I used quarantine. My skin is very dark, probably because I have lived by the sea since I was a child. I think isolation is better than foundation. People with oily skin like me will clog pores with foundation. I bought foundation several times in my freshman year and gave it to my classmates. Now the isolation is very good, not only can polish the air, but also can isolate the air. Many isolations have the effect of sun protection. This is the sunscreen I use in summer. It's too oily to use.

You just need to rub some insulation and spread a layer of loose powder. If you want to treat both the symptoms and the root causes, you should take good care of your skin. This is the fundamental way to solve the problem.
