If you are looking for vitamin C products for the skin, you will find countless products on the Internet. Unfortunately, it is not obvious to end consumers that some products have an inadequate effect and therefore hardly any effect at all. If you then decide on a product and only later find out about a better alternative, the frustration is great. In this buying guide, our editorial team from Apotheken-Warentest has compiled all the important criteria for assessing the products on the market and analyzed the test winner.
For years, vitamin C has been THE active ingredient that women around the world turn to when it comes to skin care. New studies have once again confirmed this: Vitamin C tightens the skin, can slow down skin ageing and increase resistance. It is said to reduce wrinkles by 40% after just a few weeks and make the skin smoother and softer. Vitamin C also provides antioxidants in the skin, protecting it from irritation, inflammation and environmental stress. Many users report enthusiastically: "I feel ten years younger!"
But caution is advised here too: There are also big differences in vitamin C serums! Scientists report that it depends on the composition and the method of application.
We uncover the biggest myths about vitamin C for you and show you what to look out for when buying. We have carried out independent research for you and selected the top 3 best vitamin C products. Our short guide will give you all the knowledge you need to never waste your money on worthless hyaluronic acid products again. So you can achieve maximum results.
Studies have long proven the effectiveness of vitamin C.
There are now many placebo-controlled studies that prove the visible effect of vitamin C. We present a small selection here:
1st Munich Study: Increased skin hydration and elasticity
A clinical study conducted by the Ludwig-Maximilians-University of Munich focused on the influence of creams containing a special vitamin C formula with a content of 1% including a mucilage active ingredient. The study observed 76 women and analyzed the elasticity and moisture content of the skin around the eye area. The results showed that the vitamin C serum used significantly increased skin hydration and elasticity compared to a placebo.
2. further Munich study: Reduced wrinkle depth after 3 months
In another clinical study with 20 participants, divided into four groups, different vitamin C products were tested for daily use. Wrinkle depth and skin firmness were measured before and after a 3-month application phase. The results showed that the depth of wrinkles was reduced by up to 20% after just 3 months and the skin was tightened by up to 30%.
3 University Hospital Basel: Slowing down the ageing process
A joint research project between the School of Medicine in Thessaloniki and the University Hospital Basel revealed back in 2012 that vitamin C in the form of a serum is able to slow down the ageing process.
As we have learned in the previous lines, vitamin C in serums has a good reputation in terms of its effect on the skin for justified and even scientifically confirmed reasons.
It can therefore be assumed that not only the best quality is used in the flood of vitamin C products.
To really benefit from the advantages of vitamin C, you should keep a few points in mind. You can read about these in the following section:
Criterion1: Serums are usually purer than creams and therefore the most effective
Criterion 2: The best results are achieved by channeling vitamin C deep into the skin
Criterion 3: Quality before quantity
We have analyzed dozens of scientific studies for you and tested the most promising products on this basis. Here we present the 3 best vitamin C serums and the test winner.
We have also based our assessment on the above criteria and included verified product reviews from female testers.

Vitamin C serum
This natural serum from KU2 Cosmetics is a simple, high-quality and versatile product with a concentrated amount of vitamin C. It helps to increase the skin's moisture and thus ensures more radiant skin.
The KU2 company is popular with beauty enthusiasts. Not least because all products have been developed in collaboration with cosmetic scientists. In addition, regular laboratory tests ensure that effectiveness and safety are guaranteed. The only drawback: although the product appears to be of high quality overall, we have found that some users report a rather sticky consistency. It often takes longer to fully absorb into the skin than comparable products.
