Best Best Vitamin C Serum – our TOP 3 Products

Our Top Pick: Instanatural Vitamin C Serum

Best Vitamin C Serum No 1

  • “Test winner and at the same time also our celebrated great value tip”
  • Instanatural’s Vitamin C Serum turned out to be our test winner.
  • Next to a high concentration of Ascorbic Acid (20%), this Serum contains an active ingredient complex consisting of Hyaluronic Acid, Vitamin E, Ferulic Acid, as well as other natural oils and herbal stem cells.
  • Due to its ingredients, Instanatural Vitamin C Serum is a useful supplement to the daily anti-aging care of facial skin. We recommend to apply this serum in the morning or in the evening after a thorough facial cleansing. According to skin type, a care cream (if necessary with permanent sun protection factor) can be applied after the serum has soaked in.
  • The Instanatural Vitamin C Serum comes in a yellow, slightly murky color and is delivered in a light-protected blue glass bottle. The concentrated Hyaluronic Acid provides the skin with much needed moisture, while anti-aging ingredients fight against wrinkles and improve the skin’s structure and texture.
  • The anti-oxidative effect of the Vitamin C is improved by the addition of Vitamin E. These vitamins harmonize well with each other and help themselves, so to speak, mutually.
  • The active ingredient complex is further enriched by Ferulic Acid. This ingredient also shows anti-oxidative qualities. Ferulic acid also makes facial skin smoother and repairs UV-related skin damages.
  • For what this serum is able to deliver, it clearly sets itself apart as a great value deal.

Our No. 2: John Masters Serum

Best Vitamin C Serum No 2

  • “Expensive organic Premium Serum”
  • The manufacturer John Masters is known for its expensive organic premium-skin care products. The manufacturer goes the same way with the Vitamin C Serum: expensive while providing high quality.
  • The consistency is light, the serum can be well distributed and soaks in fast. The dark glass bottle protects the elixir from excessive sun, so that it keeps its caring effect longer! With plant essences and oils, the manufacturer pays attention to organic cultivation. This serum contains some of each – among the rest, are Aloe Vera extracts and sunflower oil.
  • On account of its richness, John Masters recommends its Vitamin C Serum even as a self-standing care for the evenings. Nevertheless, I could imagine that this might not be enough for the care of dry skin. In any case, nothing speaks against the use of a good night cream.
  • John Masters organic Serum is slightly sticky and is higher priced than the Instanatural Serum. Despite its effectiveness, it has not been enough to become our number one. However, for friends of organic cosmetics, this could very well be your first choice!

How is Vitamin C used in skin care?

Vitamin C is used most often in the concentrated form – starting at a concentration level of just 3%, it unfolds its skin care related qualities.

With rising concentration, its effectiveness rises as well up to a saturation point of about 15-20%. In addition it must be stated that it makes little sense to further raise the degree of Vitamin C in cosmetic products.

The most effective form of Ascorbic Acid preparations are Vitamin C Serums. Most of the time they contain the highest concentration of this active ingredient, in many cases they are further complemented by other skin caring ingredients. The main operational area of Vitamin C Serums is the anti-aging care of the facial skin area.

Vitamin C also finds its use in creams – mostly in a lower concentration. In creams it is mostly used for the regulation of moisture and the structural improvement of the protective barrier belonging to skin.



How can you improve the caring effect of Vitamin C further?

The effectiveness of Vitamin C cosmetics can be increased by the admixture of other ingredients. In the following, I will enter into some elaborations on the optimum form, concentration as well as on which substances and ingredients harmonize well with Vitamin C.

Type of application

Vitamin C care must generally be applied directly onto the skin. This ensures that the active ingredient can unfold its anti-aging function. However, vitamin-containing tablets show no skin-maintaining effect.

The most effective form of Vitamin C is, as previously stated, the Ascorbic Acid. All the other forms are chemically a little more stable, but do not function quite as intensive.


Concentration and durability

The concentration of Ascorbic Acid within the care product should amount to at least 3-5%. Starting from this level, one can seriously speak of an anti-aging effect of the Vitamin C.

Ascorbic Acid strongly reacts with oxygen and changes to a darker color due to oxidation. Hence, serums containing Vitamin C should not be exposed to direct sunlight. The surroundings also determine how long-lasting the serum is. The serum should possibly be kept in a cupboard or drawer and be used up within three months.

Useful additives in Vitamin C Serums

Vitamin C Serums often contain additional substances harmonizing well with Ascorbic Acid. Among them, the following substances can usually be found:

  • Vitamin E (strengthening of the anti-oxidative effect)
  • Vitamin A (Retinol Care)
  • Hyaluronic Acid (moisture care and strengthening of skin structures)
  • Ferulic Acid (treatment of wrinkles and strengthening of skin elasticity)
  • Other natural oils and plant essences

Conclusion of the Vitamin C Serum Review

Best Vitamin C Serum

Here are the summarized findings and results of our Vitamin C comparative test:

  • Vitamin C (Ascorbic Acid) is an important anti-aging ingredient.
  • Together with Retinol, Vitamin C belongs to the best researched skin care substances.
  • The inherent effect of any Vitamin C Serum lies primarily on anti-aging due to its ability to strengthen collagen production, moisture regulation, anti-oxidative UV protection as well as improving the skin’s natural barrier.
  • In addition, anti-inflammatory, bactericidal and skin-lightening qualities are also ascribed to Vitamin C.
  • At least 3-5% Ascorbic Acid are needed for a Vitamin C Serum to unfold its caring qualities on facial skin.


  • It is important that a Vitamin Serum contains other care related substances, such as Vitamin E, Hyaluronic Acid and Ferulic Acid. These ingredients harmonize well with Vitamin C and often strengthen its effectiveness.
  • Ascorbic Acid reacts quickly with the oxygen in the air. This is one way how Vitamin C Serum can oxidize and lose its care related qualities.
  • Therefore, it is important to keep the skin care serum in a dark, chilled area and to finish it up within three months.
  • Many scientific researches have proven that Vitamin C Serum is a mighty anti-aging instrument. What do you think about that? Your opinion is important to me, it would be greatly appreciated if you took the time to answer a small survey.
