Pollution, a little-known link in the vicious circle of atopy
Eczema, or atopic dermatitis, is one of the main inflammatory skin conditions whose symptoms are exacerbated by atmospheric pollution1. During pollution peaks, outbreaks are more frequent and more severe. Combining the right routine with the right products can help to reduce the impact of pollution on the skin.
Pollution, another source of irritation for atopic skin types
Atopy generally occurs in new-born babies from 3 months onwards. It presents as dryness of the epidermis and an alteration of the cutaneous barrier that increases the penetration of allergens responsible for outbreaks of itchiness.
Already altered by the symptoms of atopy, the cutaneous barrier is weakened and made more sensitive by pollutants such as ozone or fine particles. The smallest fine particles, PM2.5s, can even penetrate down to the epidermis.
Moreover, during pollution peaks, the skin's sensitivity and the feeling of discomfort experienced increase considerably: the skin becomes dryer and outbreaks of itchiness are more frequent.
Improving the quality of life of people with atopy-prone skin
For more than 25 years, La Roche-Posay has been committed to improving the quality of life of people with atopy-prone skin types by developing the Lipikar range, specially formulated to strengthen the skin's cutaneous barrier while respecting its sensitivity.
The skin is the first barrier against atmospheric pollution. While scratching can temporarily relieve the skin, it increases the alteration in the cutaneous barrier that can no longer prevent allergens or pollutants from penetrating. And so begins a vicious circle.
Every day, two simple steps can break this vicious circle that is exacerbated by atmospheric pollution:
Enhance your routine during pollution peaks
During pollution peaks, atopic skin types require specific attention:
