Anti-pollution routine: cleansing, repairing and protecting
In Chinese cities, atmospheric pollution is a major health problem. Among other things, pollution damages and alters the quality of the skin, the first barrier against external attacks.
La Roche-Posay at the forefront of science: an avant-garde epidemiological study in China.
For more than 15 years, La Roche-Posay has been studying the impact of pollution on the skin. Aware of the growing concern on pollution, L'Oréal Research carried out an epidemiological study in Mexico and in China. For the first time in cosmetics domain, La Roche-Posay constituted international expert board and co-signed 3 major scientific publications through highly reputed journals.
These publications made it possible to demonstrate the impact of pollution on the skin, while identifying it as a factor that increases skin sensitivity and exacerbates inflammatory skin conditions: eczema1, urticaria2, allergies3 and acne2 3.
Understanding the harmful effects of pollution
Throughout the day, the skin is in contact with atmospheric pollution and more specifically ozone and PM2.5, microscopic fine particles. These pollutants can stick to the skin, and the smallest particles may even penetrate down to the epidermal cells. They alter the integrity of the cutaneous barrier and prevent it from functioning properly. The result: people with sensitive skin suffering from inflammatory skin conditions are faced with further inflammation.
Moreover, the impact of pollutants on the skin is enhanced by UV rays, the sun and even heat. Under their combined effect, the epidermis becomes more sensitive and particles can stick to the skin more easily. As well as exacerbating inflammatory skin conditions, UV rays and pollution also cause dehydration, oxidation, premature aging and the development of pigmentation disorders.
The steps to take to protect your skin from pollution
Every day, it is necessary to cleanse, repair and preserve the cutaneous barrier and protect the skin to allow it to defend itself against these daily attacks:
- 1Used morning and evening, Toleriane Purifying Foaming Cream cleanses the epidermis and removes make-up by removing pollutants from the pores without irritating the skin. The result: 95% of polluting agents (PM2.5) are eliminated.
- 2Toleriane Ultra Creme complements Toleriane Purifying Foaming Cream by strengthening the cutaneous barrier and preventing PM2.5 from becoming lodged in the pores.
- 3La Roche-Posay sun protection products with SPF 50 protect the skin from UV rays, and more specifically from UVA rays which are the most dangerous, while preventing fine particles - including PM2.5, the smallest fine particles – from sticking to the skin.
Like the face, the neck and the lower neckline are some of the areas most exposed to the harmful effects of atmospheric pollution: use , and any La Roche-Posay sun protection product with SPF 50 to protect them from pollutants.
