Peau sensible, réactive, allergique ou intolérante : existe-t-il une différence ?

Sensitive, reactive, allergic, or intolerant skin: is there a difference?

A skin that reacts to the slightest change or following the application of a conventional skincare product deserves your attention. This condition should be closely monitored to prevent skin damage and the permanent onset of redness. Intolerant, reactive, sensitive, allergic... these are just some of the terms that can be used to describe this type of skin. How can we better understand this? Are there differences between all these terms? We answer your questions.

Sensitive skin, intolerant skin, reactive skin... it's all the same!

Sensitive skin, also referred to as reactive or intolerant skin, is a condition, not a type.

As a reminder, there are 4 types of skin (normal, dry, oily, or combination), but it can also be sensitive or allergic.

Sensitive skin is not diseased skin, it is intolerant or fragile due to a deficiency in the barrier function that makes it vulnerable to external aggressions. This lowering of the skin's tolerance threshold can be temporary or permanent.

Several factors are responsible for heightened skin sensitivity: heredity, aging, diet, hormonal imbalance, stress, pollution, certain medical treatments (such as radiotherapy), and UV rays...

Sensitive skin can lead to tingling sensations. Skin discomfort can also manifest as feelings of tightness, burning sensations, or prickling. The face may also display red patches.

Distinguishing between reactive skin and allergic skin.

Theallergic skin reacts to the contact of certain allergenic compounds and not to external aggressions.An allergic reaction is a response sent by the immune system, unlike sensitive skin where the reaction is inflammatory.
A skin allergy is characterized by redness, swelling, eczema, or even hives, most often localized at the point of contact with the offending substance. The reaction occurs every time the skin comes into contact with the allergen. An allergic reaction can appear immediately or within 24 hours following contact with the allergen.

The first step to take if you have allergic skin is to consult your doctor in order to determine the substances to which you are allergic to target products free of these compounds. Generally, hypoallergenic care is recommended. In simple terms, the term "hypoallergenic" means that the product has been formulated to minimize the risk of skin allergies. It thus contains a reduced number of sensitizing substances or is completely devoid of them. Therefore, there is no zero risk for the user in terms of allergies, but it is minimized. In a way, the term "hypoallergenic" means that common allergens are absent from the product's composition. These include, among others, acrylates, parabens, bronopol, nickel sulfate, benzophenone-3, synthetic fragrances, alcohol, dyes, sulfates and even phenoxyethanol. Moreover, it's not just synthetic ingredients that are excluded. Certain essential oils can also be particularly allergenic and will not be present in a so-called "hypoallergenic" formula.

How to take care of sensitive and/or allergic skin?

For those with sensitive and/or allergic skin, it is recommended to favor gentle, hydrating/nourishing treatments and to avoid products containing fragrances and irritating surfactants such as sulfates. Mechanical exfoliants (or grainy scrubs) should also be avoided.

We have developed a soothing serum with 9 specific ingredients especially for sensitive and reactive skin. Minimalist and fragrance-free, it hydrates and soothes the skin while reducing redness from hypersensitivity. It has beentested under dermatological control and contains99% naturally derived ingredients. Its soothing action is primarily due to the beta-Glucan. This natural polysaccharide reduces skin hypersensitivity by stimulating the skin barrier's self-defense capabilities and accelerating the skin repair process. It also has a strong hydrating power.
