Sensitive skin has physiological differences compared to normal skin (read: The sensitive skin). More delicate, it supports fewer products and requires the use of an adapted care routine, in order to provide maximum protection and hydration. Rigorously selected natural ingredients combined with innovative formulation techniques can help these fragile skins.

In people with sensitive or atopic skin, the barrier function is defective (read : The sensitive skin). The composition of ceramides and other fatty acids that serve as cement between the cells of the stratum corneum is weakened. The epidermis is then no longer able to ensure proper protection from the environment: the penetration of pollutants or allergens is facilitated, leading to inflammation reactions, redness and irritation, as well as increased drying.
Vegetable oils rich in various fatty acids, and vegetable butters rich in unsaponifiables, will help restore the barrier function by providing the skin with key elements for its proper functioning.
For example, chia and raspberry oils are very rich in polyunsaturated fatty acids (PUFAs) such as linoleic acid and linolenic acid, which constitute more than 80% of the composition of these two oils. These fatty acids will have an anti-inflammatory action, and will reduce the drying of the skin. In addition, linoleic acid is an essential fatty acid of the barrier function since it is from this fatty acid, among other things, that ceramides are synthesized.
Coconut and shea butter, which are very rich in unsaponifiables, will provide the skin with nutrients that improve its tone and reduce inflammation.

In addition to vegetable oils and butters that will hydrate the skin by providing it with the necessary fatty acids, other active ingredients also help to strengthen its hydration. This is the case of aloe vera leaf juice, known for its moisturizing, soothing and emollient properties, which will quickly soothe irritations in sensitive skin.
Sugars, also known as polysaccharides, are naturally present in the skin and allow good communication between the cells of the epidermis. When applied as a reinforcement to the skin, polysaccharides will reduce water loss by forming a protective film on its surface. By restoring an effective barrier function in sensitive skin, they improve hydration and calm irritation.
Lavender also has many beneficial properties for sensitive skin. It is antiseptic, anti-inflammatory, soothing and restructuring thanks to the presence of mono and sesquiterpenes. It is used to promote healing in case of burns and sunburn. It also has a calming effect on itching in very dry or atopic skin.

The microbiota, our unique skin microflora, is often weakened in people with sensitive skin. Its composition is less diversified, and some species can overtake others, to the detriment of the health of the skin (read: The sensitive skin).
The first step to promote the good health of the skin microbiota is to use treatments with a pH as close as possible to that of healthy adult skin (pH between 4 and 5). Then, restoring the barrier function also restores an environment conducive to the good anchoring of microorganisms and their good growth on the skin. Finally, to increase the diversity of the microbiota, it is preferable to feed it well. This is the function of prebiotics, which are most often polysaccharides, to promote the development of microorganisms in the microbiota at the expense of pathogens causing skin disorders. As the beneficial bacteria in the microbiota are better nourished, they proliferate further, their diversity is increased, thus preventing pathogenic bacteria from settling on our skin.

The use of a care ritual specifically formulated to be self-preserving, i.e. without listed preservatives, protects the already weakened microbiota of sensitive skin. Thus the other ingredients of the formula mentioned above will be able to fully fulfill their role and participate in the rebalancing of the skin’s microflora.

• Avoid excessive hygiene
• Avoid hot water, prefer a gentle drying by tapping the skin rather than rubbing it
• Use washing products containing gentle surfactants to avoid removing lipids from the skin. Avoid soap, which is too alkaline and modifies the pH naturally acidic.
• Before going to sleep, cleaning your skin with gentle surfactants is important to eliminate allergens, pollution and perspiration accumulated during the day. Otherwise, these molecules are a source of irritation, their accumulation may cause redness and itching.
• Pay attention to the composition of preservatives in cosmetic products. If so, identify the one suspected to be harmful and avoid applying products containing it.
• In summer, protect your skin from the sun, if possible by using light but covering clothing. Even in hot weather, it is important to keep your skin well hydrated.
• Eat a good diet: as a general rule, increase the proportion of raw fruit and vegetables, and reduce the proportion of industrial foods that are too sweet, salty and fatty (aggravating acne).
• Take time for yourself, to relax. Indeed, psychological stress is a factor that aggravates skin problems.
