Renowned for its benefits on the immune system and the fight against oxidative stress, vitamin C also plays a role in skin quality . It participates in the formation of collagen, reduces wrinkles and protects against free radicals. The before/after results of vitamin C on the face are numerous: luminous complexion, elastic and smooth skin, accelerated cell renewal and even reduction of dark spots. Nooance-Paris gives you its best advice for incorporating this antioxidant active ingredient into your beauty routine and giving your skin a boost of radiance in just a few weeks.
An ingredient that makes the difference in facial care
It is originally a water-soluble vitamin essential to the metabolism of the human body, to reduce fatigue, support the immune system and protect skin cells against external aggressions.
Today, vitamin C, or ascorbic acid, is a key active ingredient in cosmetic treatments in the form of serums and creams. It offers powerful antioxidant action against free radicals while also addressing various skin problems.
This multifunctional ingredient is therefore effective at both:
- in prevention: anti-aging, collagen stimulation, protects the skin from external aggressions (pollution, UV rays) responsible for premature aging
- in correction: unified complexion, reduction of pigment spots and acne marks, revived radiance.

Practical guide: safely incorporating vitamin C into your skincare routine
Is it good to apply vitamin C to the face?
Vitamin C is generally suitable for all skin types and offers many benefits, including brighter, more even-toned skin. We recommend always performing a patch test on a small area of your face before daily application.
How often should I apply vitamin C?
For effective application, use your vitamin C-based care twice a day:
- In the morning, after cleansing your skin with a mild soap, start with your vitamin C serum, then apply your moisturizer and finally sunscreen.
- In the evening, on clean, makeup-free skin, as a night cream or before a hyaluronic acid cream for better hydration.
Ascorbic acid: precautions for use and contraindications
- Vitamin C concentration
Always check the composition of skincare formulas: vitamin C is listed as “L-ascorbic acid” in the ingredient list. Ideally, the serum or cream should contain at least 10% ascorbic acid for topical application.
- Sensitive skin
Fragile skin (dry skin, dehydrated skin or combination skin prone to redness) is more sensitive to irritation: carry out a skin test and gradually integrate vitamin C into your skincare routine.
- Association with other assets
Vitamin C can be unstable or irritating on all skin types when combined with exfoliating acids (AHA, BHA). Avoid using them on top of each other whenever possible, or alternate between vitamin C and fruit acid facial treatments.
Our beauty tips to boost the radiance effect of vitamin C
For an even more effective targeted routine, combine vitamin C with other powerful cosmetic active ingredients, depending on your needs and skin type:

Hyaluronic acid helps keep skin supple and plump, while enhancing the radiance provided by vitamin C. Brighten the complexion with our Intense Radiance Day Cream formulated with ascorbic acid and two forms of hyaluronic acid, for deep skin hydration.
Hyperpigmentation
In addition to vitamin C, tranexamic acid helps reduce the appearance of dark spots and even out skin tone faster. Improve your skin's texture and clarity with Nooānce Paris Unifying Radiance Cream , which combines the brightening power of vitamin C with the depigmenting action of tranexamic acid.
Anti-aging
To effectively target the signs of aging, alternate between retinol and vitamin C treatments.

You can also apply a concentrated cream like the 1% Retinol Anti-Aging Night Treatment : its unique formula with retinol and vitamin C derivatives corrects the signs of skin aging.
