Acts on inflammation mediators

Dermatherm, peaux sensibles

Moisturising is a crucial step to healthy, glowing skin. It is the secret to soft, plump and supple skin.

Generally speaking, the best friends of sensitive skin are neutral products: without perfume, without preservatives and with the minimum of ingredients. They serve to moisturise and protect by replenishing the skin's surface film. Some formulas go further in defusing sensitivity. This is the case with Dermatherm's Optimal Tolerance daily soothing moisturiser.

With its optimal combination of Cevennes thermal spring water, organic Aloe vera and a seaweed complex coupled with a natural washing base, this care product deactivates inflammatory reactions by acting on the neuropeptides released in the skin.

This daily care, specifically developed for sensitive skin, even the most intolerant, acts on the mediators of inflammation. It relieves sensitive and uncomfortable areas while helping to reduce skin redness.

Tested and approved

This daily moisturising and soothing care product has been tested under dermatological control by the Dermatherm laboratory on 20 volunteers with sensitive skin for 2 weeks. The results of this study are as follows :

+ 31% Soothing effect

+ 74% moisturising effect

When signs of discomfort appear, such as redness and tightness, it is because the skin has become sensitive. This can be due to an unexpected change in temperature, but not always. In any case, it is a sign that our skin needs to be pampered :)

3 marine algae for sensitive skin

Extrait d'algues marines

This moisturising and soothing daily care contains coralline. It is a red seaweed that contains a variety of ingredients that can help remove dead skin cells, eliminate free radicals and hydrate the skin, similar to an anti-aging treatment. It hydrates the skin, brightens it and makes it smooth.

A second algae is part of the formula : Laminaria ochroleuca. Also known as golden seaweed, it is known to reduce photo-induced ageing by strengthening the hydrolipidic barrier of the epidermis. In addition, it has an important soothing activity as it decreases inflammation mediators in the epidermis, it also increases skin hydration and limits the natural evaporation of water through the dermis and epidermis.

Finally, a third algae is included in the composition of this treatment, alginate. It is a complex molecule extracted from alginic acid, a viscous liquid contained in the cell walls of brown algae. Their gelatinous structure gives them a moisturising effect, retaining water thanks to their hydrophilic effect. At the same time, the polysaccharides have a protective, skin toning and structuring effect on the dermis, as well as being anti-inflammatory and softening.

Cosmetic UHT sterilization

All Dermatherm products are UHT sterilized (world patent). Today, this is the only way to eliminate any preservatives or stabilizers, while preserving the quality of the active ingredients. UHT sterilisation consists of raising the temperature of the product to 135°C for a few seconds and then cooling it just as quickly. Tests are carried out before and after sterilisation to ensure the preservation of the active ingredients.

Focus on the Dermatherm thermal water of the Cevennes

Dermatherm et son eau thermale

The thermal spa of Les Fumades-les-Bains (France) is approved for its dermatological cures. Its thermal water is recognised by the Academy of Medicine for its therapeutic benefits.

The water of Les Fumades-les-Bains contains thermal sulphur (the most sulphurous in Europe), calcium, magnesium and copper. The sedative effect of magnesium compensates for the tonic action of sulphur. The presence of calcium explains the very good tolerance of the water. Copper has a beneficial effect on acne, eczema, psoriasis and pruritus (itching). In addition to these complementary actions, thermal sulphur plays an essential role in improving the natural immune defences.

This mineral balance gives it anti-allergic, antihistaminic, healing and sedative properties for inflammatory phenomena.

Sheltered from any contamination, and located at the foot of the Cévennes National Park, the site that supplies the spring is a privileged area. There are no large towns, no heavy industry and no intensive farming. The path of the water through the geological layers determines its particular characteristics : its constant composition, its exceptional purity and its balance in trace elements.

This exceptional quality water enriches the purified formulas of Dermatherm skin care products.

Why avoid preservatives ?

Dermatherm, peaux normales à sèches

What is a preservative ?

• What is a preservative ? A chemical substance that preserves a product by limiting bacterial proliferation

 Note that even certified organic cosmetics contain one or more preservatives (selected from an authorised list).


Why are we better off without them ?
They do not help the skin, on the contrary.
Preservatives are often irritating and allergenic. They attack the skin's microbiome, the balance of which is essential to the skin's good health. Many of them, such as paraben, are suspected of being a health hazard.

The Dermatherm product range contains 0% preservatives.
