of skin aging”
At the service of skin’s healthy appearance
Skin’s healthy appearance has always been a quest for us. To create the best solutions for your skin, we developed an expertise based on the comprehensive study of the elements that affect its evolution over time. They are called “the exposome”.
The concept of the exposome comes initially from the cancer research field. It was first defined in 2005 by Professor Christopher Wild, former Director of the International Agency for Research on Cancer (IRAC) as “The cumulative measure of environmental influences and associated biological responses, including exposures from the environment, diet, behaviour, and endogenous processes”. 1, 2
When it comes to the skin, our lab research has shown that exposome is the combination of multiple influences: environmental, behavioral, and hormonal. And, above all: it’s their cumulative effect that can affect the skin’s biological functions and accelerate its ageing. In 2016, we turned these discoveries into a science: Skin Exposome Science.
The multiple elements affecting skin healthy appearance
Skin’s healthy appearance is significantly influenced by many external and internal exposome factors, worsened by their cumulative impact. 15
UVA, UVB, IR, blue light
chemical contaminants, Microparticles PM10 / PM2.5, ultrafine particles, ozone, insecticides etc
- Climate changes:
temperature, humidity, atmospheric pressure variations
nutrition, tobacco, alcohol
- Psychological stress
- Lack of sleep
- Physical activity
puberty, menstrual cycle, pregnancy, menopause
The study of
is a complex
Understanding the exposome means taking into account an infinite number of variables.
That is to say, to take into account multiple influences such as environmental, behavioral, hormonal or the infinite biological skin diversity. Hence, each individual has his own exposome profile. Indeed, an individual will not be exposed to the same factors of the exposome as his neighbor, nor it will trigger the same biological damages on the skin. It is therefore fundamental to understand these factors and to study their cumulative and synergistic effect on the skin to propose personalized solution enhancing skin's potential at every stage of life. For instance, daily light combined with pollution, called Photopollution, may significantly impact skin healthy appearance and aggravate skin aging.”
The effects on the skin
Skin is the human body's largest organ.
Its 4 main functions :
SKIN PHYSICAL BARRIER – SKIN PIGMENTATION – SKIN DEFENSE – SKIN STRUCTURE
are affected by the exposome influencing our skin’s healthy appearance, integrity and quality.
UVs are responsible for 80% of visible facial aging signs. They destroy collagen and elastic fibers leading to aging signs: wrinkles, loss of firmness, rough texture appearance and pigmentation disorders. 3, 4
Pollution causes oxidative stress. It has been proven that it leads to skin aging signs especially dark spots and wrinkles. 5, 6
When combined with UV, it worsens even more skin aging signs. 7, 8
Climate changes such as temperature, humidity, atmospheric pressure can affect the skin barrier function. Cold temperature dries out the skin while warm temperature increases skin hydration and sebum production/sweating, resulting in breakouts, especially for oily skin types. 9, 10, 11, 12
Nutrition directly affects the appearance of our skin and its ability to resist external aggressions, such as pollution, UV rays and stress. A poor diet can cause premature skin aging as well as potential impacts on acne and skin issues (rosacea, atopic dermatitis, and psoriasis). 13
Psychological stress can have an impact on skin both in the short and long term. For example, women who are stressed often present an impaired skin barrier function leading to a drier and duller skin complexion in the short term. 14
Lack of sleep impairs skin barrier function and accelerates overall skin ageing. Skin can look paler, and accentuated fine lines/wrinkles. The area around the eyes is particularly affected. 15, 16, 17
Hormone variation, especially female hormones (such as estrogens and progesterone) can affect the skin structure and composition your entire life and especially during the menstrual cycle (imperfections, breakouts, sebum production increase), pregnancy (imperfections, breakouts, melasma) and menopause. 18, 19, 20, 21
against the exposome
To make skin stronger against the aggressions of Exposome, we put technology at your service: with personalized diagnosis on SkinConsultAI.com, created with dermatologists and skin health experts, you will know your skin priorities. This diagnosis will allow us to propose comprehensive care protocols answering your specific skin concerns with high safety standards.
Our mission to
Our day-to-day mission is to make the science of skin health quality progress and make knowledge accessible to you. Since day one in 1931, Vichy is at the forefront of skin scientific research to accompany women at every stage of life. As a pioneer in Skin Exposome Science and sponsor of our annual research grant, we continue to fund and support the development of scientific knowledge regarding skin’s healthy appearance.
Our researches led in 2019 to the publication, by Vichy Exposome medical board, of “Skin and Exposome”, the first review presenting the biological and clinical impacts of Exposome on the skin, the latest knowledge on pollution impact by hair monitoring and the future perspectives.
To enrich the Exposome knowledge, Vichy publishes studies results every year in renowned dermatological journal or posters and accounts today for more than 30 scientific publications.
