Bitter melon tea
Slice bitter melon into thin slices, dry or stir-fry until golden. Accordingly, every day, infuse a small pinch of dried bitter melon with boiling water to drink instead of tea. Maintaining this habit will help housewives detoxify the body, cool the liver, thereby limiting acne recurrence.
However, housewives should also pay attention when using bitter melon because although it is a benign natural ingredient, skin damaged by acne still needs to be carefully cared for.
