Hyaluronic Acid Booster Serum

Hyaluronic acid is naturally produced by the skin.

But with age, its presence decreases: -50% by age 50, and an almost empty supply in the epidermis by 75 if nothing is done... On the surface, the skin hollows out, dehydrates, and the face loses volume.

The Hyaluronic Acid Booster Serum has been Novexpert’s top seller for over 10 years, with more than 800,000 units sold thanks to its innovative formula that changes everything:
3.2% pure Hyaluronic Acid: one of the highest concentrations on the market, with 4 complementary molecular weights for 4 visible effects. Smooths · Hydrates · Plumps · Fills wrinkles

Approach Results Description Usage Ingredients Comparison

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: Hyaluronic acid is depleted...

Hyaluronic acid is naturally produced by the skin. BUT its production slows down with age: -50% by age 50 & almost no hyaluronic acid left in the epidermis by age 75, if nothing is done.

OUR SOLUTION

3.2% pure hyaluronic acid in a serum. More than 1 billion hyaluronic acid molecules in one drop. One of the highest concentrations on the market. Available for everyone, anytime during the day.

PROBLEM 2: A single hyaluronic acid is not enough.

The effectiveness of hyaluronic acid depends on its size and molecular weight. There are 4 types, each providing a different benefit. Today, most treatments offer only one or two.

OUR SOLUTION

4 serums in 1. 4 molecular weights for 4 benefits. Hydration and plumping effect thanks to very high and high molecular weights. Smoother and firmer skin thanks to medium (100-500 kDa) and low molecular weights (>20 kDa).

PROBLEM 3: Poorly controlled quality!

On the market, the origin, quality of hyaluronic acids, and the accuracy of their molecular weight are poorly controlled, even though this is crucial for safety and effectiveness.

OUR SOLUTION

Verified molecular weights, infrared control, rejection of very low molecular weight hyaluronic acid (<20kDa), potentially pro-inflammatory according to the literature.

PROBLEM 4: the skin no longer learns to produce it.

Providing hyaluronic acid to the skin is important. Teaching it to produce more on its own is essential. Unfortunately, this biomimetic aspect is rarely included in traditional skincare.

OUR SOLUTION

A treatment that is not limited to hyaluronic acid but also contains a polysaccharide, capable of boosting natural synthesis in the skin.

PROBLEM 5: Sometimes misleading tests...

In the cosmetics market, the evidence of the effectiveness of treatments varies in reliability. Tests on active ingredients, satisfaction studies, real clinical trials on the product—it can be difficult to make sense of it all.

OUR SOLUTION

Clinically tested effectiveness under medical supervision, like 100% of Novexpert treatments. Result: up to 76% reduction in wrinkles in 28 days* and skin 49% more hydrated* in just 15 minutes.

Our scientific differences
Scientific difference No. 1
4 serums in 1: thanks to the 4 molecular weights of hyaluronic acid because applying hyaluronic acid alone is not enough.
It is important to ensure its diversity in size and molecular weight to provide the targeted benefits: smoothing, hydrating, plumping, and filling wrinkles. The Booster Serum contains 4 sizes of hyaluronic acid for 4 different actions within the skin.
Scientific difference No. 2
One of the highest concentrations of hyaluronic acid on the market.
3.2% pure hyaluronic acid, which means more than one billion hyaluronic acid molecules in a single drop. The Novexpert Doctors conducted hundreds of tests to achieve this formulation feat. While some players may be tempted to dilute hyaluronic acid to capitalize on its reputation without truly investing in the formula, Novexpert Laboratories choose the opposite. An ultra-concentrated serum, containing the equivalent of 40 hyaluronic acid injections*. A unique treatment that hydrates, plumps, fills, and smooths in just a few drops.
Scientific difference No. 3
A biomimetic dual action. This serum respects the natural functioning of the skin by providing biomimetic hyaluronic acid, meaning identical to the one it naturally produces, and also stimulates endogenous synthesis.
Deliver biomimetic hyaluronic acid
The hyaluronic acid serum contains 3.2% pure hyaluronic acid. Hyaluronic acids of different sizes but with the same structure as the hyaluronic acid produced by your skin.
These hyaluronic acids integrate perfectly into the skin matrix and can be used by the cells just like endogenous hyaluronic acid.
Stimulate the natural synthesis of hyaluronic acid
To go even further, the Novexpert Doctors have included an active ingredient that stimulates the synthesis of hyaluronic acid by skin cells: +31% hyaluronic acid synthesis by keratinocytes.
A natural mechanism to boost the skin’s own production of hyaluronic acid, without making it dependent on external supply.
Scientific difference No. 4
Not all hyaluronic acids are the same.
Novexpert quality guarantee: 100% of hyaluronic acids are tested to make no compromises on skin health and safety.
Quality criterion no.1
Molecular weights of hyaluronic acids verified by infrared spectroscopy (technique used in pharmaceutical production) to ensure their compliance. This rigor demanded by the Novexpert Doctors is essential to guarantee the product's effectiveness and safety.
Quality criterion no.2
No very low molecular weight hyaluronic acid (below 20,000 Da). According to the latest scientific publications, this type of hyaluronic acid could promote inflammation, which is contrary to the desired anti-aging benefits.
Quality criterion no.3
Impeccable purity, manufacturing and packaging of the product in France within our own laboratories and manufacturing plants.
Quality criterion no.4
100% natural origin

La peau colle après utilisation. Résultats pas encore visibles

Bonjour,

Merci pour votre retour.

Afin d’éviter l’effet collant après application, nous vous conseillons d’appliquer le produit sur peau légèrement humide.

Vous pouvez également intégrer quelques gouttes directement à votre crème hydratante, puis appliquer le mélange sur le visage. Cela permet généralement une meilleure absorption et un fini plus confortable.

Les résultats peuvent nécessiter un peu de temps avant d’être visibles, selon votre peau et la régularité d’utilisation.

Nous restons à votre disposition si vous avez la moindre question.

Belle journée.

FAQ

What is the purpose of the Hyaluronic Acid Booster Serum?

Our Hyaluronic Acid Booster Serum is our signature treatment. We formulated it to help the skin become more hydrated, plumper, and visibly smoother. Thanks to its concentrated formula with 3.2% pure hyaluronic acid and a combination of 4 sizes of hyaluronic acid, it works at different skin levels to address the needs of dehydrated skin, tired faces, and marked skin.

What does it mean, 4 sizes of hyaluronic acid?

We chose 4 molecular weights of hyaluronic acid so the serum acts complementarily. Some sizes contribute more to surface hydration and smoothing, while others help with plumping and anti-wrinkle effects deeper within the skin.

Is it a good anti-wrinkle serum?

Yes, that is one of its main benefits. Our Booster Serum helps smooth the skin, visibly plump features, and reduce the appearance of wrinkles. That’s exactly why it has become a staple in the range.

Does the Booster Serum really hydrate the skin?

Yes. Hyaluronic acid is known for its ability to retain up to 1000 times its weight in water. Our Booster Serum is designed to provide intense hydration and help limit the appearance of dehydration fine lines.

Who is this serum for?

We especially recommend it for combination, normal, and dry skin, as well as dehydrated skin, tired faces, and skin that needs plumping.

From what age can this serum be used?

Our Booster Serum can be included in a routine as soon as the skin shows signs of dehydration or fatigue. In our training materials, it is notably presented for use from age 25.

How do you use the Hyaluronic Acid Booster Serum?

Take a few drops and apply them over the entire face and neck, morning and/or evening. You can use it alone or just before your cream.

How many drops should be applied?

We recommend 1 to 2 drops for combination skin, 2 to 3 drops for normal skin, and 3 drops or more for dry skin.

Can the Booster Serum be used morning and evening?

Yes, absolutely. Our advice is to apply it morning and/or evening, depending on your skin’s needs.

Can this serum be used alone?

Yes. The Booster Serum can be used alone without any other treatment, or as the first step before your usual cream.

Can it be applied before makeup?

Yes. We even recommend not waiting long before applying makeup. The texture has been designed to remain pleasant upon application.

Can you target specific areas of the face?

Yes. You can apply it all over the face but also focus on certain areas, such as fine lines around the eyes or wrinkles around the lips.

Is this serum suitable for dehydrated skin?

Yes, that is one of its main indications. If your skin feels tight, uncomfortable, looks tired, or shows signs quickly, our Booster Serum is specifically designed to help restore a more supple, plump, and better-hydrated effect.

Is the Booster Serum compatible with pregnancy and breastfeeding?

Yes. Our Booster Serum is indicated as compatible with pregnant and breastfeeding women.

Is our Booster Serum natural?

Yes. We formulated it with 100% ingredients of natural origin, respecting our formulation charter.

Is the Booster Serum hypoallergenic?

Yes, it is part of our treatments formulated to also suit sensitive skin, with a strict approach to composition.

Is the Booster Serum vegan and made in France?

Yes. Like the rest of our range, it is vegan and made in France.

What does the Hyaluronic Acid Booster Serum contain?

Its formula is based notably on a combination of several forms of hyaluronic acid, as well as hydrating and soothing active ingredients like glycerin, sodium PCA, sodium lactate, aloe vera, and a lactobacillus ferment.

Why do you say this serum is equivalent to 40 hyaluronic acid injections?

We are referring here to an equivalence in the amount of hyaluronic acid in the bottle. A 30 ml bottle corresponds to the equivalent of 40 injections in terms of hyaluronic acid quantity. This illustrates its exceptional concentration level.

How long does a bottle last?

With a usage of about 2 to 3 drops per day, a bottle generally lasts between two and three months.

Which size should I choose?

The 30 ml size is ideal for regular use. The 10 ml size allows you to try the product or easily carry it with you.

Why include this serum in an anti-aging routine?

Because it combines several sought-after benefits in a complete routine: hydration, plumping effect, visual smoothing, and anti-wrinkle action. It’s an excellent daily step to help the skin appear more plump, supple, and smoother.

Can this serum be used before or after a cream?

Yes. We advise applying it before your cream or using it alone if that suffices for your skin.

What visible result can be expected?

Our goal with this serum is simple: to help you regain smoother, plumper, more comfortable, and visibly better-hydrated skin from the first applications, then more beautiful skin over time with regular use.
