Institut Esthederm: A unique approach to cosmetics
Institut Esthederm’s starting point
Jean-Noël Thorel, a French pharmacist and cell biologist, has shaken up the certainties of the cosmetics industry with a disruptive yet respectful approach: ecobiology, or the art of preserving the skin’s ecosystem by reinforcing its natural mechanisms. Rather than over-treating the skin, we need to teach it to live…
Esthederm sun care products are unanimously acclaimed by the women’s press. This success is due to a range of suncare products that make it clear that all skin types have a right to the sun.
Aging, intolerance, brown spots… these are the sun indications that gave birth to products that are now cult favorites: Bronz Repair, Adaptasun, Intolérances Solaires, Photo Reverse.
Jean Noël Thorel then developed the patents and technologies that would underpin the effectiveness of every facial, body and sun care product, and laid the foundations of the Esthederm philosophy: biology at the service of beauty.
The Eau Cellulaire (tissue water mimetics), Repair (dermal repair), UVinCellium (intracellular protection without filters or screens) and Time Control System (antioxidant) patents are some of the most advanced responses to the challenge of ageing.
A pioneer in research into skin flora and its ecosystem, the microbiome, he developed a professional cleaning method:Osmoclean , which won the confidence of many beauticians.
Today, the performance and effectiveness of its formulas, the trust and respect of beauty professionals around the world, and the loyalty and attachment of its users, make Institut Esthederm a benchmark in skincare and suncare. Dedicated to all women concerned about preserving the youthfulness of their skin.
The most advanced solutions for ageing.
Cellular Water

Cellular water is at the heart of every Esthederm formula
This patented antioxidant water, which stimulates cellular mechanisms, is at the heart of every Institut Esthederm product.
Water, the main component of a cosmetic product
Did you know that water is the main component of a cosmetic product? On average, a cosmetic product contains 70% water, which is necessary for its formulation. Conventional cosmetics contain mostly distilled water, which is neutral and has no useful properties for the skin. At Institut Esthederm, we have selected cellular water. This unique water is a genuine ingredient that provides 100% active skin care.
Biomimetic water that’s as close as possible to the water in the skin
Eau Cellulaire is an active water precisely defined for its qualities similar to the water naturally contained in the skin: pH or acidity, concentration of mineral salts, resistance to oxidation.
This characteristic gives Institut Esthederm products an excellent affinity with skin cells:
- It recreates a natural environment that suits them perfectly
- It stimulates the cellular mechanisms that preserve youthfulness: cells live better.
- Cells’ health capital is preserved, and their ability to fight ageing and external aggressions is strengthened. Its antioxidant action prevents the degradation of collagen, elastin and hyaluronic acid.

No. 1
With the sun, not without it
The company was founded by a sun-loving pharmacist-biologist whose convictions and stances run counter to conventional wisdom. There can be no life without the sun, because man was born from the sun.
N° 2
Unequal skin exposure to the sun is not inevitable
InstitutEsthederm’s founder, who grew up with sun-allergic skin, came up with a cosmetic innovation: sun re-education, the basis of the Sun Intolerance Treatment technology, which allows sun-reactive skin to be exposed to the sun.
Its formula diffuses ingredients deep into the skin, enabling it to adapt to the sun and tan, without triggering intolerance reactions. All skin types have a right to the sun.
No. 3
Adapting to the sun, rather than overexposure
Allowing just the right amount of sunlight through is necessary for the synthesis of melanin, a natural protective pigment … and a very sexy one at that. A positive approach to the sun: no race to the top.
No. 4
Tanning is the best form of protection
Under the action of UV rays, melanin synthesis increases, accelerating its ascent to the upper layers of the skin. Tanning is a natural protective system against sunburn, DNA damage and oxidative stress.
This was the inspiration behind the Adaptasun tanning patent, for a faster, longer-lasting tan.
N° 5
Tanning doesn’t age you
While sun exposure triggers the beneficial synthesis of melanin, it can induce cellular damage that our skin is naturally programmed to neutralize: our cells are equipped with self-defense systems against excess free radicals and DNA damage.
Global Cellular Protection is designed to neutralize sun-related cellular and tissue damage.
N° 6
SPF is not a sufficient indicator, it only gives information about sunburn.
The SPF – used by the entire industry – does not tell the user anything about a product’s ability to preserve the skin’s youthful appearance. It indicates the level of UVB protection (responsible for sunburn).
The many quantitative and, above all, qualitative parameters that an Esthederm suncare product takes into account when dealing with the sun’s rays cannot be reduced to a single figure: UVA is just as, if not more, important than UVB.
It is this fight against insufficient SPF that will give Esthederm its now cult hallmarks: Gentle Sun / Moderate Sun / Strong Sun.
Institut Esthederm “suns” allow you to choose the sun care product best suited to the intensity of the sun.

4 different skin types
Tolerant skins: they tan quickly, are generally dark and rarely sunburn.
Tolerant, sensitive skin : it burns faster than it tans. They are pale, even milky, and blush easily, like those of young children.
Intolerant skin: reacts abnormally to sun exposure, with redness, burning and discomfort.
Sun-deficient skin: weakened by medication or hormonal treatments, pregnant women, scars, pigmentation spots.
