Vitamin C has been the active ingredient used by women all over the world for years when it comes to skin care. Recent studies have once again confirmed that vitamin C improves the skin, reduces cutaneous fatigue and increases skin resistance. As a result, the rashes will be reduced by 40% in just a few weeks and the skin will become lighter and thinner. In addition, vitamin C acts as an antioxidant in the skin, protecting it from irritation, inflammation and environmental aggression. Many users report with enthusiasm: "I feel six years younger! "

However, it is important to be careful: there are also major differences between vitamin C supplements! Scientists report that everything depends on the composition and the method of application.

We've analyzed the biggest myths about vitamin C for you and show you what you should pay attention to when buying. We have independently researched for you and compiled the top 3 best vitamin C-based products. With our short guide, you will gain all the necessary knowledge to never again waste your money on products based on hyaluronic acid without value. In this way, you can achieve maximum results.

Studies have long proven the efficacy of vitamin C.

There are now a number of placebo-controlled studies that show the visible effect of vitamin C. We present a brief summary here:

Étude de Munich : Augmentation de l'hydratation de la peau et élasticité accrue

A clinical study carried out by the Ludwig-Maximilian University of Munich focused on the influence of creams containing a special formulation of vitamin C with a concentration of 1% and an agent facilitator. The study observed 76 women and analyzed the elasticity and hydration of the skin around the eye area. The results showed that in comparison with a placebo, the vitamin C serum used resulted in a significant increase in skin hydration and elasticity.

Autre étude de Munich : Réduction de la profondeur des rides après 3 mois

In another clinical study with 20 participants, divided into four groups, different vitamin C-based products for daily use were tested. Before and after an application period of 3 months, the depth of the rides and the fermeté of the skin were measured. The results showed that the ride depth was reduced by up to 20% after just 3 months and that the skin was reduced by up to 30%.

Hôpital universitaire de Bâle : Ralentissement du processus de vieillissement

A collaborative research between the École de médecine de Thessalonique and the Hôpital universitaire de Bâle revealed in 2012 that vitamin C in the form of serum is capable of slowing down the aging process.

As we have seen in the previous paragraphs, vitamin C in syrups has an excellent reputation due to its scientifically proven effects on the skin.

Thus, one can assume that, despite the multitude of vitamin C-based products available, they are not all of the best quality.

To really benefit from the advantages of vitamin C, you need to keep a few things in mind. You can read them in the following section:

Critère 1 : The serums are generally more pure than the creams and are therefore more effective.

Critère 2 : Les meilleurs résultats sont obtenus lorsque la vitamine C est efficacement acheminée en profondeur dans la peau.

Critère 3 : La qualité avant la quantité.

We have analyzed dozens of scientific studies for you and tested the most popular products on this basis. We present here the 3 best vitamin C supplements as well as the winner of the test.

We also based our evaluation on the criteria mentioned below and took into account the verified opinions of the testers.

Ce sérum naturel de KU2 Cosmetics est un produit simple, de haute qualité et polyvalent avec une quantité concentrée de vitamine C. Il aide à augmenter l'hydratation de la peau, ce qui la rend plus éclatante.

The KU2 company is popular among beauty enthusiasts, especially because all its products are developed in collaboration with specialized cosmetic scientists. In addition, regular laboratory tests guarantee efficacy and safety. The only drawback: although the product appears to be of high quality overall, we have found that some users report a very low resistance. It often takes more time than comparable products to be completely absorbed by the skin.
