First, wipe your nose hard. You usually have a runny nose when you have a cold. Moreover, most people will vigorously wipe their noses with paper towels, thinking that only in this way can they clean their noses and make them clean and comfortable. But in doing so, the position of the alar will be squeezed and the alar will gradually become larger. If this goes on for a long time, the nose will get bigger and bigger.

Second, squeeze the blackheads by hand. We often find black heads on our noses, and many people can't help squeezing them with their hands. But when you are squeezing, you are squeezing your nose, so your nose will get bigger and bigger. Moreover, the skin on the nose will have problems such as loose skin and large pores due to excessive pressure, and bacteria on the hands will also penetrate into the skin. There may be problems such as acne and inflammation.

Third, always pinch your nose. Often pinching the nose will cause the nose and nose wings to get bigger and bigger, making the nose look big and swollen. And often pinching the nose may cause nasal discomfort, which may lead to rhinitis and other situations. So don't pinch your nose when it's okay!

Fourth, I used to touch my nose with my hands. Many people have the habit of touching their noses when they are thinking or staring blankly. Touching the nose often will cause the skin around the nose to be rubbed, and the skin on the nose will cause melanin precipitation due to friction, thus the nose will be black.
