THIS is our editor’s skin in 1998, and THIS is what she looked like in January 2023.
Can you spot the difference?
You might think she lived an unhealthy life or started smoking during this time.
But that’s wrong. Her lifestyle didn’t change in those years.
She simply enjoyed the sun and even applied sunscreen every day.
Despite this, her pigmentation spots got worse and worse.
But now, two months later, her skin looks even again.
This is because she started using this vitamin in 3 simple steps.
She was able to transform her age spots. And achieve something even greater…
The #1 vitamin for healthy skin
No other vitamin is better for the skin than vitamin C.
It protects against premature ageing and revitalises your skin from the inside out.
But only if you follow these 3 simple steps.
Otherwise, there are many reasons why you may be disappointed with the results.
That’s why we’ve put them together for you here.
But let’s start with…
3 studies on the effect of vitamin C on our skin
The effects of vitamin C on our body have long been researched.
And although it is important for our immune system, it plays a crucial role in our skin health in particular.
There are thousands of studies on its effectiveness and we have selected 3 significant ones for you.
1. age spots could be visibly lightened after 8 weeks (Korean study) 1
2. the development of pigmentation spots was significantly slowed down (French study) 2
3. vitamin C offered immediate protection against premature skin ageing caused by UV radiation (American study) 3
Which vitamin C product is right for you?
To summarise briefly: science shows that vitamin C can transform your skin.
But whether the various manufacturers also offer effective products is a completely different question.
That’s why I would now like to show you what you should look out for when buying vitamin C products.
3 important criteria for vitamin C to work as hoped
1. was it a serum or a cream?
When it comes to getting active ingredients deep into the skin, a serum has an advantage over a cream for the following reasons:
- In a serum, the active ingredient molecules are significantly smaller, allowing them to penetrate into deeper layers of the skin. As a result, they act on the area where pigmentation spots occur, whereas a cream only cares for the surface of your skin.
- A serum can be applied in higher doses because its lighter consistency makes this possible. It therefore has a stronger effect and leads to the desired result more quickly.
2. what was the vitamin C concentration?
If you want your serum to deliver what it promises, opt for a vitamin C concentration of at least 10%.
According to studies, the effectiveness of a lower concentration is greatly reduced because it is not sufficient to stimulate significant changes in the skin. 4
Optimum results can be achieved after a few weeks with a concentration of 20% – anything above this would be a waste.
3. what type of vitamin C was used?
There are several forms of vitamin C, known as derivatives, which differ from conventional ascorbic acid.
Especially in skin care products, these alternatives can sometimes even be more effective.
However, this is not the most important reason to use them:
Some derivatives are much more stable than original ascorbic acid. This means that they do not lose their effect because they are exposed to air for too long or because of their sensitivity to light.
The most potent of these alternative types is 3-O-ethyl ascorbic acid because it is also suitable for sensitive skin and is particularly effective against pigmentation spots.
The big vitamin C test 2023: Which serum is the best?
After extensive research and discussions with experts, we still had 43 vitamin C serums left in our editorial team – all of which had to be tested.
In our evaluation, we took the above criteria into account, listened to what scientific studies told us and looked at verified customer reviews.
Our top 5 of the big vitamin C serum test 2023
Now you know what to look for when choosing an effective vitamin C serum.
But which one is right for you?
To help you with this decision, we have compiled the top 5 vitamin C serums here.
Good to know: In terms of effect, 1st and 2nd place are on a par. However, they differ significantly in price.
1st place: The Pure Glow Booster for radiant skin without pigmentation spots
This serum has more than earned its place as the test winner. In terms of effectiveness and tolerability, it was able to prevail in a direct comparison against 42 vitamin C products and convince our editorial team.
My colleague was actually supposed to put the Pure Glow Booster to the test. She did and after just 14 days she simply couldn’t stop raving about it.
After countless product tests with rather modest results, I couldn’t help but put it at the top of my test list.
And it didn’t promise too much. The mottled texture of my skin disappeared after just a few weeks. For the first time, I can feel what people have always meant by “glowing” skin.
My face also feels firmer and especially the wrinkles around my eyes are much less visible.
Not only does this serum have a noticeably more powerful effect than anything I’ve tried before, but it also delivers faster results with daily use.
In my opinion, this is only possible due to the quality of the concentrated vitamin C (20%). Together with powerful antioxidants such as chlorophyll, it protects the skin and cares for it with 100% natural ingredients without irritating fragrances or colours.
What we liked
- Very effective for lightening pigmentation spots
- Skin-firming and nourishing effect
- Easy to tolerate – even for sensitive skin
- Price/performance ratio
- High quality ingredients
- Fast DHL shipping from Germany (usually delivered in one day)
- Unconditional 60-day money-back guarantee
What could be improved
- Unfortunately sold out at times due to high demand
- Only available online or in selected pharmacies
2nd place: 20% Vitamin C Brighten + Firm Serum from Allies of Skin
Just like our number 1, this serum impressed us with its potent formula.
After using it daily for several weeks, we were able to achieve a visibly more even complexion. It felt gentle on the skin and absorbed quickly without leaving any residue or irritation.
This serum also contains a concentration of 20% 3-O-ethyl ascorbic acid and antioxidants in the form of orange extract. This makes it effective against age spots and protects the skin from harmful environmental influences.
However, it only came second in our test because, although it can achieve the same impressive skin results as our test winner, at EUR 106.00 it is almost three times as expensive.
What we liked
- Very effective for lightening pigmentation spots
- Nourishing effect against fine lines
- Easy on the skin
- High-quality ingredients
What could be improved
- High price
- Short manufacturer’s guarantee
- Condition for free shipping (75€)
3rd place: C E Ferulic from SkinCeuticals
The results we were able to achieve with C E Ferulic were quite convincing.
This serum was not far behind 1st and 2nd place. However, we have a few things to criticise about this formula, which is why it was “only” good enough for third place.
Instead of a long-lasting derivative, the C E Ferulic contains L-ascorbic acid, which loses its effectiveness over time (even though the serum is packaged extra opaque).
As it also has a particularly high price, we think this position in our ranking is appropriate.
What we liked
- Very good effect for an even complexion
- Trusted by a well-known brand name
- Available online and in shops
- Free shipping within 3 days
What could be improved
- The shelf life of the formula
- Potentially problematic for sensitive skin
- Questionably high price
4th place: Vitamin C Face Serum from TruSkin
This serum contains a balanced blend of vitamin C, plant-based hyaluronic acid, vitamin E, aloe vera and jojoba oil.
A more stable type of vitamin C has been used (sodium ascorbyl phosphate), but both the effect and the skin tolerance could not compete with the alternative of our top contenders.
The formula feels pleasant on the skin and does not contain perfume, parabens or harmful chemicals.
What we liked
- Holistic skin care approach
- Perfume free
- Alternative active ingredients
What could be improved
- High shipping costs to Germany
- May not be suitable for sensitive skin
5th place: Vitamin C Plus E Serum from Timeless Skin Care
The Vitamin C Plus E Serum from Timeless Skin Care is quickly absorbed by the skin and leaves no residue.
And even though we definitely felt an effect, the brightening effect against pigmentation spots in particular could not keep up with the frontrunners on our list.
This is partly due to the fact that this formula contains “normal” vitamin C, which is unfortunately also inferior to the other products on our list when it comes to durability.
However, the manufacturer does not use animal testing or questionable chemicals.
What we liked
- Vegan and free from animal suffering
- Free from perfume and artificial fragrances
What could be improved
- Price/performance ratio
- Can further aggravate oily skin according to the manufacturer
There is one more thing to clarify…
Where can you get the test winner at the best price?

Q&A – Frequently Asked Questions
Should I use the Pure Glow Booster in the morning or in the evening?
You can use the Pure Glow Booster both in the morning and in the evening. It works through regular daily use, not at a specific time.
However, if you want to spend the whole day in the sun, you can benefit from applying the serum under your sunscreen.
How long do I need to use the serum before I see results?
According to studies, most vitamin C serums work after 4-12 weeks of daily use.
We were able to achieve clearly visible results with the Pure Glow Booster after just 4 weeks.
Isn’t it enough to simply eat vitamin C?
The application of vitamin C on the surface of the skin is important so that it can work where it is needed.
If you take in vitamin C with food, your body uses it for all sorts of things. The focus on the problems of the skin is lost.
What age group is the Pure Glow Booster suitable for?
There is no minimum age. However, if you don’t have any specific problems with hyperpigmentation, it makes sense to use it from the age of 25 (even if it plays more of a preventative role here).
The best results are achieved by users aged 40, 50 and even 60, as the Pure Glow Booster gives back to the skin what is lost over the years.
Does the serum lose its effect quickly if it is packaged in glass? No.
Only conventional vitamin C (ascorbic acid) is sensitive to light and can oxidise if it is exposed to air for too long.
In the Pure Glow Booster, a more stable form (3-O-ethyl ascorbic acid) has been used, with which these problems do not occur.
