Doctor Philippe Allouche's 'out-of-the-box' vision of the skin
To simply put it, our skin can be compared to a house. If the roof is built badly and cannot guarantee protection against external aggressions, everything inside is subjected to stress and becomes vulnerable.
First, one needs to take a closer look at the epidermis to create a surface for youth and radiance. This approach to observe how the epidermis is constantly interfacing with the skin's deeper structures is known as "interface cosmetology". It enables an understanding of how cosmetic active ingredients can act perfectly from the moment they make contact with the epidermis without needing to go through it.
A person has not one but several skins. Our skin's condition changes several times a single day as well as during the course of our lifetimes. Everyone has different "Skin Instant" which can evolve during the course of one day. The artificial categorization of skins as normal, dry or oily provides a poor psychological definition of a skin's condition and only gives a stationary image of the epidermal cosmetic imbalances.
The same epidermis can present balanced, dehydrated zones and hyper-secretion of sebum all at the same time. Inappropriate treatment can easily lead to new imbalances or reactive old ones. For example, an over aggressive product for so called "oily" skins can cause epidermal hydration problems, while a comedogenous or over-rich product used on formally hyper-seborrheic, now apparently balanced skin and trigger a recurrence of the earlier condition.
Lastly, external factors like climate, temperature, air-conditioning, tobacco, pollution, and internal factors like stress, sexual hormones, hygiene and age affect the skin. Biologique Recherche's Methodology addresses all these factors and how they evolve when it treats the epidermis. This is why we talk of "Skin Instants". Biologique Recherche professionals are trained to analyze all these variables and advise the women and men on the treatment that is best suited to their "Skin Instants".
