Scientists from Kongju National University in Korea have proven that applying foundation before exercise can lead to acne and dry skin. Research results published In the Journal of Cosmetic Dermatology (JCD).
43 Korean students participated in the experiment. More than half of the participants (23 people) were girls. Before starting the study, all participants filled out questionnaires confirming the absence of serious diseases and allergic reactions. Scientists cleaned the participants’ faces with micellar water and measured the subjects’ pore size, skin moisture, elasticity and oil levels using special devices.
Foundation was then applied to half of each participant’s face in the T-zone (forehead and nose) and U-zone (lower jaw, cheeks, cheekbones, and temples). The other half of the face remained clean. The volunteers were then asked to do a 20-minute exercise on the treadmill.
As a result of the re-evaluation of skin quality indicators, it was revealed that skin moisture and elasticity increased slightly after training, and this effect was more pronounced in areas where foundation was applied. Additionally, physical activity caused the pores on the face to increase in size, becoming more visible in areas without foundation.
Researchers explained that makeup prevents moisture and sweat from evaporating from the skin surface, which can contribute to the appearance of inflammation on the face.
In addition, the results of the experiment showed that the areas of the face covered with foundation were drier after training, and there was less sebum on their surface. This indicates that such agents can reduce the moisture content in the stratum corneum of the epidermis.
