You can wash your face with white sugar (the kind with fine particles) and gently rub it with warm water mixed with white sugar for almost 2 weeks. I have used it and think it works well. It's better to remove it.

Pay attention to radiation protection when watching TV online and using mobile phones. It is best to wear isolation, or wash your face after playing. And pay attention to sun protection on sunny days

Eat less soy sauce.

Can supplement VC, Yangshengtang is not bad, DHC is not bad, and they are not expensive. But eat at night, preferably before bed.

Usually pay attention to moisturizing and whitening, you can cook some barley to eat, and the whitening effect is good. But it will take a month to see the effect. If you are in a hurry, you can apply pearl powder (if it is true, all the pieces in a big bag are fake) and honey to your face. The whitening effect is very good and obvious. The effect of eliminating acne marks is better.

I hope it helps you. Don't daydream all day, keep a good attitude, keep a good sleep and drink plenty of water, and your skin will get better and your acne marks will slowly disappear.
