Women who regularly use makeup and cosmetic products may face a significantly higher risk of developing asthma later in life, according to a new study by the National Heart, Lung and Blood Institute in the United States.

The findings, published in the peer-reviewed journal Environment International, are based on data collected over a 12-year period from nearly 40,000 individuals. The study examined the use of 41 different beauty products, including lipstick, blush, mascara, and artificial nails.

Researchers found that women who frequently used products such as lipstick, cuticle creams, blush, and fake nails were 47 per cent more likely to develop asthma. Even using blush and lipstick alone, five or more times per week, was associated with an 18 per cent increase in asthma risk.

The study did not establish a direct causal link between the cosmetic products and asthma. However, scientists believe that the presence of certain chemical ingredients—shared across multiple beauty items—could be responsible for triggering respiratory issues over time.

"These results suggest that specific chemicals used widely in cosmetics may have long-term health implications," the researchers noted, though they cautioned that further investigation is needed to determine which substances pose the greatest risks.

The study adds to a growing body of research raising concerns about the potential health effects of prolonged exposure to synthetic compounds found in personal care and cosmetic products.

While the beauty industry often assures the safety of its formulations, public health experts have called for stricter regulation and greater transparency about product ingredients.
