First of all, let me tell you why your acne grows on your neck because of poor lymphatic circulation. After the long-term liver burden is aggravated, acne will appear at the junction of ears, neck and face, which will erupt repeatedly in the same position and rise to poor lymphatic circulation.

So I suggest you use alkaline soap and sulfur soap. Wash the acne area on your face once or twice a week. After a few months, the effect is very remarkable. (Especially sulphur soap is very effective in washing acne on the back). In terms of diet, you can choose diet therapy, especially greasy and spicy food, and it is best not to touch it. Eat more mung bean soup and other green drinks.
