There are many red pimples on the chest and back. What should I do?

First of all, drink plenty of water, have a light diet, eat more fruits and vegetables, cakes and sweets, and eat less spicy food.

Then, don't squeeze with your hands, it will not only hurt, but also hurt your skin and leave acne marks.

Finally, wash your face at night and put some makeup on the acne area, and it will be fine in a few days.
