Know that vitamin C is also necessary for the skin and it is even a real one. vitality and beauty booster.
What is Vitamin C?
Vitamin C, also called ascorbic acid, is an essential vitamin for the human body. Since the body cannot synthesize it, it must be provided through food (mainly in fruits and more particularly in citrus fruits).
Vitamin C, essential nutrient for tissue repair as well as many enzymatic processes, strengthens the immune system and helps to keep us healthy.
Although food intakes of vitamin C are in principle sufficient as part of a balanced diet, the skin benefits more from its benefits when it is applied topically, that is to say directly on the skin.
The boosting benefits of vitamin C
Powerful antioxidant and anti-aging active
Vitamin C helps the skin to regulate the free radicals produced by the cells and thus helps to prevent oxidative stress, a process involved in the phenomena of aging and cell degeneration.
Learn more about the benefits of antioxidants with the article "Antioxidants, essential anti-aging active ingredients".
Powerful lightening and Radiance and anti-dark spot active
Vitamin C slows melanin production by regulating the activity of tyrosinase, an enzyme present in the skin, which activates the transformation of tyrosine (amino acid) into melanin, pigment responsible for uneven skin tone and the presence of brown spots.
Applying Vitamin C to the skin helps restore brighter skin, and to reduce and prevent the development of pigment spots such as sunspots (melasma or chloasma), acne marks and the age spots.
Collagen production booster and anti-wrinkle active
Vitamin C stimulates the production of collagen, making the firmer skin and more luscious.
The collagen is a protein naturally and abundantly present in our body and found in large quantities in the skin. THE collagen is a structural protein or support that gives the skin its good support and sa fermeté.
As we age, the production of collagen slows down, which can lead to a loss of skin tone, making it more susceptible to the appearance of fine lines, wrinkles, and sagging tissue.
When applied topically, the vitamin C supports collagen production, helping to keep skin plumper, firmer and smoother.
What form of Vitamin C to use?
Pure vitamin C is ascorbic acid, but the latter is unstable and deteriorates by oxidation in light and air. Derivatives have been developed and the latest generation is promising both in terms of stability and ability to penetrate the skin: theethylascorbic acid or EAC.
When and how to apply Vitamin C?
A morning and/or evening application?
Vitamin C is not photosensitizing and can therefore be applied during your evening or morning routine.
It is advisable to use your Vitamin C treatment:
- into your morning routine to help your skin fight the day's aggressors such as the effects of UV rays and pollution. It should be noted that, of course, a vitamin C intake does not replace sunscreen, which remains essential.
- within your evening routine to take advantage of this period of reconstruction that is the night for the body and the skin.
Vitamin C Serum or Vitamin C Cream?
A Vitamin C serum is much more concentrated in vitamin C than a cream and for skin that is usually acid-sensitive it may be advisable to start with a Vitamin C cream or a drop of Vitamin C serum in your application of moisturizer. You can then increase the dosage and switch to serum.
What other active ingredients can be combined with Vitamin C?
We do not recommend a mono-ingredient serum concentrated in vitamin C and prefer serums or creams offering several active ingredients:
- the concentration of vitamin C in a treatment does not exceed 15 to 20% of the formula. It is advisable to avoid a treatment composed of 60 or 80% water and rather to integrate within the same treatment and the same gesture other quality active ingredients beneficial to the skin and responding to your concerns. .
- vitamin C is an anti-aging, anti-wrinkle and anti-dark spot active, but these aging processes are multifactorial and their prevention does not only require a "miracle active", but a set of beneficial factors and actives.
