What is vitamin C?
Ascorbic acid or vitamin C is a powerful antioxidant that fights free radicals. It reduces the damage caused by UV radiation and polluted environments to the skin. There are different forms of ascorbic acid used in cosmetics, but what differs is their stability (their potential for rapid oxidation and thus reduced effectiveness) and the likelihood of causing skin irritation.

What are the benefits of vitamin C for the skin?
Vitamin C has been used for many years as an active ingredient in cosmetics, but it has become extremely necessary thanks to its effectiveness in fighting free radicals, reducing hyperpigmentation, and stimulating new collagen in the skin.
So, here are its main benefits:
- Anti-aging effect – It is clinically proven that vitamin C stimulates collagen production and makes the skin more elastic and firm, smoothing fine lines and wrinkles. By including a product with vitamin C in your daily routine, you provide your skin with a fresher and more youthful appearance.

- Depigmenting action – It suppresses melanin production and thus lightens dark spots, evens out and brightens the skin.

- Antioxidant protection – as one of the most powerful antioxidants, vitamin C protects the skin from free radicals that destroy collagen and elastin.
- Reduces damage caused by sun radiation and protects the skin from inflammation and irritation.
- Improves the effectiveness of sun protection, acting as a shield against UV damage. But very importantly – vitamin C itself does not have sun protection properties, it helps to deal with free radicals formed in the skin under the influence of sunlight. Therefore, some dermatologists often recommend the simultaneous use of vitamin C with sunscreen.
How is it used?
Serum, cream, or fluid with vitamin C is suitable for all skin types. The most visible and rapid results are achieved in people who are often exposed to the sun or those with uneven skin tone, fine lines, and wrinkles. The product with vitamin C can be applied morning and evening.
Morning use should be combined with appropriate sun protection so the skin is protected from UV rays and hyperpigmentation.
Evening use also has its benefits, mainly in the anti-aging direction – stimulating collagen production, evening out the skin tone, and brightening the skin. The best approach is to choose the regimen that suits your needs, being patient and consistent to achieve results.
What are the most stable forms of vitamin C?
Although vitamin C naturally exists in fruits and vegetables, it can be chemically synthesized, and this is the form used in the cosmetic industry. The purest and most active form of vitamin C is L-ascorbic acid, but there are other derivatives used in creams and serums.
As mentioned above, some forms of vitamin C oxidize very quickly, and their effectiveness sharply decreases within the first weeks after opening the package or while on the store shelf. Such is L-ascorbic acid itself, which must be used immediately while it is bioactive. You can easily recognize oxidized vitamin C by the yellow color it acquires.
Here are the most stable forms of vitamin C – ETHYL ASCORBIC ACID, TETRAHEXYLDECYL ASCORBATE, MAGNESIUM ASCORBYL PHOSPHATE.
Why did we choose 3-O-ethyl ascorbic acid for Pure Skin brightening serum with Vitamin C 15%?

The first and most important quality of 3-O-ethyl ascorbic acid is that it penetrates the skin much faster than L-ascorbic acid. Its effect and benefits are the same as pure vitamin C.
The second advantage is that it does not irritate and can be used even on more sensitive skin. Its high tolerance guarantees no redness or irritation during use.
And last but not least, it is one of the most stable forms of vitamin C, which does not lose its effectiveness while on the shelf. To ensure a long shelf life, the brightening serum from the Pure Skin series is in an airless pump packaging that prevents air from entering and further oxidizing the active ingredients.
