Vitamin C is one of the best-known antioxidants in modern skin care. The active ingredient is used in particular when the care routine is aimed at a more even, radiant and smooth-looking skin as well as visible signs of skin aging. But not all vitamin C is the same.

Concentration, vitamin C form and, above all, the formulation can determine how a serum is constructed and how it should be used.

What does vitamin C do on the skin?

Vitamin C is used in skin care particularly because of its antioxidant properties. It is one of the more useful skincare ingredients, especially in a properly formulated serum. Its main benefits are:

• Brightens the skin: Can reduce dullness and give the skin a more even, radiant appearance.
• Helps with dark spots: Regular use can gradually fade hyperpigmentation and post-acne marks by reducing melanin production.
• Supports collagen: Vitamin C is needed for collagen synthesis, so it can help improve the appearance of fine lines and maintain skin firmness over time.
• Antioxidant protection: It helps neutralize free radicals generated by UV exposure and pollution. It doesn't replace sunscreen, though.
• Can reduce signs of inflammation: It may help calm some redness and irritation, depending on the formulation and your skin.

With the DS V-LINE Vitamin C Serum you have a clear difference to many classic vitamin C serums: 10% ascorbic acid (L-ascorbic acid), anhydrous formulation and only two INCI main ingredients: propanediol and ascorbic acid. The official product information lists four essential areas:

•⁠ ⁠Protect the skin from free radicals
•⁠ ⁠Support collagen synthesis
•⁠ ⁠Improving the appearance and clarity of the skin
•⁠ ⁠Reducing the appearance of wrinkles, pigment spots and discoloration

What does L-ascorbic acid mean?

Ascorbic acid, also L-ascorbic acid, is a form of vitamin C that is used in cosmetic formulations. When it comes to vitamin C products, you should therefore not only pay attention to the fact that it says “Vitamin C” on the packaging.

Why is vitamin C an antioxidant?

Our skin is exposed to various external influences every day. Antioxidants therefore play an important role in modern skin care routines.

The product information of our DS V-LINE Vitamin C Serum specifically describes vitamin C as an antioxidant and cites protection against free radicals as one of the benefits of the formulation. 

That's why vitamin C is particularly interesting as part of a well-thought-out daily skincare routine.

Vitamin C in the morning or evening?

According to our product information, it can be applied to the cleansed face in the morning and evening. 

After application, the serum should first be absorbed. Moisturizing can then follow.

How many drops of Vitamin C Serum should you use?

Especially with concentrated serums, more product does not automatically mean more effect. The no. According to the product information, 47 has a dense and very rich consistency due to its water-free formulation.

Therefore, a maximum of: 2-3 drops per application.

The right vitamin C routine in the morning is important. A simple routine can be set up like this:

1.⁠ ⁠Cleaning
Gently cleanse the skin.

2.⁠ ⁠Vitamin C serum
2-3 drops No. Apply 47 to cleansed face.

3.⁠ ⁠Let it absorb

4.⁠ ⁠Moisturizing
Use care tailored to your individual skin type.

5.⁠ ⁠Sun protection
Finish your morning skincare routine with suitable sun protection.

Why Vitamin C is so important for skincare?

Vitamin C is important in skincare because it provides multiple benefits at once: it helps brighten the complexion, supports collagen production and protects the skin from oxidative stress.

But one thing is important to know: Vitamin C works especially well alongside sunscreen. It provides antioxidant support, but it does not replace SPF. Using both can provide more comprehensive protection against environmental damage.

How Does Vitamin C Work on the Skin?

Vitamin C works on the skin in several ways, which is why it has become such a popular ingredient in modern skincare. As a powerful antioxidant, vitamin C helps neutralize free radicals that are generated by environmental stressors such as UV exposure and pollution. This antioxidant activity can help support the skin against oxidative stress and visible signs of premature skin aging.

Vitamin C also plays an important role in collagen synthesis. Collagen is a structural protein that helps maintain the skin's firmness and elasticity. By supporting collagen production, topical vitamin C can contribute to a smoother-looking complexion and help reduce the appearance of fine lines and wrinkles over time.

Another important benefit of vitamin C is its effect on pigmentation. L-ascorbic acid can influence melanin production, which makes topical vitamin C particularly interesting for skin with an uneven complexion, dark spots and post-acne marks. With consistent use, vitamin C can help improve the appearance of uneven skin tone and promote a brighter, more radiant complexion.

The effectiveness of a vitamin C serum, however, does not depend only on the amount of vitamin C it contains. The form of vitamin C, the concentration, the pH and the overall formulation all play an important role in how the ingredient performs on the skin. Research has shown that formulation characteristics are particularly important for the stability and penetration of topical L-ascorbic acid.

What Percentage of Vitamin C Is Best for Your Skin?

When choosing a vitamin C serum, concentration is one of the most commonly considered factors. However, a higher percentage does not automatically mean a better product or better results.

L-ascorbic acid is one of the most extensively studied forms of topical vitamin C. Research on topical L-ascorbic acid has investigated concentrations ranging from lower percentages to concentrations around 20%, with formulation and skin tolerance being important considerations.

For many skincare routines, a moderate concentration can provide a good balance between efficacy and skin tolerance. The ideal concentration ultimately depends on the formulation, the type of vitamin C used and the individual's skin.

Is 10% Vitamin C Enough?

A 10% vitamin C serum can be an effective option for incorporating L-ascorbic acid into a daily skincare routine. Rather than focusing solely on the highest possible concentration, it is important to consider the complete formulation and how consistently the product can be used.

The DS V-LINE Vitamin C Serum contains 10% L-ascorbic acid in an anhydrous, water-free formulation. Its minimalist formulation contains propanediol and ascorbic acid as the main INCI ingredients.

For anyone new to vitamin C or looking for a concentrated serum that can be incorporated into a consistent skincare routine, a 10% formulation can therefore be an interesting option.
