Personal experience: I don't use cosmetics, so the probability of pore blockage is relatively high. At the same time, my work requires long-term contact with computers, so I wash my face cold every once in a while, which can keep my face clean, better than anything else! At the same time, try not to touch greasy and spicy things in your diet. This can better improve your skin! But this is my personal experience. You can try! And don't take more medicine. As the saying goes, medicine is three points toxic, just like vitamin supplementation. You can make up for it by eating fresh fruits and vegetables.
