有聽過一個說法，玉米澱粉會容易導致粉刺痘痘，求專業人士來說說？
"Cornstarch is a flour derived from corn and can seem to have great oil-absorbing capabilities," Tiffany Crews, a licensed master aesthetician and clinical oncology aesthetician at the Virginia Dermatology & Skin Cancer Center, explains. "However, cornstarch is a food source with no preservatives, so when exposed to moisture it can breed fungal or bacterial substances. This can happen if someone starts to sweat while the cornstarch is present on her face, which can lead to breakouts and inflammation." And the same goes for cocoa powder. Yikes!
Now I know why I have a breakout all over my forehead....
