So I think the common skin problem of college students is "dark circles".
Stay up late to play games and play plays every night. A sleepless night is not perfect. ? Staying up late often can lead to eye pigmentation and dark circles. Dark circles are a problem that many people will encounter. They look like pandas. They are particularly unhealthy. There are many reasons for dark circles, such as eye fatigue and aging, but staying up late is definitely the main reason. There are many "national treasures" in universities.
Another problem is that it is easy to get greasy on the face.
I stayed up the night before and woke up the next morning to find my face particularly greasy. If you don't get enough sleep, sebaceous glands will secrete too much oil. The disadvantage of greasy face is that it is easy to cause large pores. Because of excessive facial oil secretion, pores will passively expand, leading to larger pores. Thickening of pores may also lead to acne.
