Your phone might be making your face red: doctor

[Guide]

People who often tilt their heads low for long hours and whose blood vessels in the skin are more prone to vasodilation (widening of blood vessels) may suffer from facial skin redness because of poor blood circulation caused by bad posture, Liu said.
“Not all facial redness is caused by rosacea, although many people seek medical treatment because they are worried that they might have rosacea,” Liu said.
A 2014 US study showed that only 31 percent of cases of red-face syndrome are due to rosacea, Liu added.
