This unique treatment, designed by the Novexpert Doctors, is compatible with all skin types, even sensitive ones.

Demanding approach born out of necessity.

Our requirement is a daily constraint but a guarantee of effectiveness for you: no Novexpert product will be released unless it is effective and different from what already exists on the market.

PROBLEM N°1: 1 in 2 people lack vitamin C!

99% of mammals are capable of producing Vitamin C, except monkeys, guinea pigs, and… humans. Today, more than 50% of the population does not meet their Vitamin C needs.

OUR SOLUTION

30% stabilized vitamin C in a single bottle, nearly 10g. One of the highest concentrations on the market, providing the skin with the significant amount of vitamin C it needs every day.

PROBLEM N°2: a fragile vitamin C!

Classic vitamin C, ascorbic acid, is unstable. It is extremely fragile and sensitive to heat and light: -60% of classic vitamin C after 1 month at 45°C*.

OUR SOLUTION

A unique, ultra-stable Vitamin C complex, formulated by Novexpert Laboratories where Vitamin C is bound to 2 "bodyguard" molecules that ensure ultra-high stability and excellent penetration. Stability is 40 times greater compared to regular Vitamin C*.

PROBLEM N°3: an irritating vitamin C!

Many vitamin C treatments can make the skin more sensitive to the sun and cause irritation when exposed to sunlight, due to their composition (fragrance, essential oil) or their acidity (pH around 3).

OUR SOLUTION

First ultra-concentrated vitamin C serum: - certified non-photosensitizing, no reaction when exposed to sunlight - usable in all seasons, even summer - suitable for all skin types, including sensitive skin

PROBLEM N°4: accelerated aging.

Few people know this, but Vitamin C is truly an anti-aging vitamin. Without it, there is no collagen synthesis, leading to hollowed, sagging skin that ages faster.

OUR SOLUTION

A deeply anti-aging treatment with a vitamin C that stimulates collagen production twice as much as regular vitamin C. 71% of users find their skin firmer after just 1 week*.

PROBLEM N°5: dull complexion.

The face is on the front line against oxidizing molecules released by UV rays or pollution. Daily antioxidant protection is essential to reduce dull complexion and premature aging.

OUR SOLUTION

The Vitamin C Booster Serum provides antioxidant effectiveness for 8 hours*, an essential shield to restore radiance and protect cells from premature aging.

Our scientific differences

Scientific difference No. 1

Next-generation Vitamin C: 40X more stable

Wanting to preserve classic vitamin C within a skincare product is to fight against its very nature. Conventional ascorbic acid is very fragile: just one month at 45°C (equivalent to 6 months at room temperature) is enough for 60% to be completely destroyed*, making it unusable. The Novexpert Doctors change the game by using a vitamin C complex with exceptional stability – 40 times more stable than conventional vitamin C*. Integrity preserved over time for guaranteed effectiveness from the first to the last use.

In the photos: Browning color = Vitamin C degrading.

Scientific difference No. 2

Care usable 24/7 and 365 days a year, even in the sun

In cosmetics, highly active vitamin C formulas often require a trade-off between effectiveness and tolerance. With this treatment, Novexpert Laboratories make no compromises. The new Vitamin C Booster Serum is certified:

non-photosensitive

non-phototoxic

non-photoallergenic

It can be used in all seasons, especially in summer, when the skin needs even more vitamin C because sun exposure can increase oxidation by 20 times. A treatment usable all day, all year round, for all skin types, even sensitive ones.

Scientific difference No. 3

This serum respects the natural functioning of the skin and uses the skin's biological mechanisms to make the two actions of vitamin C visible in the skin: radiance and anti-aging.

Radiance: Brighten the complexion by supporting the antioxidant system.

Oxidizing molecules damage proteins, which is called carbonylation. These proteins clump together and form an opaque haze beneath the epidermis. While healthy skin acts like a crystalline surface that reflects light, these protein clusters function like blotting paper: they "absorb" light instead of scattering it.

The result? A dull complexion that turns grayish. The stabilized Vitamin C in the Booster Serum fights against this carbonylation by neutralizing 93% of free radicals*. It works in synergy with the skin's antioxidant enzymes. Its antioxidant effectiveness has been proven for 8 hours.

Anti-aging: stimulates skin collagen synthesis.

Vitamin C is the key to unlocking collagen synthesis. Without it, these precious fibers that provide elasticity and firmness cannot form.

The stabilized vitamin C from Laboratoires Novexpert stimulates collagen production twice as much as ascorbic acid*. Fibroblasts, the skin cells, recognize it and use it to create collagen.

Scientific difference No. 4

Not all vitamin C supplements are the same.

Novexpert quality guarantee: a vitamin C for everyone, in every season, effective from the first to the last use.

Quality criterion no.1

A vitamin C for everyone, suitable for all skin types, even sensitive skin. Unlike classic vitamin C, ascorbic acid, the Novexpert vitamin C complex is stable at a pH close to physiological pH. This allows the formulation of treatments for all skin types, not too acidic, which can be used by sensitive skin.

Quality criterion no.2

High stability for effectiveness from the first to the last use. The stabilized vitamin C chosen by Novexpert Doctors is 40 times more stable than the classic form*. Essential integrity to ensure the treatment’s effectiveness.

Quality criterion no.3

One of the goals of vitamin C is to stimulate collagen for visible and lasting anti-aging effects. Novexpert’s vitamin C is 2X more effective at stimulating collagen than ascorbic acid*.

Quality criterion no.4

Skin penetration for at least 8 hours* for a gradual supply of vitamin C. Skin cells are not saturated, and the active ingredient’s use is optimal.

When and how to use it?

How to use it?

The Experts' Council

Sunlight destroys vitamin C in the skin, which causes premature aging. Unique and convenient, the Booster is compatible with sun exposure (but does not protect against UV rays – no sunscreen filters). It can therefore be applied under your sunscreen.

Our ingredients

Derived from scientific studies and selected by our laboratory after 3 years of research.

Novexpert Vitamin C Complex

Benefits: radiance, anti-aging & anti-spot A unique complex of vitamin C linked to 2 "bodyguard" molecules that guarantee: - ultra-high stability - 40 times more than regular vitamin C*. - optimized penetration and diffusion over 8 hours - a treatment certified as non-photosensitive, non-phototoxic, and non-photoallergenic.

Ellagic Acid (birch extract)

100% natural plant extract containing ellagic acid. It increases the use of vitamin C by collagen factories*, the fibroblasts, by more than 40%. A synergy that boosts the anti-aging effect of vitamin C. An active ingredient also selected for its antioxidant power: -42% free radicals*, to prevent dull complexion and rough skin.

Novaxyline

A patented anti-aging complex made of an algae extract and a prebiotic, which slows cellular aging epigenetically. Novaxyline helps cells stay young longer by increasing sirtuins, anti-aging proteins, by 20% and reducing senescent cells by more than half.

Hyaluronic acid

High molecular weight hyaluronic acid (1000-1400 kDa) for a hydrating and plumping effect in just 30 minutes. The skin is hydrated, smoother, and reflects light better, which helps to brighten the complexion.

Adenosine

A globally recognized anti-aging active ingredient, adenosine stimulates the synthesis of collagens, especially types I and III, which are abundant in the skin, and may protect these valuable fibers from degradation. It is also a key factor in good hydration through its action on aquaporins, proteins that transport water within the skin.

Bisabolol

Targeted anti-spot active, it has demonstrated its ability to reduce melanin production - the pigment causing spots - in several scientific studies. The application of bisabolol is known to significantly brighten the complexion.

Glucosyl Hesperidin

Boosts radiance by stimulating blood circulation and protecting skin cells from oxidation, up to +45% oxidation. Hesperidin can also fade spots by acting on melanin production. A synergistic action with Vitamin C.

FAQ

What is a Vitamin C serum?

At Novexpert, a Vitamin C serum is a treatment with a fluid texture, ultra-concentrated in vitamin C. It offers two main benefits: radiance/even complexion thanks to the antioxidant power of vitamin C and anti-aging benefits, as vitamin C is essential for collagen synthesis. The Vitamin C Booster Serum is suitable for all skin types, even sensitive skin.

Why is vitamin C such an important active ingredient for the skin?

Because it’s not just about glow. Often forgotten, vitamin C has 3 clinically proven benefits: radiance, anti-dark spots & anti-aging. RADIANCE: it helps the skin fight oxidation and limit the accumulation of oxidized proteins on the skin surface. Result: skin that reflects light better, more luminous, more radiant. ANTI-DARK SPOTS: it limits the production of the pigment responsible for dark spots: melanin. ANTI-AGING: it triggers collagen production, the fibers that allow the skin to maintain elasticity and firmness. An essential vitamin that the skin cannot produce on its own and therefore must be supplied in large amounts.

Why did we reformulate our Vitamin C Booster Serum?

Because science advances. For us, reformulation never follows a trend. It answers one question: can we do better for the skin? Today, more than 60% of the population does not meet their vitamin C needs… Yet vitamin C is 100 to 1000 times more concentrated in the skin than other vitamins (A, E, etc.). It is therefore crucial to provide a large amount of vitamin C to the skin. The Novexpert Doctors, in collaboration with the laboratory, conducted hundreds of tests before finding the stable and balanced formulation to include 30% stabilized vitamin C. Moreover, the chosen form of vitamin C is delivered over time to skin cells for more than 8 hours. Like a “drip” of vitamin C that delivers its benefits to cells without saturating them.

What does 30% stabilized vitamin C mean? And why choose this form of vitamin C?

The stabilized vitamin C from Novexpert Laboratories is a unique form of vitamin C: more stable, highly tolerable, and more anti-aging than classic vitamin C, ascorbic acid. Within the complex chosen by the Novexpert Doctors, vitamin C (ascorbic acid) is linked to another molecule, a “bodyguard” that makes it more stable and allows easy penetration. The two molecules are “attached” together, grafted, and once in the skin, they separate to exert their respective benefits. This process allows vitamin C to be: MORE STABLE = Novexpert’s vitamin C complex is 18 times more stable than conventional vitamin C. MORE UNIVERSAL = Novexpert’s stabilized vitamin C is stable at a pH close to physiological pH, allowing treatments to be used by all skin types, even the most sensitive. MORE DURABLE = vitamin C is gradually separated from its “bodyguard” molecule in the skin. Skin cells therefore benefit from a continuous supply of vitamin C for at least 8 hours. MORE EFFECTIVE = stabilized vitamin C boosts collagen production twice as much as ascorbic acid. A doubly more effective anti-aging action.

Can our vitamin C serum be used in the sun?

Yes, and this is unique. Novexpert Laboratories’ Vitamin C Booster Serum is the first ultra-concentrated vitamin C serum certified non-photosensitive, non-phototoxic, and non-photoallergenic. This non-photosensitive certification is not just a detail. It is essential. UV rays can destroy up to 80% of vitamin C, while vitamin C protects cells from damage caused by free radicals generated by sun exposure. The Vitamin C Booster Serum can therefore be used 24/7, 365 days a year, even in summer when sunlight is strong. Our advice: get into the habit of applying it before your sunscreen for enhanced cellular protection.

Is it suitable for sensitive skin?

Yes. We formulated this serum to be compatible with all skin types, even sensitive skin. Its high tolerance is an integral part of our formulation standard. This is partly due to its pH, which is close to physiological pH. For us, performance must be accessible to everyone, even sensitive skin.

Is it suitable for pregnant and breastfeeding women?

Yes, all Novexpert products are 100% compatible with pregnant and breastfeeding women, including the Vitamin C Booster Serum. This is not just advice but a real certification.

Does vitamin C help reduce pigmentation spots?

Yes. Vitamin C is an excellent radiance active ingredient but also a spot-correcting active. It acts on melanin formation, the pigment responsible for spots when produced in excess. Novexpert’s stabilized vitamin C reduces by 47% to 72% the activity of molecules involved in the creation of this pigment. A real asset for an even complexion and reduced spots. The Vitamin C Booster Serum is even certified as a “therapeutic treatment” for dark spots in Korea, thanks to the actives it contains.

Is vitamin C also an anti-aging active ingredient?

Absolutely. Without vitamin C, no collagen. Vitamin C is essential for the synthesis of precious collagens; it is the key that unlocks their production. Collagens are the fibers that provide firmness and elasticity to the skin. Without them, the skin gradually loses firmness and density, and wrinkles deepen. But not all vitamin C is equal. Novexpert’s stabilized vitamin C demonstrates superior bio-affinity with fibroblasts (collagen factories): it stimulates natural collagen synthesis in the skin twice as effectively.

What differentiates our Vitamin C Booster Serum from a classic vitamin C serum?

Three main points: its concentration, stability, and tolerance. CONCENTRATION: 30% stabilized vitamin C in a single bottle, nearly 10g. One of the highest concentrations on the market, to provide the skin with the significant amount of vitamin C it needs daily. STABILITY: 40 times more stable compared to classic vitamin C. TOLERANCE: the first ultra-concentrated vitamin C serum certified non-photosensitizing, usable in all seasons including summer, compatible with all skin types, even sensitive. And of course, like all Novexpert products, its radiance and anti-wrinkle efficacy has been proven in clinical studies under medical supervision.

How long does it take to see the effects?

Radiance is one of the first benefits noticed. According to clinical studies conducted under medical supervision, 75% of volunteers found their complexion more radiant immediately after application and 85% found their skin more luminous after 7 days. The Vitamin C Booster Serum provides a real “healthy glow” effect (less gray, rosier complexion) for 80% of users. Regarding anti-aging, especially the reduction of wrinkles and fine lines, it is a biological mechanism that takes longer. A wrinkle can take 5 years to form, so it’s understandable that reducing it in a few days is difficult. However, in less than a month, a reduction of up to 42% in wrinkle volume is observed.

Can our vitamin C serum be used every day?

Yes. Our Vitamin C Booster Serum was designed for daily use. It integrates easily into a morning and/or evening routine, depending on skin needs. It is compatible with all skin types, even sensitive. For dry skin, we recommend applying a cream afterward for even more comfort. It is formulated for everyone: men, women, pregnant and breastfeeding women, and all ages.

How to properly apply our Vitamin C Booster Serum?

We recommend applying it on clean skin, morning and/or evening. It can be used alone if your skin is combination to oily, or before your cream if your skin is normal to dry. It integrates perfectly under sun protection. We especially recommend it in polluted environments, for outdoor work/sports, chronic stress, etc.
