Abstract
Anti-pollution skin care and cosmetic products are witnessing a significant growth in the last couple of years due to worsening air quality across the world, and increasing awareness and concern regarding the adverse impact of various environmental pollutants on skin. The various pollutants, like particulate matter, oxides of nitrogen and sulphur, ozone, and polyaromatic hydrocarbons damage skin by different mechanism resulting in skin dryness, loss of firmness, dark spots, uneven skin tone, fine lines and wrinkles, aggravation of acne, and inflammation. The task of developing globally harmonized products is very challenging due differences in skin types according to ethnicity, variation in seasonal weather pattern, differences in benefit expectations, and variances in personal care and cosmetics usage habits of consumers in different regions of the world. However, an increasing understanding about the mechanism by which various pollutants damage the skin manifesting into various extrinsic signs of skin damage and development of various actives that counter the impact of different environmental aggressors has helped formulators to develop different products and to establish efficacy by in vitro and in vivo tests. The article summarizes approaches for formulation development, and a list of few actives classified based in their mechanism action is given. A representative list of products based on their mechanism of action is also given and few potential opportunities for the future are suggested.

Anti-pollution skin care and cosmetic products are witnessing a significant growth in the last couple of years due to worsening air quality across the world, and increasing awareness and concern regarding the adverse impact of various environmental pollutants on skin
Though the anti-pollution movement first began in Asia Pacific region, it is moving into western markets and hundreds of commercially successful products can be seen in nearly every major market across the world [2]
Self-evaluation by consumers has confirmed that skin quality is impacted by the bad environmental conditions and depending on skin type, people observe an aggravation of their skin problem e.g., dry and dull skin, dark spots and uneven skin tone, wrinkles and fine lines, oily skin and acne, sensitive skin, and imperfection [18]
Summary
“Anti-pollution” is one of the recent buzz words in Personal Care and Cosmetics industry and “Anti-pollution” products are witnessing significant growth in the last couple of years due to combination of several factors some of which are:. Worsening air quality in large metro cities in Asia as well as in the West; growing urbanization and increasing visibility of pollution; increasing awareness and concern about the adverse impact of environment pollution on health, wellness, and beauty; better scientific understanding of impact of environment pollution on skin; development of many new active ingredients to protect skin from the adverse impact of environmental aggressors; launch and promotion of many products claiming wide range of benefits; and, development of hybrid/multifunctional products leveraging the existing habits to deliver anti-pollution benefits
