Please tell me how to get rid of whiteheads

hello!

These days, I'm focusing on acne management, so if anyone knows how to get rid of whiteheads, please share.

I was relieved that I didn't have any big acne or acne-prone skin, but I guess I let my guard down. I need to get rid of the small acne on my forehead right away!! Sob sob

Why on earth do whiteheads appear?

By the way, if you have any tips on how to get rid of whiteheads without bangs, please share them with me. I welcome all information on home care products and procedures.
