorder characterized by uneven pigmentation of the skin that varies in size and color. This skin condition is typically located on the face, back, and hands. It affects approximately 90% of white-skinned individuals over the age of 70. In medical terminology, these brown spots are referred to as "melanoses".

Hyperpigmentation is typically caused by an increase in melanin production, the natural pigment that colors the skin: this process is called melanogenesis. Many factors can trigger this overproduction of melanin, but the main ones are sun exposure, aging, and hormonal fluctuations.

In dermatology, several studies have demonstrated the depigmenting power of Vitamin C. Its mechanism of action is based on theinhibition of tyrosinase, an enzyme responsible for the conversion of the amino acid tyrosine into melanin, thereby reducing pigmentation. Thus, a study showed that a 20% Vitamin C serum is capable of reducing signs of photoaging, including dark spots caused by UV rays.

Vitamin C to brighten your complexion.

Individuals who do not have pigmented spots but exhibit a dull complexion and tired appearance can also turn to a cosmetic treatment enriched with vitamin C. Indeed, its brightening power restores radiance and luminosity to the skin, while protecting it from the harmful effects of free radicals. For a truly effective brightening effect on pigmented spots and/or a dull complexion, opt for a treatment containing at least 5% vitamin C.

Typology's Vitamin C Skincare Treatments.

The skincare solutions we offer are enriched with vitamin C at various concentrations to cater to each skin issue.

  • The wrinkle and firmness loss serum is composed of 99% natural ingredients. This treatment contains plant-based collagen (1%) as well as vitamin C (10%). The hydrolyzed plant-based 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.

  • For all skin types, the brightening serum is a solution to illuminate your complexion. Apply 3 to 4 drops morning and evening on clean, dry face. A treatment of about 4 weeks is recommended to achieve the desired result.

  • If you wish to resort to a less concentrated formula, the antioxidant face cream is ideal. Apply a dab of this cream morning and evening on the face previously cleaned and dried, after your usual serum. Gently massage in circular motions to perfect the penetration.

  • Enriched with active ingredients to regulate the skin's pH, brighten the complexion, and reduce the appearance of pigmentation spots, the radiance toner 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.

  • To even out the complexion without clogging the pores, the tinted serum is a lightweight formula enriched with vitamin C and aloe vera to deeply hydrate the skin. It comes in six shades to cater to different skin tones.

There are no contraindications to using a vitamin C skincare product in the morning. This substance is photosensitive (it oxidizes in light) but not photosensitizing (it does not increase skin sensitivity when exposed to the sun). On the contrary, it is relevant to apply a vitamin C skincare product in the morning as this active ingredient will neutralize the production of free radicals generated by several external factors such as pollution, the sun, cigarette smoke...
