A new study warns women against applying foundation on their face while exercising, highlighting its harmful effects on the skin and pores. The research team used a skin analysis device to examine the skin of 43 healthy participants (20 males and 23 females) before and after a 20-minute walking exercise. The researchers applied foundation to half of the face (the forehead and upper cheek), while the other half remained clean.
They discovered that moisture increased after exercise in all areas of the face. However, the team noted a greater increase in moisture in the areas covered by makeup, which prevents moisture from evaporating from the skin. The size of the pores on the makeup-free skin increased after exercise, suggesting that applying foundation may clog the pores. Meanwhile, the oil levels rose in the areas without makeup and decreased in the areas with makeup.
The researchers wrote in the Journal of Cosmetic Dermatology: "The results indicate that using foundation during exercise can reduce skin oil, leading to dryness. Additionally, makeup can clog pores and increase sebum production (the oily substance). This study provides important insights for individuals and encourages them to consider the potential consequences of using makeup while exercising." When sebum, dead skin cells, and other materials become trapped inside the pores, it can lead to breakouts.
