I always have pimples on my back, and the old ones get better, and the new ones start to grow again, and it goes on and on. Besides, the weather is not hot now.

Don't squeeze directly with your hands. There are many bacteria on your hands, which is easy to get acne inflammation, and other good places are also easy to grow acne. Improve your diet, try not to eat too much fried and spicy food, eat more light food and get enough sleep. If you have acne, you can also stick potato chips on it, dry it, cut another piece and stick it on it. It must be a thin piece, so that your acne will slowly fade away. Hold on for a few days. This is easier to use. I used it, and it doesn't even have a mark.
