Vitamin C Tetra is a new and highly effective, extremely stable and at the same time gentle form of vitamin C which penetrates more deeply into the skin. It effectively protects the skin from UV damage, stimulates collagen production and reduces fine lines, wrinkles and hyperpigmentation.


Astaxanthin, extracted from red phase algae, is considered one of the most powerful antioxidants in the world. It neutralises free radicals and inhibits the breakdown of collagen.


Organic Gotu Kola extract helps reduce inflammation and promotes collagen production. Due to the high content of lutein, Gotu Kola effectively protects against blue light. This Asian medicinal plant is one of the most important adaptogens in Ayurveda and TCM.


Organic ginkgo, a powerful adaptogen from TCM, protects the skin from the negative effects of blue light, has a strong anti-inflammatory effect and strengthens the skin barrier.


Cold-pressed organic plum seed oil provides the skin with valuable fatty acids and minerals, is rich in vitamin E as well as provitamin A, and has an exceptionally powerful antioxidant effect.


Squalane from sustainably grown organic sugar cane intensively nourishes the skin with valuable fatty acids, provides long-lasting moisture and gives incredible suppleness. Our squalane is a certified organic ingredient and supports a healthy microbiome.

The Adaptogen Vitamin C Oil Serum can be applied in the morning and/ or evening:

  1. Thoroughly cleanse your skin.
  2. Moisten your skin with water or a mild toner such as rose water. The oil serum should be applied onto slightly damp skin, enabling it to best soak into your skin.
  3. Now apply 4 to 5 drops of the oil serum onto your damp skin.
  4. Massage the oil serum gently into your skin. After just a few minutes, the oil serum has completely soaked into the skin. Enjoy your silky-smooth and glowing skin!

Tip: You can also use the Adaptogen Vitamin C Oil Serum as an active-ingredient booster. Just add a few drops of the oil serum to your favourite skincare product.


When is the best time to use The Adaptogen Vitamin C Oil Serum?

Ideally, our Adaptogen Vitamin C Oil Serum should be applied in the morning, as the vitamin C tetra contained within the serum has been proven to protect the skin from UV radiation*. The oil serum also contains powerful adaptogens and antioxidants that protect the skin from blue light, making our Vitamin C Oil Serum the ideal everyday companion.

In which step of my beauty routine do I use The Adaptogen Vitamin C Oil Serum?

Our Adaptogen Vitamin C Oil serum is best applied after toner and water-based serums, such as a hyaluronic acid serum. This allows the oil serum to optimally lock in the moisture previously added. No cream needs to be used afterwards, as the squalane contained in the serum is rich and nourishing but doesn’t weigh the skin down.

Is The Adaptogen Vitamin C Oil Serum suitable for sensitive skin?

Yes! Our Adaptogen Vitamin C Oil Serum is ideal for sensitive skin because it is mildly formulated and contains no alcohol, preservatives, fragrances, essential oils or other potentially irritating ingredients. The ingredients used have been proven to strengthen the skin barrier, protecting and soothing sensitive skin. In addition, vitamin C tetra is exceptionally well tolerated and does not irritate the skin, as is often the case with ascorbic acid, also known as pure vitamin C. 

ruhi TIP: We always recommend that you test a new skincare product on a small area of your skin before adding it to your skincare routine. This way, you can easily rule out an allergic reaction to any of the ingredients.

Why do you use a clear bottle for The Adaptogen Vitamin C Oil Serum?

Unlike pure vitamin C (ascorbic acid) and other derivatives, the vitamin C tetra we use in our formula is one of the most stable forms of vitamin C and is perfectly able to withstand changes in temperature and oxidation levels.

Scientific studies have shown that vitamin C tetra is even stable up to 250°C (!)**. Therefore, we can use a transparent bottle without any problems (unlike ascorbic acid, which is very sensitive to oxidation and should only be filled in amber glass).

Why does The Adaptogen Vitamin C Oil Serum cost more than the other serums?

Vitamin C tetra is an innovative, oil-soluble vitamin C derivative that comes at a much higher price point than ascorbic acid, which is affordable and straightforward to source. We also use a high concentration (15%) of vitamin C tetra. Therefore, the pure product price of our vitamin C serum is higher—especially compared to other products that often contain only 1% of the active ingredient.

"A vitamin C serum is an absolute must-have product in my slow-ageing routine, alongside other products like a nourishing facial oil. Luckily, our Vitamin C Oil Serum combines both—it is a potent, collagen-building vitamin C serum and an ultra-nourishing facial oil all in one product. This multi-use functionality allows me to combine two steps of my morning routine into just one and start the day more at ease.

The Vitamin C Oil Serum is also my ideal everyday companion because it not only protects my skin from UV radiation but also from blue light when I'm sitting in front of the laptop all day*. Plus, it's anti-inflammatory and restores my often-stressed-out skin to its healthy balance—all with just a few, hand-picked ingredients of the highest quality in a minimalist formulation."

Have fun with it,

Absolut bestes Vitamin C serum seit langem

Ich habe schon sehr viele verschiedene Serums ausprobiert, da ich Make up Artistin bin und somit viele verschiedene Produkte kennenlerne.
Doch dieses Wunder Produkt ist bis jetzt, mit Abstand das Beste, meine Haut ist so sanft wie noch nie, Pigment Störungen sowie unreine Haut, haben sich in kürze verbessert - ich bin wirklich sehr begeistert 🙏🏼❤️

Yurdagül Bayram

Sehr begeistert. Sehr geschmeidig fühlt sich angenehm auf der Haut an.Haut wirkt frischer rosiger ! Habe auch das Hyaluron in Kombination auch alleine sehr angenehm frisch und leicht auf der Haut

Ich hätte mehr Pflege erwartet

Meine Haut ist nicht genug durchfeuchtet. Vielleicht muss ich mir das Hyaluron serum zusätzlich bestellen und in Kombination benutzen...

Liebe Fabiola,
vielen Dank für dein ehrliches Review. Unser Oil-Serum ist auf Squalanöl-Basis formuliert. Wichtig ist, das Öl-Serum immer auf leicht feuchte Haut aufzutragen, da Öle nicht direkt Feuchtigkeit spenden, sondern die in der Haut vorhandene Feuchtigkeit einschließen und hierdurch quasi indirekt für eine optimal durchfeuchtete Haut sorgen. Wenn deine Haut jedoch sehr trocken ist, macht es in der Tat sehr viel Sinn, das Hyaluronserum oder unser Toner-Serum darunter aufzutragen. Beide Seren sind extrem feuchtigkeitsspendend, da sie auf Bio-Aloe-Vera-Saft-Basis formuliert sind. Wenn du darüber dann das Öl-Serum aufträgst, wird diese Feuchtigkeit in der Haut optimal eingeschlossen. Ich mache das auch so und habe den ganzen Tag über wunderbar hydrierte, babysofte Haut. (48 Jahre, inzwischen eher trockene Haut). Solltest du dennoch nicht happy mit dem Öl-Serum sein, sende es uns gerne innerhalb von 30 Tagen zurück und wir erstatten den vollen Kaufbetrag.
Liebe Grüße

Samtweiche Haut

Ich benutze das Vitamin c Oil Serum jetzt seit 1 1/2 Monaten, zusammen mit dem Hyaluronserum und dem Bakuchiol Serum. Ich vertrage alles sehr gut. Zu meiner Routine gehören inzwischen auch ein Gua Sha Stein und die Kupferbürste für Gesicht und die für den Körper. Alles zusammen beschert mir eine samtweiche, gepflegte Haut ohne Irritationen. Wenn bei den angekündigten neuen Produkten jetzt noch eine Augenpflege und ein Reinigungsöl dazukommen wäre das Pflege Glück perfekt. Bin sehr zufrieden mit den Produkten.

Vitamin C Serum

Für mich das beste für meine reife Haut. Deshalb habe ich es jetzt zum zweiten Mal bestellt. Auch die anderen Produkte überzeugen mich sehr. Ich wünsche mir noch ein Reinigungsprodukt um die Pflege zu komplettieren.
