H2J Serum: Your Secret to Glowing Skin

Discover the H2J Serum, an essential product for healthy, youthful skin. Our revolutionary serum protects your skin from signs of premature aging, without any chemicals, thanks to a 100% natural water-based formula enriched with hydrogen molecules. If you aspire to radiant skin that is less prone to problems, less sensitive and more comfortable, then H2J Serum is your solution.

Hydrogen: a Powerful Natural Ally for your Skin

H2J Serum is a hydrogenated water generator, an innovative technology that enriches water with active hydrogen molecules, the most powerful natural antioxidant known to date. Thanks to its small size, molecular hydrogen easily penetrates the skin barrier to neutralize the free radicals responsible for skin aging. Its effectiveness is supported by international studies, confirming its anti-inflammatory and protective role.

A Natural Anti-aging Shield

Free radicals, present in our daily environment, damage skin cells, leading to loss of tone, elasticity and other skin problems. H2J Serum acts as a protective shield, neutralizing free radicals and preserving the youthfulness of your skin. Unlike traditional creams, our serum penetrates deep to treat skin problems at the source.

Ecological Commitment: Zero Waste

The H2J Serum is part of an ecological approach by reducing waste. Infinitely reusable, it requires only water for its production, thus offering a sustainable and economical solution. With its exclusive PEM membrane, our serum guarantees pure and powerful hydrogenated water, without any unwanted residue.

How it works ?

Our serum, presented in a 15 ml spray bottle, transforms water into hydrogenated water in just two minutes of activation by electrolysis. This hydrogenated water, rich in active molecules, is ready to neutralize free radicals and revitalize your skin. Easy to use, simply activate the serum before each use to benefit from its benefits.

Enjoy Instant Benefits

Use H2J Serum daily, morning and evening, on clean skin before applying your usual cream. Its compact size makes it ideal for use on the go, allowing you to refresh and protect your skin wherever you are. Give your skin the treatment it deserves with H2J Serum, your personal elixir of youth.


H2J Serum: Your Secret Weapon for Radiant Skin

H2J Serum is much more than a simple skincare product, it is a revolution for your beauty routine. Thanks to its exceptional antioxidant power, it protects and preserves the health and beauty of your skin over time.

A Natural Antioxidant Shield

H2J Serum acts as a protective shield for your skin, reducing inflammation and soothing irritations such as sunburn, eczema, psoriasis and acne. Its dual antioxidant and anti-inflammatory action makes it an essential ally, particularly during the summer months when the skin is subject to increased stress.

Preservation of Skin Youth

By increasing collagen synthesis, H2J Serum maintains skin firmness and elasticity, thereby reducing wrinkles, fine lines and other signs of skin aging. In addition, it preserves the skin's hydration, strengthening its natural barrier and preserving its youthfulness.

Easy and Ecological Use

Activated in just two minutes, H2J Serum is easy to use and requires only distilled or demineralized water. Its refillable bottle, equipped with a rechargeable battery, allows up to 20 uses before recharging, thus reducing plastic waste and contributing to an ecological approach.

Studies Prove It

The benefits of hydrogenated water are supported by clinical and experimental studies, confirming its effectiveness as an antioxidant and anti-inflammatory. Research has also shown its potential in treating various skin conditions, such as eczema, psoriasis and acne.

Sublimated Skin Everyday

Integrate H2J Serum into your daily beauty routine for healthy, youthful-looking skin. Use it morning and evening on cleansed skin before applying your usual skincare cream, or take it with you for a refreshing touch-up any time of day.

Trust H2J Serum to enhance your skin and offer it the best of nature, without compromising on quality or effectiveness.

Our story

Since 2012, Comptoir Santé Beauté has been much more than just an online store. It is the fruit of a shared passion for artisanal scents and French know-how . Our adventure began with a simple dream: to introduce our customers to the richness of French craftsmanship, through beauty products and perfumes created with care, respect and love for nature.

Our story begins with a small group of friends, united by the same passion: olfaction. Each of us had a different background, but our love for natural fragrances and craftsmanship brought us together. One day, during a trip to Provence, we discovered a traditional perfumery workshop, where perfumes were made from 100% natural ingredients. This meeting was a trigger. We decided to share this discovery, this know-how and this passion with the whole world.

We started small, working with local artisans and creating a range of authentic products that reflected the beauty and diversity of French traditions . Little by little, the online store grew, but our values ​​remained the same: quality , naturalness and authenticity .

Over the years, our store has become a place of escape for those looking for products that go beyond simple consumption: products that tell a story , that carry within them the richness of the terroir and that celebrate the work of artisans who are committed to preserving ancestral know-how. We have seen customers come back, not only for the quality of our products, but also for the sincere relationship we have built with each of them.

Today, Comptoir Santé Beauté is much more than a brand. It is a community of enthusiasts, creators and dreamers, united by the desire to celebrate beauty in all its forms. We invite you to join this adventure, to discover unique fragrances and to share with us the passion for artisanal scents .
