Supports smart aging
Goes beyond classic anti-aging. Supports cellular-level processes to help firm the skin and restore a look of youthful vitality.
Promotes cellular renewal
Contains RejuveNAD™ to help boost NAD⁺ — the longevity molecule essential for cellular energy. Addresses 5 of the 9 hallmarks of skin ageing.
Effective from the first use
In just 30 minutes: +36% hydration and +25% skin smoothness. After 28 days, participants agreed their skin looked its best.
Results confirmed by advanced testing
Intercellular is a next-generation longevity serum based on the latest discoveries in epigenetics and cellular metabolism. Its efficacy is confirmed not only by consumer in-use testing, but above all by independent instrumental testing — an objective way to measure real changes in the skin.
At the core of the formula is a combination of three pioneering longevity ingredients: RejuveNAD™, which helps boost NAD⁺ — the longevity molecule; pomegranate seed stem cells, rich in precursors of urolithin A; and Oio Lab Longevity Complex™, with spermidine supporting autophagy. This approach goes beyond standard anti-ageing formulas by targeting cellular-level processes.

What makes INTERCELLULAR different from a standard anti-ageing serum?
Wondering whether Intercellular is right for you? See how it differs from a standard anti-ageing serum. Built on cellular longevity research, it is designed to help maintain skin’s peak condition for longer.
| Feature | Standard anti-ageing serum | INTERCELLULAR — next-generation longevity serum |
|---|---|---|
| Skincare philosophy | Anti-ageing mainly focuses on reducing the visible signs of ageing. | Smart aging supports cellular longevity, helping maintain the skin’s peak condition for longer. |
| Mechanism of action | Mainly focuses on visible results, such as smoothing or hydration. | Draws on research in epigenetics and cellular metabolism. In a clinical assessment of RejuveNAD™, skin appeared up to 8 years younger on average. |
| Ingredient technology | Ingredients often focus on a single mechanism of action. | Three pioneering longevity systems: RejuveNAD™ to support NAD⁺ levels, pomegranate seed stem cells and Oio Lab Longevity Complex™ with spermidine to support autophagy. |
| Testing method | May rely mainly on user declarations. | Instrumental testing: +36% hydration and +25% smoothness after 30 minutes; +22% firmness and a 9% reduction in wrinkle depth after 28 days. |
| Formula and size | Usually 30 ml. | 50 ml of a lightweight, milky formula — more than a standard serum. |
| Natural origin | Often contains synthetic fragrance, additives and preservatives. | 99.2% ingredients of natural origin, free from synthetic fragrances and preservatives. |
What’s inside INTERCELLULAR longevity serum — and why it works?
Intercellular combines pioneering longevity ingredients with proven activity — supporting cellular energy, renewal and the skin’s ability to maintain its best condition for longer.
Here are the selected active ingredients that set the formula apart:
Derived from organic sunflower sprouts — a plant long associated with vitality, energy and renewal. The sprouts are cultivated through indoor farming, without soil or pesticides, in a carefully controlled process.
RejuveNAD™ is a next-generation botanical active that naturally boosts NAD⁺ — the longevity molecule essential for cellular energy, DNA repair and skin renewal.
Ingredient-level studies on RejuveNAD™ show activity across 5 of the 9 hallmarks of skin ageing. In a clinical assessment, skin appeared 8 years younger on average after 6 weeks, while measurements showed a 69% increase in collagen density.
COSMOS approved and NATRUE certified.

Obtained through sustainable cultivation from pomegranate seeds — a fruit long prized as a symbol of renewal and vitality. The active is rich in gallotannins and ellagitannins, precursors of urolithin A, one of the best-studied compounds in the field of healthy cellular ageing.
Unlike ingredients focused on a single effect, it works more comprehensively — helping brighten the complexion, even skin tone, protect against oxidative stress and support overall skin condition.
Ingredient-level studies confirm a 21% decrease in melanin levels, helping promote a more even tone and visibly brighter complexion.

An advanced complex developed in our Laboratory, combining three state-of-the-art active ingredients that support skin longevity:
— vegan collagen with spermidine, which supports autophagy — the skin’s natural cellular renewal process
— tuberose stem cells with betaine, which help improve microcirculation
— ultra-pure ozonated omega 3-6-9 esters from Polish linseed oil, which support the delivery of active ingredients deeper into the skin
Together, they support key cellular processes — autophagy, microcirculation and active-ingredient delivery — helping promote collagen synthesis, strengthen the protective barrier and leave skin looking firmer and more radiant.

Perfect
Love this product and will buy more bottles in the future. Skin looks absolutely gorgeous after using it!
Elena
I started using the intercellular serum after the summer, in combination with Superpause and O-mega Milk, which I use both as a cleanser and occasionally as a mask. Since then, my skin has looked consistently healthy and balanced, even and dense. I receive compliments on my skin all the time now. It has truly been a game changer.
Marjorie
Great product
I’ve been using this serum for a couple of weeks, and I can already see a difference. My skin feels fresh, hydrated, and my skin tone looks much more even. I’ve also purchased some other products from Oio Lab, and I love them all.
Ekaterina Margulis
Love it!

Maria
wonderful serum
Wonderful serum. Instantly makes the skin soft and tender. Pleasant to apply like all products from oiolab. Have all products from you. An eye cream and a washing gel or scrub would be great.
EDDA
Soothing, Hydrating & Firming
This new serum is just beautiful! It adds some extra hydration to my, sometimes dehydrated, skin and really makes my face look and feel tighter and firmer. It's a nice addition to Oio's excellent and effective serum family.

FAQ
A longevity serum is a next-generation approach to skincare designed to support skin’s long-term condition — not only smooth the surface. Intercellular is built around cellular longevity, combining RejuveNAD™, pomegranate seed stem cells and the Oio Lab Longevity Complex™ to support cellular energy, renewal and lasting skin vitality.
NAD⁺ is often called the “longevity molecule” — a coenzyme that plays a key role in cellular energy and DNA repair. Its levels naturally decline with age, which can be linked to slower renewal and a more tired-looking complexion. In Intercellular, RejuveNAD™ helps support natural NAD⁺ levels in the skin, helping it look energised, resilient and in peak condition for longer.
RejuveNAD™ is a next-generation botanical active derived from organic sunflower sprouts. It helps boost NAD⁺ — a molecule essential for cellular energy and renewal. Ingredient-level studies on RejuveNAD™ show activity across 5 of the 9 hallmarks of skin ageing; in clinical assessment, skin appeared, on average, up to 8 years younger.
Intercellular combines three longevity systems: RejuveNAD™ to help support natural NAD⁺ levels in the skin, pomegranate seed stem cells with urolithin A precursors, and the Oio Lab Longevity Complex™ with spermidine. Together, they support cellular energy, renewal and the long-term quality of the skin.
