What is it?

TheVitamin CIt is a powerful antioxidant widely used in cosmetics for its ability to protect the skin against oxidative stress and visibly improve its radiance.

On the skin, it helps neutralize free radicals generated by sun exposure, pollution, and other environmental factors. It also participates in the synthesis of collagen, a key protein for maintaining skin firmness and elasticity.

Where does it come from and how is it obtained for cosmetics?

Vitamin C occurs naturally in fruits and vegetables such as citrus fruits, kiwis, and acerola cherries. However, these fresh extracts are not used directly in cosmetics.

To ensure stability, purity, and efficacy, the vitamin C used in the formulation is obtained through controlled processes that allow:

1. Ensure precise and consistent concentration.
2. Improve its stability against oxidation.
3. Develop more tolerable forms for sensitive skin.

In cosmetics we can find:

• Ascorbic acid: the pure form, very effective but more unstable and sensitive to light and air.
• Vitamin C derivatives: more stable versions that transform into active vitamin C once applied to the skin.

What is it for?

1. It adds brightness
   It improves dull and uneven skin, helping it to look more even.
2. Antioxidant action
   Protects against daily oxidative damage caused by UV radiation and pollution.
3. Improved firmness
   It participates in the production of collagen, helping to maintain the structure of the skin.
4. Unification of tone
   It helps reduce the appearance of blemishes and promotes a more even skin tone with consistent use.
5. Support in the face of signs of maturity
   It helps to maintain more elastic skin with a better texture over time.

Interesting facts

• It is "photosensitive" but not "photosensitizing":This is the biggest curiosity and misunderstanding. Vitamin C does not cause sunspots; rather,It oxidizes and loses effectivenessWhen exposed to light and air (which is why it usually comes in dark bottles), it degrades. Conversely, it helps protect the skin from sun damage.
• The best natural sources (beyond oranges):Although we associate vitamin C with citrus fruits, in natural cosmetics more concentrated sources are sought, such asKakadu plum(the richest known natural source), thehip(rosehip), thecamu-camuor theacerola.
• It oxidizes and changes color:When a natural vitamin C serum turns brown or dark orange, it means it has oxidized and lost its antioxidant effectiveness.
• It needs an acidic pH to function:The pure form of vitamin C (ascorbic acid) requires a low pH (between 3 and 4) to effectively penetrate the skin barrier. This is why it can be irritating to very sensitive skin.
• Combats "smoker's skin" and stress:It is the best remedy for dull and tired skin, as it stimulates collagen synthesis, improving firmness and luminosity, making it ideal for restoring natural radiance.
• You shouldn't mix it with everything:To maintain its effectiveness, avoid using it simultaneously with niacinamide, as they can neutralize each other, or with exfoliating acids (AHA/BHA) to avoid extreme irritation.
• Synergy with Vitamin E:When vitamin C is combined with vitamin E (tocopherol), its stability and antioxidant efficacy increase significantly.

Vitamin C is a functional ingredient backed by scientific evidence, which we have selected for our product line because of its ability to enhance radiance and boost daily antioxidant protection without disrupting the skin's natural balance. It fits perfectly into a mindful skincare approach, where the goal is not to "correct the signs of aging," but rather to preserve the skin's vitality, evenness, and quality over time.
